Compression strength (parallel to grain) = high Bending strength (MOR) = high The species has high bending strength in the air-dry condition (about 12 percent moisture content). It compares favorably with Teak, which also has high bending strength. Maximum crushing strength, or compression strength parallel to grain, is high. Some familiar species with high crushing strength parallel to grain include Hard maple, Teak, and White oak
