Density (dry weight) = 46-52 lbs/cu. ft. Shrinkage, Tangential = fairly large Max. crushing strength = high Shrinkage, Volumetric = fairly large Shrinkage, Tangential = large Density (dry weight) = 38-45 lbs/cu. ft. Bending strength (MOR) = high Shrinkage, Radial = small Shrinkage, Radial = fairly large Modulus of Elasticity (stiffness) = low Bending strength (MOR) = medium Shrinkage, Radial = moderate Shrinkage, Radial = large Modulus of Elasticity (stiffness) = high Hardness (side grain) = medium Work to Maximum Load = very low Shrinkage, Volumetric = moderate Shrinkage, Tangential = moderate Shearing strength (parallel to grain) = very low Shearing strength (parallel to grain) = low Modulus of Elasticity (stiffness) = very low Max. crushing strength = very high Hardness (side grain) = soft Hardness (side grain) = hard Bending strength in the air-dry condition (about 12 percent moisture content) is very high
Compression strength parallel to grain, or maximum crushing strength, is very high - higher than in Teak or Hard maple.
