It has excellent mechanical properties, high flexural strength, high compressive strength, medium impact strength and medium hardness.
Drying characteristics
Easy to dry, less degrade, small deformation in the use process.
Processability
Small wear and tear on tools, easy to process; good grip (straight nail, screw) force, strong glue force, easy to paint, can
Excellent finishing effect was obtained.
Durability
Heart wood has strong corrosion resistance, and the impregnation treatment of preservatives is medium.
purpose
Because of its good mechanical properties, durability and dimensional stability, it is an ideal material for joinery, furniture and cabinets. It is also suitable for car making and carving, tool handles, knife handles, levelers, wooden oars and agricultural tools.
Because of its wear resistance, it is suitable to be used as floor material. Because of its good dimensional stability, it can be used as floor material for bottom heating. Selected logs can be planed into veneer veneers of very high quality.
In fact, Yahua pear is not a single kind of wood, but a general term for a kind of wood. There are three types of wood in the genus Pterocarpus: Pterocarpus and Pyrocarpus. ) Non-rosewood of non-rosewood and rosewood is called sub-rosewood. There are more than twenty species of subflower pear trees. The properties of these twenty kinds of wood are similar to those of Huali wood, but they can not fully meet the requirements of national standards in terms of density, so they are called Yahua pear.
At present, there are two kinds of Yahua pear in the market, African rosewood (commonly known as Indian red pear) and Angolan rosewood (commonly known as Khmer wood), which are also called African Yahua pear. These two kinds of wood are classified as sub-flower pear because of their large diameter and relatively small density. They are also called Caohua pear or African sub-flower pear in the market. In addition, the so-called Vietnamese rosewood furniture is also seen on the market. This kind of furniture is indeed purchased from Vietnam, but its texture is similar to Khmer wood. Compared with wood density, it is lower. According to the National Standard, it can not be called Huali wood.
African rosewood is produced in Nigeria, Congo (Bulgaria), Congo (Kinshasa), Ghana, Gabon, Angola, Cameroon and other places. The anatomical characteristics of Pterocarpus Africana are very similar to those of Pyrocarpus rosea in the Southern Ocean. Harder material, medium weight, corrosion resistance and durability; heartwood orange-brown to dark red, often with dark stripes, scratches visible, straight or staggered wood grain, uneven texture; wood shavings or wood chips water extract fluorescent, slightly light aroma.
Red sandalwood of Angola is produced in Africa. It is also a kind of Asian pear wood. Some people also call it African Asian pear. Its sapwood is light gray or yellow, and the color of heartwood varies greatly, ranging from brown to purple-brown, sometimes with dark stripes, lustrous wood with a weak fragrance; texture to slightly interlaced; slightly uniform structure; used for furniture and joinery products, decorative materials, ** floor, musical instruments, carving products, etc.
