Lignum Vitae is one of the hardest and heaviest commercial timbers. The heartwood colour is dark greenish-brown to almost black. The grain is heavily interlocked and irregular and the texture fine and uniform. The weight varies from 1150-1300 kg/m³ (72-82 lb/ft³) averages 1230 kg/m³ (77 lb/ft³); specific gravity 1.23. It has a characteristic oily feel due to its guaiac resin content that constitutes 25% of its air dry weight
Uses: Owing to Lignum Vitae’s self-lubricating properties it is used for ship’s propeller bushes and bearings, marine equipment, thrust bearings, pulley sheaves, wheels, guides, rollers and blocks, mallet heads, “woods” for bowls, cotton gins, dead eyes, die cutting and turning, and for any purpose where lubrication is impractical or unreliable.
