The wood is scented and contains resin cells. The wood is very heavy, very hard, flexible. It works fairly well with hand and machine tools, but has a marked blunting effect and stellite-tipped sawteeth are needed. Splitting on nailing and screwing is common, and pre-boring is recommended. The wood glues, polishes, waxes, varnishes and paints well. It is reputed for its resistance to wood rot and insect attack. The sapwood is susceptible to Lyctus borers. The heartwood is very resistant to impregnation. The wood has a wide range of used, being employed in heavy construction, carving, cabinet work, tool handles, interior joinery, interior trim, heavy parquet flooring, sliced veneer, plywood, ship and boat building, railway sleepers, vehicle bodies, electricity and construction poles and cattle enclosures.
