Highly suitable for premium heavy construction due to its low shrinkage and durability.

Saws well, however, with the fairly high incidence of gum, saws tend to become clogged. It planes well but there is a tendency for the grain to tear out in quarter-sawn material. A reduction in the cutting angle to 20º is beneficial. The wood tends to split when nailing but holds screws well and can be stained and polished reasonably well, however, patches of oil that exude may affect the finish. The yellow deposits are soluble in water and the dye produced does stain. If, however, early attention is given to any staining it can generally be removed by scrubbing with milk or lactic acid.

Kwila has high bending strength, crushing strength and stiffness, with medium resistance to shock loads. It has a poor stream bending classification due to exudation of oil.
