Wood Technical Fact Sheet
Peroba De Campos
Other Common Names: lpe peroba, Peroba, Peroba branca, Peroba manchada (Brazil).
Distribution: Coastal forests of eastern Brazil ranging from Bahia to Rio de Janeiro.
The Tree: The tree attains a height of about 130 ft and diameters to 60 in.; boles are symmetrical and clear to 90 ft.
General Characteristics: Heartwood light olive, with a yellowish, greenish, or reddish hue, sometimes indistinctly striped; sharply demarcated from the white or yellowish sapwood. Texture is fine; fairly lustrous; grain commonly interlocked with a narrow stripe or roey figure; without distinctive odor or taste. Fine dust produced in machining causes skin irritations in some workers.
Weight: Basic specific gravity (ovendry weight/green volume) 0.60; air-dry density 46 pcf.
Mechanical Properties: (2-cm standard)

Janka side hardness 1,600 lb at 12% moisture content. Amsler toughness 327 in.-lb. 15% moisture content (2-cm specimen).
Drying and Shrinkage: Reported to dry readily with negligible splitting. Warp not generally serious though it may become severe in thin stock with irregular grain. Kiln schedule T3-D2 is suggested for 4/4 stock and T3-D1 for 8/4. Shrinkage green ovendry: radial 3.8%; tangential 6.6%; volumetric 10.5%.
Working Properties: The wood is reported to machine easily but care is needed in planing quartered surfaces. Easy to glue and finish. As noted, may cause dermatitis in some workers.
Durability: The heartwood is rated very durable in resistance to attack by decay fungi.
Preservation: Resistant to preservative treatments.
Uses: Fine furniture, interior joinery, decking and flooring, vats and tanks for foodstuffs, decorative veneers.
