Characteristics of eucalyptus: heavy, sturdy, impact resistant, easy to bend under steam, can be shaped, nail performance is good, but easy to crack. The texture is clear, the wood texture is uniform, the color is soft and smooth. It is heavier than most hardwoods and is prone to cracks during kiln drying and processing.

The materials imported from Europe and the United States are good, and the import price is several times that of domestic beech. Domestically produced same edamame, also known as Cyclobalanopsis glauca, is a wood that differs from eucalyptus wood, structure, wood grain, and has a lower price.

The eucalyptus wood is compact and heavy, the wood grain is thin and straight, and the tissue structure is less. The domestically produced eucalyptus wood is loose, light in weight, wood grain is not obvious, and the tissue structure is more plaques and color difference.

The eucalyptus can grow to more than 30 meters and can reach a diameter of 1.5 meters. The layers of eucalyptus are layered and richer than eucalyptus. Suzhou craftsmen call it “treasure pattern”. The eucalyptus wood is harder than ordinary wood, but it is not hardwood. Among the furniture materials used in the Ming and Qing Dynasties, the coffin has an important position and has been valued since ancient times. Elm is a common material for making furniture in Suzhou. There are also many eucalyptus furniture in the north. Many of them are made up of Ming style and workmanship with Huanghua Pear. They are regarded by craftsmen and collectors.

I don’t know the name in the north, but I call this wood Nanxun. Although it is not luxurious wood, it is widely used in traditional furniture in the Ming and Qing Dynasties, especially in the private sector. This type of eucalyptus furniture is mostly Ming style, and its modeling and production techniques are basically the same as those of hardwood furniture such as huanghuali. It has considerable artistic value and historical value. Alder is a genus of deciduous trees, deciduous trees, high in number, bark hard, taupe, with coarse wrinkles and small protrusions; serrated, slightly thin leaves. Spring is a light yellow flower, unisexual, monoecious. Small fruit after flowering, slightly triangular. This wood is firm and has a beautiful texture for construction and utensils.

Elm is the most common solid wood staircase used in our wood. The difference between heart and sapwood is not clear or clear. Wood white or very light yellowish brown, placed in the air can be turned into light reddish brown, the texture is straight, the muscle structure is fine, uniform, wood luster. Broad wood rays are noticeable, especially on the longitudinal section. Dark stripes or markings appear on the light background. The material has a large variation depending on the growth conditions. The wood is dry quickly, has good properties, and the wood is hard and heavy. Denmark and Northern Europe are harder and harder than others.

The average dry weight is about 961 kg/m3. The strength properties of undried materials are similar to those of European eucalyptus, but the flexural strength, stiffness, hardness, shear strength and tamper resistance of wood are about 20% higher than that of European eucalyptus, and the impact resistance is about 40% higher. Wood has excellent bending properties and is not difficult to process, but it often differs depending on the material.

European eucalyptus is divided into red and white. The two are the same kind of wood before drying. The difference is that the red sorghum has a steam fumigation process when drying, but the white scorpion does not. Therefore, the English name of the red dragonfly is STEAMED BEECH (meaning 'steamed fumace by steam'), and the white peony is UNSTEAMED BEECH (meaning 'cep wood not steamed'). The length of steam fumigation determines the depth of the red wood.

In general, the Italian red dragonfly is darker in color, while the French and Danish colors are lighter. One thing to note is that white pheasant is not white, but lighter pink. The so-called "waterline" is the heartwood of eucalyptus, and the heartwood of eucalyptus is reddish brown to brown after drying. If the heartwood is cut during the process of plate making, there will be reddish brown or brown stripes or ellipses on the plate (depending on the shape of the heartwood) It does not affect the strength and other physical properties of the wood, but it is generally considered to affect the appearance. The eucalyptus boards produced by the mills in Romania, Poland and Turkey generally have more water lines. In general, dried sheets are used in the north and the moisture content should be below 12%. When making stairs or furniture, it should be 8%-10%. When used in the South, it should not exceed 15%.
