About Teak

Drying and Shrinkage: Seasons slowly but with little or no degrade, large variations in drying rates reported. Kiln schedule T10-D4S is suggested for 4/4 stock and T8-D3s for 8/4. Srinkage green to ovendry: radial 2.5%; tangential 5.8%; volumetric 7.0%. Movement in service is rated as small. High resistance to water absorption.

Working Properties: Easily worked with both hand and machine tools and dresses to a very smoth finish if tools are kept sharp; glues moderately well despite its oily nature. Blunting of cutters can be rather severe. As noted, may cause dermatitis in some individuals.

Durability: Heartwood is rated as very durable with respect to decay fungi and termites; not immune to marine borers.

Preservation: Heartwood extremely resistant to preservative treatments, sapwood also low of permeability.

Uses: Shipbuilding, joinery, furniture, flooring, carving, cabinetwork, paneling, turnery, tanks, and vats, fixtures requiring high resistance to acids.

Tectona grandis Teak Family: Verbenceae Other Common Names: Kyun (Burma), Teck (French), Teca (Spanish). Distribution: Native to India, Burma, Thailand, Indochina, including Indonesia, particularly Java. Extensively cultvated in plantations within its natural range as well as in tropical areas of Africa and Latin America. On favorable sites, may reach 130 to 150 ft in height with clear boles to 80 to 90 ft; trunk diameters usually 3 to 5 ft; older trees fluted and buttressed. General Charateristics: Heartwood dark golden yellow, turning dark brown with exposure, often very variable in color when freshly machined showing blotches and streaks of various shades; sapwood pale yellowish, demarcated. Grain straight, sometimes wavy; texture coarse, uneven (ring porous); dull with an oily feel; scented when freshly cut. Dust may cause skin irritations. Silica content variable, up to 1.4% is reported. Weight: Basic specific gravity (ovendry weight/green volume) 0.55; air-dry density 40 pcf. Mechanical Properties: (First set of data based on the 2-cm standard; second and third sets on the 2-in. standard; third set plantation-grown in Honduras.)
