Asia) Distribution overview: The species occurs in Central and South America, and is found in Nicaragua, Brazil, Venezuela, Peru, Guyana, Colombia, Trinidad, and Surinam. Common uses: Billiard-cue butts, Boat building (general), Bridge construction, Brush backs & handles, Cabinetmaking, Construction, Decks, Decorative veneer, Flooring, Furniture , Furniture, Heavy construction, Joinery, Light construction, Musical instruments , Musical instruments, Railroad ties, Structural work, Tool handles, Turnery, Vehicle parts, Veneer, Veneer: decorative Product sources: The species is in high demand in Brazil, and is used locally for dug out canoes. The name Vinhatico is applied to several wood genera which are similar in color and have weights of 35 to 40 pounds per square feet (560 to 640 kg/cu.m). The species is also reported by the ITTO to be an important source of timber for export. Environment profile: Environmental status not officially assessed
Tree size: Trunk diameter is 150-200 cm
Colors: the heart isRed, Reddish brownand the sapwoodWell defined, White to yellow.The grain isStriped figure, the textureUniformand the lusterPronounced
Natural durability: Resistant to marine borers, Very durable Odor: No specific smell or taste
Kiln Schedules: Dry at a slow speed Kiln Drying Rate: Naturally dries quickly
Drying Defects: Moderate twist/warp, Tendency to chrck and end-split during drying Ease of Drying: Rapidly Comments: General finishing qualities are rated as good Blunting Effect: Little
Gluing: Glues well
Nailing: Good nailing characteristics, Very Good to Excellent Planing: Sharp tool edges recommended to prevent pick-up when planing material containing interlocked and egular grain Resistance to Impregnation: Resistant sapwood Response to hand tools: Stock containing irregular grain requires sharp cutting edges for best results Veneering qualities: Veneers easily, Veneers moderately easy Steam bending: Responds poorly to steam bending operations
Screwing: Screws without difficulty , Very Good to Excellent Results; Turning: Worked surfaces are relatively clean, especially if cutting edges are sharp
Painting: Poor to Very Poor; Polishing: Satisfactory; Staining: Good staining qualities;
