Kempas — Dense Southeast Asian Hardwood

Kempas — Dense Southeast Asian Hardwood

Kempas is a dense Southeast Asian hardwood known for its orange-brown colour, interlocked grain and demanding heavy-duty performance.

Species profile

Botanical name Koompassia malaccensis.

Range & habitat Native to parts of Southeast Asia, including Malaysia and Indonesia, where it grows as a large tropical forest tree.

Colour Heartwood typically ranges from orange-brown to reddish brown, often becoming deeper and warmer with age.

Grain & texture Grain is commonly interlocked and can be wavy, with a medium to coarse texture.

Workability Its density makes machining comparatively demanding. Sharp cutting edges, controlled feed rates and pre-drilling for fasteners are sensible practices.

Natural variation Some material can contain hard or brittle streaks, so individual boards should be evaluated rather than assuming uniform behaviour.

Odour No strong characteristic odour is generally associated with the wood.

Uses Flooring, heavy construction, railway applications, plywood and other demanding structural or industrial uses.

Identification rule: wood anatomy can often narrow an unknown sample to a genus or group, but species-level identification is not always possible from wood alone. When the evidence does not justify certainty, Exotica keeps the identification conservative.
