Soft Dents or scratches easily Compression strength (parallel to grain) = low Bending strength (MOR) = medium
The 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. It also does not wear well, and mars easily
