GENERAL DESCRIPTION: 

The sapwood of Karri is whitish while the heartwood is pale pink to a reddish brown in color. The species has an interlocked grain and is moderately coarse in texture.

MAIN USES: 

Used for structural components of bridges and buildings (joists, beams, rafters), ship building, furniture, cabinet fittings, flooring, agricultural implements, mine timbers, poles, plywood, and high-quality veneer.

PHYSICAL PROPERTIES:

Karri has a natural resistance to decaying. The wood is reported to have no discernible odor. Karri is very difficult to dry properly due to its tendency to check or warp when the process is rushed. This particular species has a propensity to move over time with changes in temperature and humidity, and as such should be used in areas with a stable climate.

WORKING PROPERTIES:

Karri can dull cutting tools rather easily and as such can pose some difficulty when sawing. Nail installation requires holes to be pre-bored beforehand. Glue holds somewhat well with Karri flooring. This wood requires some effort to sand properly but yields a good polish.
