The common Malaysian name for the species of Caesalpinia sappan (Leguminosae). The sapwood is white with a pinkish tinge and sharply differentiated from the heartwood, which is orange-red, darkening on exposure to dark purple-red brown.
Also known as Mai (Laos); and Sibukau (Philippines).
The timber is hard and heavy with a density of 980-1,045 kg/m3 air dry.
The timber is said to be durable to the weather.
Texture is moderately fine and even. Grain is straight, wavy or spiral.
Wood working properties have been rated as moderately easy and takes a high finish.
The timber has not been tested at the Forest Research Institute Malaysia (FRIM). However, tests elsewhere indicate that the timber is subject to checking and warping when seasoned in the log.
The species is a source of yellow dye, but the timber is also said to be used for cabinet work.
