Common uses: Balusters, Barge fenders, Bedroom suites, Boat building (general), Boxes and crates, Building construction, Building materials, Cabinetmaking, Carvings, Casks, Chairs, Chests, Concealed parts (Furniture), Construction, Crossties, Decorative plywood, Decorative veneer, Desks, Dining-room furniture, Docks, Dockwork, Domestic flooring, Dowell pins, Dowells, Drawer sides, Excelsior, Figured veneer, Fine furniture, Floor lamps, Flooring, Flooring: industrial heavy traffic, Furniture , Furniture components, Furniture squares or stock, Furniture, Harbor work, Hatracks, Interior construction, Joinery, Kitchen cabinets, Light construction, Marine construction, Piling, Plywood, Poles, Railroad ties, Toys, Turnery, Vats, Veneer Product sources: The ITTO reports that timber production from the species is not regular. It is exported only in low volumes. Environment profile: Vulnerable in parts of its natural habitat Tree size: Tree height is 40-50 m
Colors: the heart isYellow to golden-yellow to orange, Yellowish tanand the sapwoodWhite, Yellow.The grain isStraight, the textureMediumand the lusterLustrous
Natural durability: Susceptible to insect attack, Very little natural resistance Silica Content: Siliceous
Kiln Schedules: Drying (speed) is fast
Drying Defects: Moderate twist/warp
Ease of Drying: Requires a controlled drying to prevent shrinkage
Tree Identification: Bole/stem form is straight Boring: Requires strong hold to prevent chipping of exit holes
Cutting Resistance: Cutting Resistance with green wood is easy
Gluing: Glues well Mortising: Support material during mortising to prevent break out. Moulding: Good finishing Movement in Service: Good finishing Nailing: Holds nails well, Pre-boring recommended Planing: Planes well, to a good finish Resistance to Abrasion: Fair resistance
Resistance to Impregnation: Sapwood is permeable Resistance to Splitting: Satisfactory Response to hand tools: Fairly Difficult to Difficult to Work Veneering qualities: Easy to cut, Suitable for slicing Steam bending: Good
Screwing: Good screw holding properties, Screwing yields good results;
Polishing: Very Good to Excellent;
Max. crushing strength = high Density (dry weight) = 46-52 lbs/cu. ft. Shrinkage, Tangential = large Shearing strength (parallel to grain) = medium Density (dry weight) = 38-45 lbs/cu. ft. Bending strength (MOR) = high Shrinkage, Tangential = very small Shrinkage, Tangential = small Shrinkage, Radial = small Shrinkage, Radial = moderate Shrinkage, Radial = fairly large Modulus of Elasticity (stiffness) = low Modulus of Elasticity (stiffness) = high Hardness (side grain) = soft Density (dry weight) = 53-60 lbs/cu. ft. Bending strength (MOR) = very high Bending strength (MOR) = medium Shrinkage, Radial = very small Shrinkage, Radial = large Modulus of Elasticity (stiffness) = medium Density = very high Compression strength (parallel to grain) = very high Bolza, E., Keating, W.G.,1972,African Timbers - the Properties, Uses and Characteristics of 700 Species,C.S.I.R.O.
