1. Walnut catalpa wood, also known as walnut catalpa wood, is the walnut tree, walnut wood, and walnut wood produced in the north.
Botanical family: Juglanaceae, English name JUGLAN—DACEAE
Texture: hardwood, softer than oak (oak) and ash (ash)
Age of tree: The mature period is generally 60-80 years to hundreds of years
Characteristics: Very stable, strong plasticity, moderate hardness and softness. Walnut is a world-famous interior decoration material. It is the first choice for making precision wooden instruments such as wooden pallets, instruments and lathe cutting techniques. It is the tree species with the most stable wood properties among all the precious woods in Northeast China;
Famous : The first of the three most valuable tree species in Northeast China, it is known as the "King of World Furniture" in Europe.
Main uses:
One of the tree species that appeared most frequently in the 2008 Olympic Games. A considerable part of the domestically produced "wood branches" used by Chinese Olympic shooters is walnut catalpa. ; Often used in high-end car interiors or high-end home decoration interiors, sniper rifle butts, high-end furniture, and engraving crafts.
Remarks: Catalpa, walnut trees without walnuts are called Catalpa trees. Since the walnut tree laminated timber is more than 40-60 years old, it is actually wrong to call the walnut Catalpa trees on the market Catalpa wood. , because it must have already grown walnuts. The fine pores are an important reason for the stability of walnut trees. At the same time, due to this reason, the amount of paint used when painting walnut trees can be relatively saved.
2. Oak, also known as oak, oak, white oak, English name is oak
Botanical family: Fagaceae, English name FAGACEAE
Texture: Hardwood, harder than most woods
Age: The maturity period is generally 40-60 years to hundreds of years
Characteristics: Extraordinarily hard texture
Reputation: The national tree of the United States, it is one of the most precious tree species besides mahogany and golden teak, which is well-known at home and abroad
Oak is a genus of Quercus japonica and belongs to the beech family. The heart of the tree is yellow-brown to reddish-brown. The growth rings are obvious, slightly wavy, heavy and hard. It is distributed from Jilin in the north, Liaoning to Hainan and Yunnan in the south. However, high-quality wood is rare. High-quality oak still needs to be imported from abroad. Each cubic meter of high-quality wood reaches nearly Ten thousand yuan, which is also an important reason why the price of oak furniture is high.
Characteristics of oak furniture:
Advantages:
1) It has a relatively distinctive mountain-shaped wood grain, and the touch surface has a good texture
< p>2) Higher grade, suitable for making European-style furnitureDisadvantages:
1) There are relatively few high-quality tree species. If imported, the price will be higher.
2) Due to the hard texture of oak, it is difficult to remove the water. Furniture made without dewatering will start to deform after a year and a half.
3) The phenomenon of replacing oak with rubber wood is common in the market. If the customer's professional knowledge is insufficient, it will directly affect the interests of consumers.
Main uses:
It is widely used to make veneers (decorative panels); it is a special wood for holding red wine (called oak barrels); it is the best solid wood floor One of the materials; the solid wood flooring of the weightlifting venue of the 2008 my country Olympics used our oak flooring, which is oak flooring. and making high-end furniture.
Note: Most of the oak seen on the market is Chinese oak. For example, the red oak used in veneer panels is often boiled and dyed red, while white oak is often bleached oak. Then dye it white
Note: There are many solid rubber wood furniture on the market pretending to be oak solid wood furniture. Rubber wood and oak are completely different from each other in terms of material, hardness, economic value, and performance. Completely different trees.
Oak lives in the cold zone, and rubber wood lives in the tropics. Rubber wood is a tropical tree species, belonging to the Euphorbiaceae family (English name EUPHOR—BIACEAE). It is one of the poorer tree species in terms of hardness, material, texture, and performance. Rubber wood is Aged trees that produce rubber juice must be cut down every 15-20 years. They are widely grown in central Yunnan, Hainan, Myanmar and other places. They have two fatal weaknesses:
1) They are rich in sugar and are very It is easy to attract ants and other bugs
2) Since rubber juice is harmful to the human body, rubber wood must be chemically treated before it can be used, but unfortunately, most of the rubber wood on the market has not been chemically treated)< /p>
3. Fraxinus mandshurica, also known as ash, also referred to as ash among the people
Botanical family: Oleaceae, English name OLEACEAE
Texture: hardwood, Softer than oak, harder than walnut catalpa
Age: The maturity period is generally 40-60 years to hundreds of years
Characteristics: Beautiful texture
Famous: Along with Walnut Catalpa and Yellow Pineapple, it is one of the three most valuable tree species in Northeast China
Main uses:
Due to its beautiful texture, it is widely recognized by the market ; Commonly used tree species by well-known domestic solid wood furniture manufacturers; widely used to make veneers (decorative panels).
