Varies from 610-690 kg/m3 (38-43 lb/ft3), average 650 kg/m3 (40 lb/ft3).
Bending strength – Medium
Crushing strength – High
Stiffness – Low
Resistance shock loads – Low
Fissile and brittle with great dimensional stabillity
Fire and acid resistance
Dries well but rather slowly. Variations in drying rates can occur in individual pieces. Standing trees are girdled and left to dry out for three years before felling. There is small movement in service.
It offers medium resistance to tools but a severe blunting effect on cutters. Tungsten carbide tipped saws are suitable. Pre-boring is necessary for nailing. Gluing is good on freshly planed or sanded surfaces. Fine machine dust is a skin irritant. Stains well and takes a satisfactorily finish, especially an oil finish.
Very durable; liable to insect attack. It is extremely resistant to preservation treatment.
