Bending strength (MOR) = high Shrinkage, Tangential = small Shrinkage, Radial = very small Shearing strength (parallel to grain) = low Modulus of Elasticity (stiffness) = mediun Max. crushing strength = high Hardness (side grain) = medium Density (dry weight) = 46-52 lbs/cu. ft. Bending strength (MOR) = very high Bending strength (MOR) = medium
Density (dry weight) = 53 - 60 lbs
