Asia) Distribution overview: Brazil (Bahia, Espto Santo, Minas Gerais, Rio de Janeiro, SPaulo). The species is encountered equally in primary and secondary formations, occurring on soils of low natural fertility, deep clay and clay-sand soils with good drainage. It is able to tolerate dry conditions. Common uses: Bedroom suites, Billiard-cue butts, Boat building (general), Bobbins, Boxes and crates, Brush backs & handles, Building materials, Cabinetmaking, Chairs, Chests, Decorative plywood, Decorative veneer, Desks, Dining-room furniture, Drawer sides, Drum sticks, Figured veneer, Fine furniture, Flooring, Furniture , Furniture, Handles, Handles: woodworking tools, Heavy construction, Interior construction, Joinery, Kitchen cabinets, Living-room suites, Marquetry, Mine timbers, Musical instruments , Musical instruments, Musical instruments: piano, Office furniture, Organ pipes, Paneling , Paneling, Piano keys, Pianos , Picker sticks, Plywood, Poles, Radio - stereo - TV cabinets, Railroad ties, Shade rollers, Shafts/Handles, Shuttles, Sounding boards, Specialty items, Spindles, Spools, Sporting Goods, Stencil & chisel blocks, Sucker rods, Tool handles, Turnery, Umbrella handles , Vehicle parts, Veneer: decorative Product sources: Brazillian rosewood is scarce in the more accessible areas because of over-harvesting, but some timber from the species is available from environmentally responsible sources. Supplies of Brazilian rosewood are very limited because of shortages, making it quite expensive. Related species are available on the market as substitutes for true Rosewood. Environment profile: Extinct, Endangered, Vulnerable, or Rare within its range Tree size: Trunk diameter is 200-250 cm
Colors: the heart isYellow, Yellow to golden-yellow to orangeand the sapwoodWhite to yellow, Yellow.The grain isWeak figure, the textureMedium to coarseand the lusterMedium
Natural durability: Susceptible to insect attack, Very durable Odor: May have a distinctive taste Kiln Schedules: UK=C US=T3C2/T3C1 Fr=3 Kiln Drying Rate: Rapid Drying Defects: Slight end splitting, Slight surface checking Ease of Drying: Requires slow and careful seasoning to prevent degrade. Tree Identification: Bole/stem form is misshapen Comments: Generally strong and durable High waste factor Since they are usually hollow. Usable volume may be reduced considerably after the undesirable sapwood is removed. Ironically, old trees with defective stems are reported to yield the most attractive material. Brazillian rosewood is far superior in hardness than any of the native N. American hardwoods used in furniture manufacturing. Rosewood is also the primary choice as a tonewood for the highest quality stringed musical instruments Blunting Effect: Moderate Boring: Vary from difficult to easy Carving: Fairly Difficult to Very Difficult Cutting Resistance: Moderate to saw Gluing: Satisfactory gluing properties Mortising: Fairly Difficult to Very Difficult Moulding: Poor to Very Poor Movement in Service: Poor to Very Poor Nailing: Pre-boring recommended, Very Good to Excellent Planing: Fairly Difficult to Very Difficult Resistance to Impregnation: Resistant sapwood Response to hand tools: Responds Readily Routing recessing: Fairly Difficult to Very Difficult Veneering qualities: Suitable for slicing
Steam bending: Very good
Screwing: Possible if prebored, Very Good to Excellent Results; Turning: Good results
Polishing: Very Good to Excellent; Staining: Very Good to Excellent;
