Gaboon (Aucoumea klaineana)
Family: Burseraceae Common names: Acoume, Angouma, Bengouma, Cape Lomez mahogany, Combogala, Gaboon, Gaboon mahogany, Gaboon wood, Koumi, M'goumi, Mofoumou, Moukoumi, N'goumi, N'koum, N'koumi, N'kumi, Ojoume, Okoume, Ongoumi, Uume, Zouga Distributed in: Congo, Equatorial Guinea, Gabon (Africa) Distribution overview: The distribution of Okoums limited to the West and the Center of Gabon and some small surfaces in Guinea Equatoriale, in Congo and Cameroun. One finds this species between 0 and 700 meters of altitude in forests of leafy trees of plains. Aucoumea klaineana is one of the most abundant species in the Ombrophilous type of forest, in particular in old secondary forests on well drained sites. Common uses: Artificial limbs, Blockboard, Boat building (general), Boxes and crates, Building construction, Building materials, Cabinetmaking, Canoes, Carvings, Cigar boxes, Construction, Cooperages, Decorative plywood, Decorative veneer, Figured veneer, Fine furniture, Flooring, Furniture , Furniture components, Furniture, Interior construction, Interior trim, Joinery, Light construction, Millwork, Moldings, Musical instruments, Paneling , Paneling, Particleboard, Plywood corestock, Plywood, Pulp/Paper products, Tool handles, Turnery, Vats, Vehicle parts, Veneer, Veneer: decorative Product sources: The timber is rather plentiful within its growth range, but supplies, especially in the lumber form, are very limited on the U.S. Market. When available it is priced in the expensive range. 1-inch (2.5 cm) thick boards are reported to cost about US$9.00 per board foot, and veneer for marquetry costs about US$1.25 per square foot (Source - Wood and Wood Magazine, August, 1995).The ITTO reports that a fairly important source of timber. It is exported at a low but regular rate. Environment profile: Vulnerable Tree size: Trunk diameter is 250-300 cm
Colors: the heart isReddish brown, Salmon pink to light pinkish brown, or reddish brown and the sapwoodWhite to yellow, Yellow.The grain isWeak figure, the textureMedium to coarseand the lusterPronounced
Natural durability: Susceptible to marine borer attack, Very little natural resistance to decay in ground contact Odor: No specific smell or taste
Silica Content: Siliceous Kiln Schedules: UK=E US=T6D2/T3D1 Fr=5 Kiln Drying Rate: Slow (18-28 days for boards < 32 mm, to 52-84 days for boards >= 63 mm) Drying Defects: Slight twist/warp, Splitting Ease of Drying: Reconditioning Treatement Tree Identification: Bole/stem form is straight Comments: Gaboon is similar in strength to Poplar (Populus), though it splits more easilyGeneral finishing qualities are rated as good Generally weak and of low density. Blunting Effect: Moderate to severe blunting effect on tools Boring: Fairly easy to very easy Carving: Fairly Easy to Very Easy Cutting Resistance: Responds satisfactorily to cross-cutting and narrow bandsawing Gluing: Good gluing properties Mortising: Fairly Easy to Very Easy Moulding: Fairly Easy to Very Easy Movement in Service: Fairly Easy to Very Easy Nailing: Nailed satisfactorily without pre-boring , Very Good to Excellent Planing: Works fairly easily with both hand and machine tools Resistance to Impregnation: Responds poorly to perservative treatment Response to hand tools: Fairly Difficult to Difficult to Work Routing recessing: Fairly Easy to Very Easy Sanding: Very Good to Excellent Results Veneering qualities: Veneers easily, Veneers moderately easy Steam bending: Poor to Very Poor Results
Screwing: Fair to Good Results, Very Good to Excellent Results; Turning: Very Good to Excellent Results
Polishing: Very Good to Excellent; Staining: Very Good to Excellent; Varnishing: Satisfactory varnishing qualities ;
Bending strength (MOR) = low 0 Modulus of Elasticity (stiffness) = very low 0 Density (dry weight) = 23-30 lbs/cu. ft. 0 Shearing strength (parallel to grain) = very low 0 Hardness (side grain) = very soft 0 Shrinkage, Volumetric = moderate Shrinkage, Tangential = small Max. crushing strength = medium Max. crushing strength = low Bending strength (MOR) = medium Shrinkage, Radial = moderate Shrinkage, Radial = small Shrinkage, Radial = fairly large Max. crushing strength = high Density (dry weight) = 31-37 lbs/cu. ft. Shrinkage, Tangential = moderate Hardness (side grain) = soft Weak Very low stiffness Surfaces may dent or scratch easily Soft Shrinkage, Volumetric = small Shrinkage, Tangential = fairly large Low in density Hardness (side grain) = medium Density (dry weight) = 15-22 lbs/cu. ft. Crushing strength = medium Bending strength in the air-dried condition (about 12% moisture content) is medium, but lower than Mahogany, and much lower than White oak. strength properties similar to those of Poplar (Populus). It splits more easily than Poplar.