Remarks: The capillary pores are large and relatively easy to deform.
4. Yellow pineapple
The wood has good luster, straight texture, thick structure, obvious and even annual rings, soft material, easy to dry, good processing performance, and the color and pattern are very smooth. It is beautiful, has good paint and bonding properties, is not easy to split, and has good corrosion resistance. However, due to its poor nailing force, furniture made of yellow pineapple material often has shortcomings such as instability.
Main uses:
Medical use, solid wood furniture.
5. Elm
Botanical family: Ulmaceae, English name ULMACEAE
Texture: hardwood, close to ash
Age: The mature period is generally 40-60 years to hundreds of years
Characteristics: rough texture
Famous: one of the more famous tree species in the Northeast
It is divided into many types, such as yellow elm, thorn elm, etc. There are two kinds of elm trees that are pretty good, among which the elm tree is the best. Thorny elm is produced in the Northeast, and the quantity is very small, so it is basically not available on the market. Some of the more expensive ones we see in the Beijing market are yellow elm and white elm. Yellow elm wood grain is more delicate and beautiful. Yellow elm is not very easy to deform, nor does it shrink as easily as manchurian ash, so it is about the same as manchurian ash, maybe slightly better. In addition, the cheaper elm furniture on the market is all white elm, which is worse than yellow elm, and its deformation and shrinkage are more severe than yellow elm. Most of the northeastern region is dominated by white elm, so a lot of ash furniture in the northeast is mixed with white elm. I learned from some furniture factories in Dalian that many furniture factories there produce elm wood, and then claim that all wood is ash. There is also a kind of elm wood, which is black and the local name is stinky elm. It is the worst.
Main uses:
Due to the rough texture of elm wood, it is often used to make "antique" solid wood furniture, and is also often used to make informal solid wood furniture to reflect its grandeur. , the spirit of being at one with the sky;
Note: The texture is somewhat similar to that of ash, but more rugged
6. Oak
Commonly known as oak wood . Heavy, hard, slow-growing, with clearly differentiated heartwood and sapwood. The texture is straight or oblique, has strong water and corrosion resistance, and is difficult to process. However, the cut surface is smooth, wear-resistant, requires high bonding, and has good paint coloring and finishing properties. Domestic furniture manufacturers mostly use oak wood as raw material.
Disadvantages of oak:
1) Slow growth, long growth cycle (hundreds of years), and few high-quality tree species.
2) The bonding requirements are very high and it is easy to crack at the joints.
3) The processing is difficult and there are many processing defects.
7. Maple
Maple is divided into soft maple and hard maple. It is a temperate wood and is produced from the south of the Yangtze River Basin to Taiwan. It is produced abroad in the eastern United States. The wood is gray-brown to gray-red, with inconspicuous growth rings, many and small pores, and evenly distributed. The maple grains are interlaced, the structure is fine and uniform, the texture is light but hard, and the pattern is excellent. Easy to process, the cut surface is not smooth, and it is easy to warp when dry. The paint has good coating performance and strong adhesion. Mainly used for laminating thin surfaces of boards.
8. Birch
Birch has slightly obvious annual rings, straight and obvious texture, delicate, soft and smooth material structure, and soft or moderate texture. Birch is highly elastic, and its fibers have poor shear resistance and are prone to "stubble breakage." The wood is heavy and not resistant to corrosion. It is prone to cracking and warping when dry and is not resistant to wear. It has good processing performance, smooth cut surface, and good painting and gluing properties. Often used for carved parts, but less commonly used now. The easily distinguishable feature is the many "water lines" (black lines). Birch is a mid-range wood, and both solid wood and veneer are common.
9. Beech wood
Heavy, strong, impact-resistant, easy to bend under steam, can be made into shapes, has good nail performance, but is easy to crack. It is a wood unique to Jiangnan, with clear texture, uniform wood texture, soft and smooth tone. Heavier than most hardwoods, it is prone to cracking when kiln dried and processed.
10. Pine
Pine is a coniferous plant (common coniferous plants include pine, fir, and cypress). It has a pine aroma, a light yellow color, and many boils. , responds quickly to atmospheric temperature, easily swells, and is extremely difficult to dry naturally. Therefore, it requires manual processing, such as drying, degreasing to remove organic compounds, bleaching to unify the tree color, and neutralizing the tree properties to make it less likely to deform.
