Common Name: Wadara
Scientific Name: Couratari spp.
Wood Description: Wadara wood, from the Couratari spp. genus, typically has a sapwood that is not distinct from the heartwood. The heartwood itself is cream-colored, often with a pinkish or yellowish tinge. The timber tends to fade upon exposure. It has a medium to coarse texture and a grain that can be straight or uniformly interlocked. The luster of Wadara ranges from rather low to high. While generally lacking a distinct odor or taste.
Physical Properties: Wadara is described as moderately strong and hard. The basic specific gravity (oven-dry weight/green volume) is 0.50, with an air-dry density of 37 pcf (approximately 593 kg/m³). The Janka side hardness is 880 lb at 12% moisture content and 740 lbs. for green material. The average toughness is 124 in.-lb. Shrinkage from green to oven-dry is radial 4.1%, tangential 7.3%, and volumetric 11.3%. The wood is noted for its stability once manufactured.
Mechanical Properties: Wadara’s strength properties can vary depending on its area of origin.The bending strength (Modulus of Rupture, MOR) is 13,520 psi at 12% MC. The modulus of elasticity (MOE) is 1,800 (1000 psi) at 12% MC. The maximum crushing strength is 7,460 psi at 12% MC. These values indicate a timber with moderate strength suitable for general construction purposes.
Uses: Wadara is primarily used for general interior construction and carpentry work. It is also suitable for boxes and crates, furniture components, veneer and plywood, and treated railroad crossties. Its ease of workability and treatability make it a versatile timber for various general utility applications.
