Other Uses

The freshly cut heartwood is a pinkish brown, becoming light reddish brown with a definite coppery or golden look upon drying; it is not clearly separated from the 3 - 6cm wide band of cream-coloured sapwood. The grain is straight to sometimes interlocked - when interlocked grain is present, a mild wavy figure is apparent on the tangential
surface; texture is medium to coarse; lustre is high, but without the characteristic sublustre so well developed in many high-grade cabinet woods; the unseasoned wood has an unpleasant odour, but no distinctive odour or taste is evident in seasoned wood. The wood is moderately heavy, moderately hard; somewhat variable in decay resistance but, in general, is moderately durable. It seasons at a normal rate, with a high risk of checking and distortion; once dry it is poorly stable in service. It has moderately good working properties; saws and planes well; takes nails and screws well; glues satisfactorily; but requires care in polishing. However, it dulls saws and cutting edges rather quickly because of the accumulation of silica in the parenchyma and ray cells - stellite-tipped and tungsten carbide tools are recommended. Chipped or torn grain is likely to occur when roey grain is present, and fuzzy surfaces and tearing are apt to occur in boring[

I ast has also recently been found to be one of the champion carbon sequestering species in the rainforest,suggesting we should move away from its use lumber as quickly as possible.
