General Description: Golden-orange to brown,
lighter vessel lines conspicuous on flat sawn surfaces. The material may
contain large, hard deposits of calcium carbonate in cavities and the wood
around them may be darker in colour. The grain is interlocked and
sometimes irregular and the texture rather coarse, but even. The weight is
640kg/m3 (40lb/ft3); specific gravity .64.
Mechanical Properties: This medium density wood has a moderate steam
bending classification with medium bending and crushing strength, very low
stiffness and resistance to shock loads.
Working Properties: The material works satisfactory with hand and
machine tools.. A reduction of cutting angle to 15° is necessary for a
smooth finish in planing quarter sawn surfaces due to interlocked grain.
The wood nails and screws well, glues satisfactory and when the grain is
filled, an excellent finish can be obtained.
Durability: The sapwood is liable to attack by powder post beetle,
but is highly resistant to termites in Africa. The heartwood is very
durable and is extremely resistant to preservative treatment. The sapwood
is permeable.
Uses: Ship and boat building, interior and exterior joinery,
laboratory benches, furniture making and carving. It is a structural
timber suitable for piling and marine work and for domestic flooring. Also
for plywood manufacture and sliced for wall panelling, flush doors and
decorative veneering. |
