The tree

The timber
The pale yellow sapwood is narrow and not clearly defined ; the heartwood is
pale to bright yellow or yellow-brown. It is fine textured, the grain is often
interlocked, sometimes wavy, and the wood has a very lustrous surface.
Moderately hard and heavy it weighs about 690kg/m3 when dried.
Drying
Dries fairly well with little tendency to split and warp.
Durability
Moderately durable.
Strength
Good strength properties, especially in compression along the grain and in
bending.
Working qualities
Works well with hand and machine tools; there is a tendency to pick up when
planing quarter-sawn stock owing to interlocked grain. It takes nails and screws
fairly well, finishes excellently, and takes a high polish if sufficient filler
is used.
Uses
Furniture, cabinet work, ships fittings, flooring, interior joinery. Owing
to the presence of a yellow extractive, which in moist conditions can produce a
yellow dye, the wood is not suitable for use as clothes airers, laundry
equipment.
