DESCRIPTION | Color varies from a golden tan to a reddish brown with some dark grain accents throughout the wood. Kiln dried Cumaru is for interior use. (Rough Sawn Hardwoods & Interior Flooring) Kiln dried lumber outside will expand. Air dried Cumaru is for exterior use. (Exterior Decking) Air dried lumber inside will shrink. |
COUNTRY OF ORIGIN |
South America (Brazil) |
BOTANICAL NAME | Dipteryx Odorata |
OTHER NAMES | Almendrillo, Brazilian Teak, Tonka, and Tonquin Bean |
MECHANICAL PROPERTIES | This wood has a bending strength of 14,793 psi. |
WORKING PROPERTIES | Difficult to saw and bore. Where severely interlocked grain is not present, the wood planes to a smooth surface. Because of its high density and oily nature, the wood glues poorly. It nails and screws well; pre-boring is necessary. |
DURABILITY | Cumaru is very durable. The heartwood has shown to be very durable in resistance to both brown-rot and white rot fungi. The wood has excellent weathering characteristics. |
SEASONING | Cumaru is rated as easy to air-season with a slight tendency to check and with moderate warping; drying was uniformly rapid. |
USES | Outdoor Decking, flooring, cogs and shafts, heavy construction, barge and dock fenders, railroad crossties, pulp mill equipment, tool handles, bearings, turnery. A substitute for lignum vitae. |
COMMENTS | The cumaru tree is cultivated in many areas for the tonka beans used as a flavoring, which have a vanilla-like flavor. |
