Heartwood resistance to decay is negligible Odor No specific smell or taste Toxicity Some toxic effects Drying Defects Distortion The material air-seasons rapidly with little degrade. It also kiln dries with only slight checking and twisting. Some discoloration may occur during seasoning due to mold growth Ease of Drying Seasons rapidly with little degrade Easy Careful stacking is recommended to minimize degrade. Tree Identification Bole/stem form is buttressed Bole/stem form is straight Bole/stem form is cylindrical Tree Size Trunk diameter is 100-150 cm Tree height is 40-50 m Bole length is 20-30 m Sapwood width is 5-10 cm Tree height is 10-20 m Tree height is 20-30 m Tree height is 30-40 m Sapwood width is 0-5 cm Tree height is 50-60 m Bole length is 10-20 m Trunk diameter is 150-200 cm Trunk diameter is 200-250 cm Trunk diameter is 250-300 cm Trunk diameter is 300-350 cm Comments Reaction with Metals - The timber tends to develop stains when it comes in contact with iron and iron compounds under moist conditions. Boring Fairly easy to very easy Cutting Resistance Easy to saw Cutting Resistance with dry wood is easy Gluing Fairly Easy to Very Easy Satisfactory gluing properties Moderate gluing properties Mortising Fairly Easy to Very Easy Moulding Fairly Easy to Very Easy A cutting angle of 20 degrees has been suggested to reduce fuzzy surfaces during moulding operations Movement in Service Excellent Stability - Small Movement Unstable, tends to move considerably after manufacture Nailing Fairly Easy to Very Easy Good nailing properties Easy to nail Planing Fairly Easy to Very Easy Planes well, to a good finish Some grain tearing may occur during planing of quartersawn surfaces. A reduced cutting angle of 15 to 20 degrees has been suggested. Resistance to Impregnation Resistant heartwood Resistant sapwood Heartwood is moderately resistant Resistance to Splitting Poor Response to Hand Tools Easy to Work Fairly Difficult to Difficult to Work Easy to machine Response to hand tools is good Screwing Takes screws well Turning Fairly Easy to Very Easy Steam Bending Good Polishing Fair to Good Results Satisfactory results Staining Fair to Good Results Satisfactory staining qualities Varnishing Satisfactory Strength Properties Bending strength (MOR) = very high Shrinkage, Tangential = fairly large Shrinkage, Radial = moderate Max. crushing strength = high Density (dry weight) = 38-45 lbs/cu. ft. Bending strength (MOR) = high Shrinkage, Volumetric = fairly large Shrinkage, Tangential = moderate Shrinkage, Tangential = large Shrinkage, Radial = small Shrinkage, Radial = fairly large Shearing strength (parallel to grain) = high Modulus of Elasticity (stiffness) = high Bending strength (MOR) = medium Numerical Data Item Green Dry English Bending Strength 13734 20519 psi Density 45 lbs/ft3 Maximum Crushing Strength 6170 9574 psi Shearing Strength 2542 psi Stiffness 2005 2302 1000 psi Specific Gravity 0.72 Weight 44 31 lbs/ft3 Radial Shrinkage 4 % Tangential Shrinkage 8 % Volumetric Shrinkage 13 % Item Green Dry Metric Bending Strength 965 1442 kg/cm2 Density 721 kg/m3 Maximum Crushing Strength 433 673 kg/cm2 Shearing Strength 178 kg/cm2 Stiffness 140 161 1000 kg/cm2 Specific Gravity 0.72 Weight 705 496 kg/m3 Radial Shrinkage 4 % Tangential Shrinkage 8 % References Bolza, E., Keating, W.G.,1972,African Timbers - the Properties, Uses and Characteristics of 700 Species,C.S.I.R.O.
