Asia Countries of Distribution  [VIEW MAP] Malaysia, Philippines Environmental Profile Abundant/Secure Status unknown in some areas due to inadequate information Rare in many parts of its range Data source is World Conservation Monitoring Center Rare within its natural habitat in Taiwan. Status unknown in the Malay Peninsula and the Philippines Distribution Overview The genus Turpinia is composed of about a dozen species that are distributed in the tropical regions in southeast Asia, the West Indies, Mexico, Central America, and in South America to Ecuador and northern Peru. Heartwood Color Brown Brown Clearly distinct from the lighter colored sapwood Grain Even Straight Generally straight, but not always Texture Coarse Fine to medium Natural Durability Perishable Non-durable Non-resistant to termites Very low natural resistance to decay and attack by termites Odor Has an odor No specific smell or taste Drying Defects Splitting Checking Collapse Distortion Ease of Drying Rapidly Thick Stock Requires Care Moderately Difficult to Difficult Blunting Effect Moderate Boring Fairly difficult to very difficult Carving Fairly Difficult to Very Difficult Cutting Resistance Fairly Difficult to Very Difficult to saw Gluing Fair to Good Results Fairly Easy to Very Easy Mortising Fairly Difficult to Very Difficult Moulding Fairly Difficult to Very Difficult Movement in Service Fair to Good Stability - Medium Movement Nailing Fair to Good Results Fairly Easy to Very Easy Planing Fairly Difficult to Very Difficult Poor to Very Poor Results Resistance to Impregnation Permeable sapwood Resistant heartwood Resistant sapwood Response to Hand Tools Fairly Difficult to Difficult to Work Responds well to ordinary machine tools in most operations Screwing Fair to Good Results Turning Fair to Good Results Fairly Difficult to Very Difficult Steam Bending Poor to Very Poor Results Polishing Very Good to Excellent Results Staining Fair to Good Results Fairly Easy to Very Easy Very Good to Excellent Results Strength Properties Soft Dents or scratches easily Compression strength (parallel to grain) = low Bending strength (MOR) = medium The species has medium bending strength in the air-dry condition (about 12 percent moisture content). It is closer in strength to Mahogany than either Teak or White oak, which have higher bending strength. It also does not wear well, and mars easily Numerical Data Item Green Dry English Bending Strength 5645 8879 psi Crushing Strength 420 657 psi Hardness 463 lbs Maximum Crushing Strength 2634 4404 psi Shearing Strength 1039 psi Static Bending 3512 5938 psi Stiffness 872 1054 1000 psi Toughness 172 inch-lbs Specific Gravity 0.35 0.36 Item Green Dry Metric Bending Strength 396 624 kg/cm2 Crushing Strength 29 46 kg/cm2 Hardness 210 kg Maximum Crushing Strength 185 309 kg/cm2 Shearing Strength 73 kg/cm2 Static Bending 246 417 kg/cm2 Stiffness 61 74 1000 kg/cm2 Toughness 198 cm-kg References Lauricio, F.