Northeastern pine
Botanical family: Pinaceae, English name PINACEAE
Texture: softwood, hardwood pine
Tree age: maturity period is 20 years to 30 years
Characteristics: beautiful color, soft texture, easy to deform and crack
Reputation: relatively widely accepted
Main uses: widely used It is used as a material for mid-range solid wood furniture and is widely used in "children's rooms" by well-known manufacturers such as Ximengbao. The anti-corrosion wood used for outdoor materials is generally pine. Northeastern pine finger-jointed boards are sold in B&Q Building Materials Supermarket.
There are many types of pine in the Northeast, including red pine (longer growth period, finer texture, and reddish color), and white pine (shorter growth period, thicker texture). There are many types of white pine. Pinus sylvestris, ichthyosaur pine, and lengsha are all northeastern pine. Pinus sylvestris is easy to change color, and lengsha is the worst quality pine among them and has little use at all.
New Zealand pine (Chile): light yellow in color, straight texture, easy to dry, small deformation, medium mechanical strength, good processing performance, suitable for making furniture and various wood products.
Argentinian pine: yellowish in color, relatively high density, easy to crack, and obvious color difference
Brazilian pine (Uruguay): light yellow in color, clear texture, medium mechanical strength, suitable for production Furniture and various wood products.
Russian pine: It is the same product as Northeastern pine, but it is just because of the difference in national boundaries. Therefore, if Russian pine is used, there is no need to import it.
Remarks: Pine can also be divided into softwood pine and hardwood pine. Northeastern pine and Scotch pine are the hardwood pine among pines and are better pine. White pine and larch are both softwood pine and generally cannot be used. Making furniture, suitable for making earth dragons, etc.
11. Camphor wood
It is found in all provinces in the south of the Yangtze River in my country, and is abundant in Fujian, Taiwan. The trees have larger diameters, wider widths, and beautiful patterns. They especially have a strong fragrance. It keeps insects away and is often used to make cabinets, boxes, cupboards and other furniture to store clothes. This is its advantage; Disadvantage: Modern medicine has proven that the gas emitted by camphor wood contains camphor, alkanes, phenols, and alkenes. Organic ingredients such as camphor and camphor ether have a stimulating effect on the human gastrointestinal mucosa. Once inhaled into the body, a water-soluble metabolite - oxidized camphor will be produced. Therefore, placing camphor wood furniture in the bedroom will affect the quality of sleep. , making people excited and even insomnia; the aromatic smell emitted by camphor wood furniture may also cause symptoms such as dizziness, weakness, nausea, vomiting and other symptoms; pregnant women are prone to miscarriage if they are in contact with camphor wood furniture for a long time; infants and young children are prone to miscarriage if they are exposed to the smell of camphor wood for a long time. stimulation, adverse reactions may also occur.
Elm
12. Chinese fir
Softwood is a fast-growing wood with a maturity period of 4-6 years. Due to rapid production, the natural wood fibers are loose and Because of its high moisture content, it cannot be used to make furniture. It is generally used to make pulp, blockboard, density board, and particle board. Some are also made into finger-jointed boards and used as inner baffles for furniture. It has a long service life while maintaining its original performance. For no more than 5 years.
The value of solid wood furniture not only depends on the wood it uses, but also mainly includes the following aspects:
1. Materials: What are the main materials and auxiliary materials? Different wood materials have different values, and the prices are naturally different.
2. The manufacturer’s processing equipment and process capabilities. Generally, large manufacturers handle wood well. The quality assurance of small workshops will be worse. Even if all the wood used in small workshops is real materials, warping and cracking may still occur in the future due to problems with equipment and technology.
3. Workmanship: The outside is beautifully made, and the internal feel, smoothness and neatness of the workmanship also reflect the quality of the furniture.
4. Auxiliary materials: The quality of adhesive (glue) and paint is also a key point of environmental protection. The more environmentally friendly, the better.
5. Hardware: hinges, slide rails, handles, etc. also have added value. Of course, the quality of big brands is easy to use for a long time.

The solid wood beds currently on the market are mainly made of walnut, oak, and ash. It has strong nail-holding power, good flexibility, high surface hardness and good anti-scratch effect. The most important thing is that the cost is relatively suitable. It can be said to be the best among all types of wood. This is why solid wood beds are now mainly made of these woods. . The density of each type of wood is different, and the price also has a certain gap. In fact, many solid wood furniture now are actually veneered, and only some of the load-bearing parts are solid wood. When choosing good solid wood furniture, first check its workmanship and whether there are gaps between them. seam.
