Weight = light Surfaces may dent or scratch easily Surfaces may dent easily Compression strength (parallel to grain) = low Bending strength (MOR) = medium
Species has medium bending strength in the air-dry condition (about 12 percent moisture content). It is closer in strength to Mahogany than either Teak or White oak, which have higher bending strength. Maximum crushing strength, or compression strength parallel to grain, is low. It is weaker than Mahogany or Teak. It is not hard and can be dented and marred easily. Weight is low. The density is average, or medium.
