Shrinkage, Tangential = fairly large Shrinkage, Radial = fairly large Shearing strength (parallel to grain) = very low Max. crushing strength = very high Max. crushing strength = high Hardness (side grain) = very hard Hardness (side grain) = medium Density (dry weight) = 53-60 lbs/cu. ft. Density (dry weight) = 46-52 lbs/cu. ft. Bending strength (MOR) = very high Bending strength (MOR) = high Shrinkage, Tangential = large Modulus of Elasticity (stiffness) = high Bending strength (MOR) = medium Shrinkage, Radial = large Modulus of Elasticity (stiffness) = medium Max. crushing strength = medium Density (dry weight) = 61-67 lbs/cu. ft. Weight = very high Shrinkage, Tangential = moderate Resists denting and marring Density = high Compression strength (parallel to grain) = very high
