Supplies in the lumber form are plentiful in a wide variety of sizes. The wood is also available in plywood form from many suppliers at a moderate price Environment profile: Status has not been officially assessed
Tree size: Trunk diameter is 250-300 cm
Colors: the heart isRed, Reddish brownand the sapwoodWhite to yellow, Yellow.The grain isWavy, the textureUniformand the lusterSlightly lustrous
Natural durability: Resistant to termites, Susceptible to attack from powder post (Lyctid & Bostrychid) beetles Odor: No specific smell or taste
LightInduced Color Change: Darker
Kiln Schedules: Kiln Drying Rate (in days) is rapid Kiln Drying Rate: Rapid (<10 days for boards < 32 mm, to <30 days for boards >= 63 mm)
Drying Defects: Slight twist/warp, Splitting Ease of Drying: Fairly Easy Tree Identification: Bole/stem form is straight Comments: Abnormal Wood TissueAbnormal wood tissue in the form of tension wood may be present.General finishing qualities are rated as good The timber is generally similar in strength and other properties and is used for the same purposes as other African mahoganies, K. ivorensis and K. anthotheca . Blunting Effect: Medium effect
Boring: Responds readily to boring operations Carving: Good carving properties
Cutting Resistance: Easy to saw Gluing: Glues well Mortising: Moderately easy to mortise Moulding: Moulding ease is moderate Movement in Service: Moulding ease is moderate Nailing: Nails hold poorly
The nailing properties of this timber are variable, and are believed to be generally poor. Pre-boring is advised, especially when nailing areas close to the edge of backsawn boards.
Planing: Planes well, to a good finish Resistance to Impregnation: Sapwood is moderately resistant Resistance to Splitting: Poor
Response to hand tools: Easy to machine Routing recessing: Routing is easy
Routing and recessing qualities are rated as good in straight grain material
Sanding: Good sanding qualities
Veneering qualities: Suitable for slicing, There is slight to moderate drying degrade and the potential for buckles and splits
Screwing: Pre-Boring suggested before screwing
; Turning: Turns fairly well
Polishing: High polish;
