Basic density 0.70-0.73gcm

Basic density 0.70-0.73gcm, air-drying density 0.76-0.88gcm3); strength parallel to grain compressive strength 62.0-76.2 MPa, bending strength 121-146 MPa, modulus of elasticity, 17.8-18.1 GPa. nail-holding ability, but vulnerable to termite damage ; heart wood preservative impregnated easier (more difficult Croton Gan Malays). dry and slightly slower, it is prudent operation, or splitting, and warping occurs. sawing Christian Louboutin is not difficult to track due to cross grain planing sawing boards are susceptible to berm stubble;
section smooth (Xu Yong putty filled); peeling performance is still good; good adhesive properties (it is appropriate to urea-formaldehyde glue); finishing of also good. Hard Rock-like strip of non-normal tissue (along the grain length 1m, diameter to the width of 6mm, the tangential width 10mm) wood can increase its strength and drying defects. with a little acid and slightly corrosive metal; case of black iron Easy to use special nails is appropriate. wood use heavy hard wood, strength high, often produces a beautiful cross grain ribbon pattern, suitable for ordinary floor and parquet flooring production.
