Imbuia (Phoebe porosa)

Family: Lauraceae

Common names: Amarela, Brazilian walnut, Canella, Canella imbuia, Determa, Embuia, Embuia preta, Embuia vermelho, Embuya, Imbuia, Imbuia-amarela, Imbuia-brazina, Imbuia-clara, Imbuia-parda, Imbuia-rajada, Imbuia-zebria, Imbuya, Imported stinkwood

Distributed in: Brazil, South Africa (Africa, Latin America)

Distribution overview: The species occurs in the southern region of Brazil, particularly in the humid Araucaria forests in Parana and Santo Catarina. It is usually found at altitudes of 2500 to 4000 feet (760 to 1220 m) growing alongside Parana pine. The tree also grows in the rainforests of the States of Sao Paolo and Rio Grande do Sul

Common uses: Bedroom suites, Boat building (general), Building materials, Cabinetmaking, Carvings, Chairs, Chemical derivatives, Chests, Concealed parts (Furniture), Decorative veneer, Desks, Dining-room furniture, Domestic flooring, Door, Dowell pins, Dowells, Drawer sides, Excelsior, Factory flooring, Figured veneer, Fine furniture, Floor lamps, Flooring, Furniture , Furniture components, Furniture squares or stock, Furniture, Gunstocks, Hatracks, Interior construction, Joinery, Kitchen cabinets, Light construction, Living-room suites, Musical instruments, Musical instruments: piano, Office furniture, Paneling , Paneling, Parquet flooring, Plywood, Poles, Radio - stereo - TV cabinets, Railroad ties, Rifle stock, Rustic furniture, Sporting Goods, Stools, Sub-flooring, Tables , Turnery, Utility furniture, Vehicle parts, Veneer, Veneer: decorative, Wainscotting

Product sources: The species is considered to be one of the most important commercial species in Brazil. Indiscriminate exploitation, fueled by Imbuia's high commercial value, has drastically reduced the population of the species within its natural habitat.Local demand in Brazil is about as high as the supply, which limits the quantity exported. The timber is occasionally available in the US and England, especially in veneer form, and is priced in the medium range

Environment profile: Endangered within its natural habitat

Tree size: Tree height is 20-30 m

Colors: the heart isYellow, Yellow to golden-yellow to orangeand the sapwoodWhite to yellow, Yellow.The grain isWavy, the textureMediumand the lusterPronounced

Natural durability: Susceptible to attack from powder post (Lyctid & Bostrychid) beetles, Susceptible to attack from termites (Isoptera)

Odor: Has an odor Freshly-Cut wood has a characteristic strong, pleasant but spicy odor, which fades with time

Kiln Schedules: UK=E US=T6D2/T3D1 Fr=5

Kiln Drying Rate: Naturally dries quickly

Drying Defects: Moderate twist/warp, No surface checking

Ease of Drying: Requires careful stacking

Comments: General finishing qualities are rated as good General finishing qualities are rated as satisfactory Waste-Factor from matching is rather high because of great variation in color and grain. The veneer form of Imbuia has been suggested as a good substitute for Black walnut (Juglans nigra), and can be selected for color to match any kind of walnut.

Blunting Effect: Slight dulling effect on cutting tools

Boring: Fairly easy to very easy

Cutting Resistance: Cutting Resistance with dry wood is easy Resistance to sawing is low

Gluing: Very Good to Excellent Results

Mortising: Fairly Easy to Very Easy

Moulding: Fairly Easy to Very Easy

Movement in Service: Fairly Easy to Very Easy

Nailing: Poor to Very Poor , Very Good to Excellent

Planing: good

Resistance to Impregnation: Sapwood is permeable

Response to hand tools: Easy to machine

Veneering qualities: Veneers easily, Veneers moderately easy

Steam bending: Responds rather poorly to hand tools

Screwing: Fairly Easy to Very Easy, Very Good to Excellent Results; Turning: Good results

Painting: Fair to Good; Polishing: Satisfactory; Staining: The material takes stains and other finishes well ; Varnishing: Satisfactory ;

The bending strength of air-dried wood of the species is similar to that of Teak, which is considered to be strong. Compression strength parallel to grain, or maximum crushing strength, is medium. It is lower in this property than Teak. It is fairly hard, resisting wear, denting, and marring fairly well. The weight is high. The density is high.
