Natural durability: Susceptible to marine borer attack, Very durable Odor:
There is usually an astringent taste and a slightly sour odor
Kiln Schedules: UK=B US=T2C2/T2C1 Fr=2 Drying Defects: Slight surface checking, Slight twist/warp Ease of Drying: Timber should be stacked carefully Tree Identification: Bole/stem form is cylindrical Comments: General finishing qualities are rated as good Blunting Effect: Blunting effect on machining is severe Boring: Very good to excellent results Cutting Resistance: Yields smooth clean surfaces Mortising: Fair to Good Moulding: Fairly Easy to Very Easy Movement in Service: Fairly Easy to Very Easy Nailing: Poor to Very Poor , Possible if prebored Planing: Straight grained material yields clean surfaces Resistance to Impregnation: Sapwood is permeable Resistance to Splitting: Poor
Response to hand tools: Responds Readily Routing recessing: Fairly difficult to penetrate with preservatives Sanding: Moderately difficult to sand Veneering qualities: Moderately easy to veneer, No drying degrade. Dries flat without splitting Steam bending: Moderate
Screwing: Easy to screw, Poor to Very Poor Results; Turning: Straight grained material yields smooth surfaces
Polishing: Satisfactory; Staining: Reacts with Iron to discolour wood;
Shrinkage, Tangential = large Shrinkage, Radial = large Density (dry weight) = 61-67 lbs/cu. ft Modulus of Elasticity (stiffness) = very high Hardness (side grain) = very hard Modulus of Elasticity (stiffness) = high Max. crushing strength = very high Max. crushing strength = high Bending strength (MOR) = very high Bending strength (MOR) = high Bending strength (MOR) = medium Shearing strength (parallel to grain) = very high Shearing strength (parallel to grain) = high Toughness-Hammer drop (Impact Strength) = high Shrinkage, Tangential = moderate Shrinkage, Radial = moderate Shearing strength (parallel to grain) = medium Max. crushing strength = medium Hardness (side grain) = hard Very heavy Very hard Shrinkage, Tangential = fairly large Shrinkage, Radial = fairly large Density (dry weight) = >75 lbs/cu. ft Density (dry weight) = 67-75 lbs/cu.ft Compression strength (parallel to grain) = high Bending strength (MOR) = low The species is considerably stronger than White oak or Teak. It has exceptionally high bending strength qualities when air-dried. It is very hard, and may require special tools to process. The weight is exceptionally high, even in the seasoned condition. It is much heavier than Teak or White oak. The species has very high density.
