HURUASA Scientific name: Abarema jupunba Family: Legumiosae (Mimosaceae) International trade name: Limonaballi Other names: Klaipio, Kwatpain, Kwatupana, Soapwood Wood Appearance The sapwood is white to yellowish-white and the heartwood is pale brown to reddish brown. The grains are straight to interlocked and the texture is fine to moderately course. Physical and Mechanical Properties • Air dried density (12%) - 620kg/m 3 • Bending strength (at 12%) - 102 N/mm 2 • Modulus of elasticity (at 12%) - 13770N/mm 2 • Crushing strength (at 12%) - 51 N/mm 2 Natural Durability It has moderate resistance to decay. Poor treatability. Timber Processing Drying - Drying is fast. Working - Sawing is easy and machining is good. Assembly - Gluing and nailing is good. Finishing - Finishing is good. Uses Suitable for furniture, interior trim, veneer, utility plywood and light carpentry. Supplies Available Substitute Can substitute for Crabwood, Determa and Hububalli in construction and furniture. 30
KAUTABALLI Scientific name: Licania alba, L.majuscula Family: Chrysobalanceae International trade name: Kautaballi Other names: Countaballi, Counter, Farsha (L. majuscula), Maiuaria (L. alba) Wood Appearance The sapwood is a distinct tan and the heartwood is yellowish-brown to dark brown. The grain is straight and texture is fine. The length of the bole is 15-18m with a diameter of 40-60cm. Physical and Mechanical Properties - (Licania majuscula) • Air dried density (12%) - 1030kg/m 3 • Bending strength (at 12%) - 173 N/mm 2 • Modulus of elasticity (at 12%) - 17400N/mm 2 • Crushing strength (at 12%) - 84 N/mm 2 Natural Durability There is moderate resistance to decay and high resistance to dry wood termites, insects and marine borers. Treatability is moderate. Timber Processing Drying - Air-drying ranges from easy to moderately difficult with slight risk of distortion and checking. Working - Power is required for sawing. The high silica content causes some blunting of saws and difficulty in machining. Special tools are required. Assembly - Pre-boring is necessary. Finishing - Good Uses Heavy construction (above ground), shingles, charcoal, underwater marine construction Supplies Abundant Substitute This species can substitute for Greenheart and Purpleheart in bridge construction and as beams. 31
