General Description: The colour of the heartwood
varies according to origin. Usually grey-brown with infiltrations of
darker colouring irregularly distributed as streaks of smokey brown. The
grain is straight to wavy, with a rather coarse texture. The figured wood
sometimes forms a well defined central core. Weight averages 640 kg/m3
(40lb/ft3); specific gravity 0.64.
Mechanical Properties: Walnut has medium bending strength and
resistance to shock loads, high crushing strength and low stiffness, and a
very good steam bending classification.
Working Properties: This timber works easily and well with both
hand and machine tools and finishes cleanly, with only a moderate blunting
effect on cutting edges. Nailing and screwing is good; gluing is
satisfactory and the material polishes to a high finish. An easy timber to
carve.
Durability: Moderately durable. The sapwood is liable to attack by
powder post and common furniture beetle, and the logs are susceptible to
Longhorn and Buprestid beetle attack. The heartwood is resistant to
preservative treatment, but the sapwood is permeable.
Uses: This excellent timber is used in the solid and veneer form
for high-class furniture, cabinet making, bank and office fittings, rifle
butts and gunstocks, turnery and carving, doors, sports goods, and
fascias. |
