MECHANICAL PROPERTIES
Janka hardness 2,200 lb. for green material and 3,540 lb. at 12% moisture content. . It is naturally seasoned and then kiln dried to prevent shrinkage. Hardness is approximately 5 times harder than pine, cedar and redwood and over 10 times stronger than composite decking products. : Cumaru’s density, workability, durability and characteristics are nearly identical to that of IPE.
WORKING PROPERTIES
The wood is difficult to saw and bore since Cumaru has an incredible density and strength; 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
