Common Name: Burada
Scientific Name: Parinari campestris
Wood Description: Burada, from Parinari campestris, has a heartwood that is light brown to pinkish-brown, rarely yellowish-brown. It can also be gray brown, yellow brown, or yellowish pink brown when freshly cut, often turning a deep orange brown. The sapwood is similar in color to the heartwood or somewhat lighter and not clearly defined. The texture is fine, though scattered pores are coarse. The grain is generally straight, sometimes slightly interlocked. Luster is mostly low. It is without a distinctive odor or taste.
Physical Properties: Burada is a moderately dense wood. Its basic specific gravity (oven-dry weight/green volume) varies with species from 0.64 to 0.72. Air-dry density is 50 to 55 pcf (approximately 801-881 kg/m³). The density at 12% moisture content is 890 kg/m³. The Janka side hardness is 1,830 lb at 12% MC and 1,270 lb for green wood. The Forest Products Laboratory toughness averages 157 in.-lb. Shrinkage from green to oven-dry is radial 5.9% and tangential 10.0%, with volumetric shrinkage of 14.6%. The wood air-dries rapidly with only slight checking, but warp is moderate. Silica content up to about 2.0% is reported.
Mechanical Properties: Burada exhibits good mechanical strength. Its bending strength (Modulus of Rupture, MOR) is 20,120 psi at 12% MC. The modulus of elasticity (MOE) is 2,610 (1000 psi) at 12% MC. Crushing strength is 10,260 psi at 12% MC. These properties align with its use in heavy construction.
Uses Burada is suitable for marine construction, especially when continuously submerged to avoid decay fungi. It is also used for ship keels, railroad crossties (treated), heavy construction, and flooring. Other uses include general carpentry, millwork, furniture, turnery, and utility plywood.
