Scientific name: Dipteryx spp
Description: Fresh heartwood is reddish brown or purplish brown with light yellowish-brown or purplish streaks; upon exposure gradually becomes uniform light brown or yellowish brown
Mechanical Properties: Janka hardness 2,200 lb. for green material and 3,540 lb. at 12% moisture content. Shrinkage from green to ovendry: radial 5.0%, tangential 7.6%, volumetric 12.0%
Working Properties: The wood is difficult to saw and bore; where severely interlocked grain is not present, the wood planes to a smooth surface. Because of high density and oily nature, the wood glues poorly.
Durability: The timbers have a reputation for being very durable. Laboratory tests also show the heartwood to be very durable in resistance to both brown-rot and white-rot fungi. The wood has excellent weathering possibilities.
Uses: Cogs and shafts, barge and dock fenders, hardwood flooring, tool handles, bearings ,turnery. The substitute for lignumvitae.
