Ipé Species Information
 
Introduction Ipé is a member of the lapacho group of the genus Tabebuia. The timbers in this group are noted for their great strength and durability and are characterised by the presence of a yellowish powder (lapachol compound) in the vessels.
Distribution The tree is found in Trinidad, Grenada, and St Vincent of the Lesser Antilles, and on the continent from Mexico through Central America and into South America to southern Brazil, including Colombia, Bolivia, Peru, Paraguay, Venezuela, Guyana and Surinam.
The Tree T. serratifolia is a canopy tree, unbuttressed or with low buttresses, about 37.0m high and a diameter of about 1.0m, although in some parts of its range diameters of about 2.0m are found. Clear cylindrical boles 15.0m to 18.0m are common.
The Timber The heartwood is yellowish green when first cut, turning a light to dark olive-brown with lighter or darker streaks. The sapwood is distinct, greyish-white in colour, and 38mm to 88mm wide. The texture is fine; the grain is straight to occasionally irregular, and the lustre is low to medium. Pores in the heartwood, which appear as fine yellow dots, are filled with a yellowish powder (lapachol), and appear on longitudinal surfaces as yellow lines. The wood is cold to the touch and often appears oily; very fine ripple marks are usually present.
Drying Despite its relatively high density, ipé is a fairly easy wood to dry. It dries rapidly with slight warping, cupping, twisting, end and surface checking occurring. A slow drying kiln schedule is recommended.
Strength The wood is hard, tough and strong, and compares favourably with greenheart.
Working Qualities Difficult - Ipé is moderately difficult to work especially with hand tools, and has a blunting effect on cutting edges.A good finish is usually obtained when planing or moulding plain-sawn material, but a cutting angle of at least 15° is recommended to eliminate chipping of quarter-sawn stock. The timber stains and polishes well and requires little grain-filler, but pre-boring is required before nailing to prevent splitting and bending of nails.

Cumaru Species Information
Wood type Hardwood
Environmental Sourced from well-managed forests with government accreditation
Distribution Naturally distributed throughout northern South America and Central America, the tree has been widely cultivated in Mexico and the West Indies, particularly in Jamaica. Although the primary aim of cultivation has been vested in the collection of the tonka beans produced by the tree, commercially valuable as a substitute for vanilla for cocoa production and for flavouring snuff and tobacco, the timber is also an excellent material.
The Tree A fairly large, unbuttressed tree, 24.0m to 36.0m high, with a diameter of 0.5m to 0.75m but are often larger on the best sites. The boles are clean and cylindrical, and generally 18.0m to 24.0m long.
The Timber The heartwood is reddish-brown or purplish-brown, with light yellowish-brown or purplish streaks when freshly cut, turning to a variegated reddish and yellowish-brown after drying, but on exposure to light assuming a uniform yellowish-brown or light brown colour. The sapwood is about 50mm wide, distinct from the heartwood and yellowish-brown in colour. The wood has a waxy or oily feel, a fine texture, and irregular and often interlocked grain. It is an extremely hard and heavy wood.
Drying Considering its density, the wood is relatively easy to dry. It tends to surface check if dried rapidly, but moderate to slow drying rates should reduce this tendency. Thicker sections are at risk from casehardening.
Strength The strength of the green wood closely resembles that of greenheart, except in tension across the grain and side hardness, in which cumaru is superior. Air dried wood is much stronger than green wood except for an appreciable reduction in cleavage resistance and tensile strength across the grain. In general it is superior to white oak in all properties except cleavage resistance.
Working Qualities Difficult - Cumaru is a heavy, hard, and tough wood which makes it rather difficult to work, but with sharp tools it saws and bores cleanly, and when severely interlocked grain is absent, planes and finishes to a smooth surface. It takes a high polish, but glues poorly.

Yellow Balau Species Information

Introduction The hard, heavy timber species of shorea occurring in South East Asia are grouped under common trade names peculiar to the area. Thus selangan batu is the name used in Sabah, Brunei and Sarawak, while balau is used to describe the heavy Malaysian species.
Drying Difficult to dry, slow drying with a tendency to end split, warping is variable.
Strength All the species mentioned have hard, heavy and strong timbers with strength properties similar to those of greenheart.
