Sapwood yellow-brown; High-strength, corrosion-resistant, termite-proof, moth-proof and marine wood-boring animals; Heartwood preservatives are difficult to soak. It is difficult to process, because the wood is hard and the cutting edge of the tool is blunt, so alloy steel saw blades should be used; Wood grains are staggered, and the planing angle is 15-20 degrees; Smooth section; The coating performance of the filler is good after coating, so it should be handled carefully when gluing. Wood has high strength, great hardness, corrosion resistance and large supply; Suitable for manufacturing floors, sleepers and bridges. It is also suitable for manufacturing hydraulic facilities, seaports and docks, outdoor buildings and heavy structures, heavy woodworking products, gear parts, turning products and decorative veneers with more stable performance.
Bark: 0.5~ 1.5cm thick, hard and brittle, easy to peel. The skin is thin, dry and atrophied to a great extent; Total shrinkage: 7.6%-8.3% in chord direction; Radial 5.0%-5. 1%. Wood has good dimensional stability. The wood is heavy; The basic density is 0.7 1-0.78 g/cm3, and the air-dried density is 0.73-0.8 1 g/cm3; The heartwood is chestnut brown with very clear "cow hair stripes"; Imitation mahogany material.
2.elm tree
Ulmaceae, Ulmus, mainly produced in temperate zone, deciduous trees, tall trees, all over the north, especially in the Yellow River basin, can be seen everywhere. Elm wood is tough, clear in texture, moderate in hardness and strength, and can be adapted to general carved reliefs.

The wood grain is straight, the pattern is clear, the wood has good elasticity, moisture resistance and corrosion resistance. Air-dried density: 0.68g/cm3, wood hardness is moderate, easy to dry, not easy to deform and crack, so it is the first choice for making furniture. Beautiful patterns and elegant colors.
