Max. crushing strength = high 1 Shrinkage, Tangential = large Bending strength (MOR) = medium Density (dry weight) = 46-52 lbs/cu. ft. Shrinkage, Volumetric = large Shrinkage, Tangential = fairly large Bending strength (MOR) = high Hardness (side grain) = soft Hardness (side grain) = medium Shrinkage, Tangential = moderate Density (dry weight) = 38-45 lbs/cu. ft. Bending strength (MOR) = low Shrinkage, Tangential = small Bending strength (MOR) = very low
