They are most common in the Amazon basin, and are also found in Colombia, Guyana, Surinam, and Venezuela. Common uses: Agricultural implements, Bedroom suites, Billiard-cue butts, Boat building (general), Boat building: decking, Boat building: framing, Boat building: planking, Bobbins, Bridge beams, Bridge construction, Bridge joists, Building construction, Building materials, Cabin construction, Cabinetmaking, Canoes, Carvings, Chairs, Chemical containers, Chests, Concealed parts (Furniture), Construction, Decorative veneer, Desks, Dining-room furniture, Docks, Dockwork, Domestic flooring, Dowell pins, Dowells, Drawer sides, Factory construction, Figured veneer, Filter press plates, Fine furniture, Floor lamps, Flooring, Furniture , Furniture components, Furniture squares or stock, Furniture, Handles, Handles: general, Hatracks, Heavy construction, Joinery (external): ground contact, Joinery, Kitchen cabinets, Light construction, Living-room suites, Marine construction, Marquetry, Mathematical instruments, Millwork, Mine timbers, Moldings, Office furniture, Paneling, Piling, Railroad ties, Shade rollers, Skis, Sporting Goods, Tables, Tool handles, Turnery, Vats, Vehicle parts, Walking sticks, Wheel spokes Product sources: The ITTO reports that timber production from this species is regular. The material is exported at a low but regular rate. Supplies are ample, but the wood is fairly expensive. It costs more than mahogany but less than teak. Although it has not found wide demand, Purpleheart is available on the US market in both the lumber and veneer forms. Environment profile: Vulnerable Tree size: Trunk diameter is 150-200 cm
Colors: the heart isPurple, Redand the sapwoodWhite to yellow, Yellow.The grain isWavy, the textureMediumand the lusterSlightly lustrous
Natural durability: Very durable, Very resistant to dry-wood termite attack Odor: No specific smell or taste Kiln Schedules: UK=E US=T6D2/T3D1 Fr=5 Kiln Drying Rate: Naturally dries slowly
Drying Defects: Slight surface checking, Slight twist/warp Ease of Drying: Variable results. Tree Identification: Bole/stem form is straight Comments: General finishing qualities are rated as good Treatment against ultra-violet fading has been suggested since the wood turns gray-brown upon exposure to sunlight. A treatment with Armorall, the car finish product, under lacquer is reported to maintain the original color wellWorking the wood with dull cutting tools may cause gum exudation Blunting Effect: Blunting is rated as moderate to severe Boring: Fairly easy to very easy Carving: Fairly Easy to Very Easy Cutting Resistance: Moderate to fairly difficult to saw Gluing: Easy to glue
Mortising: Fairly Easy to Very Easy Moulding: Fairly Easy to Very Easy Movement in Service: Fairly Easy to Very Easy Nailing: Pre-boring recommended, Very Good to Excellent Planing: Respond poorly to ordinary tools Resistance to Impregnation: Sapwood is permeable Resistance to Splitting: Poor
Response to hand tools: Response to hand tools is fair Routing recessing: Fairly Easy to Very Easy Sanding: Good sanding finish Veneering qualities: No steaming needed during bolt preparation., Suitable for slicing Steam bending: Fairly well defined
Turning: Good results
Polishing: Surface Preparation; Staining: Takes finishes rather well ;
