African Padauk

African Padauk is the trade name for the wood of Pterocarpus soyauxii, a large legume tree of the tropical rainforests of central and west Africa. It is one of several African Pterocarpus species sold as "padauk," and by far the most common in the international timber trade, valued above all for its startling color.

The tree reaches 100 ft or more in the forests of Nigeria, Cameroon, Gabon, and the Congo basin. Freshly cut the heartwood is a vivid orange to blood-red, and the sample shown is characteristic: a reddish-orange to deep red board with medium, slightly interlocked grain. Padauk is dense, hard, and naturally durable, which together with its unmistakable color makes it a favorite for both fine work and heavy-duty use.

The heartwood is the wood's signature: a bright orange-red to vivid vermillion or deep blood-red when freshly worked, often with darker red or purple-brown streaking. The pale straw-colored sapwood is clearly demarcated. Over time and with light exposure the vivid orange-red mellows and darkens toward a warm reddish-brown or muted brown-purple, so the fresh color is not permanent unless protected.

Grain is straight to interlocked — the sample shows the typical medium interlocked pattern — with a coarse but even texture and a good natural luster. It is a heavy wood, averaging around 45 lb/ft³ (about 720 kg/m³) dried, and rates roughly 1,970 lbf on the Janka scale, firmly in the hard range and well above domestic oaks and maples. Natural durability is excellent: the heartwood is rated very durable, highly resistant to decay and to termite and insect attack, and it is also dimensionally very stable in service.

Padauk's color and durability suit it to a wide range of work. It is popular for fine and contemporary furniture, cabinetry, and architectural accents where the vivid red is wanted as a highlight, and its hardness and stability make it a strong flooring and decking material. Its rot resistance also lends it to boatbuilding and exterior joinery.

It is a favorite of turners, carvers, and small-project makers, appearing in bowls, boxes, knife and tool handles, pens, and inlay and marquetry work where a splash of red is needed. Padauk is also used for musical instruments — notably drum shells, xylophone and marimba bars, and fingerboards — and its historic use as a source of a red dye (from the related "barwood"/"camwood" species) accounts for some of its trade names.

Padauk has a reputation as an easy tropical hardwood to work. Despite its density it machines, turns, and carves well, planes to a clean surface, and its interlocked grain causes only minor tearout with sharp tooling. It glues, holds fasteners, and takes a fine finish, though the coarse open pores may need filling for a fully smooth surface. Pre-boring is advisable near ends because of its hardness.

Because the fresh red color fades with UV exposure, makers who want to preserve the vivid tone use a UV-inhibiting finish and keep the piece out of strong sunlight. Note that the wood's natural resins can bleed color into adjacent light-colored woods and can react with iron, so use appropriate glue-ups and finishes.

Caution: padauk dust is a known irritant and sensitizer. Fine dust can irritate the eyes, skin, and respiratory tract, and reported reactions include skin and asthma-like effects; the vivid pigment also stains skin and clothing readily. Use dust collection and a respirator when sanding. Pterocarpus soyauxii is not currently CITES-listed, though some other Pterocarpus species (such as the rosewood-type P. tinctorius and P. santalinus) are restricted.

African Padauk is one of the more widely available and affordable brightly colored exotic hardwoods. It is imported regularly to North America and Europe as lumber, turning blanks, and craft stock in a good range of sizes, and its cost sits in the low-to-moderate tier for an imported tropical hardwood — cheaper than most true rosewoods and generally accessible to hobbyists.

On sustainability, Pterocarpus soyauxii is not listed on any CITES appendix and is not currently flagged as threatened, so it moves in trade more freely than the restricted rosewood-class padauks. As with all tropical timber, responsibly sourced or FSC-certified stock is preferable given ongoing pressure on central African forests. Buyers should confirm the exact species, since several African and Asian "padauks" share the trade name.
