Afrormosia closely resembles teak and is so often used as a teak substitute that it is sometimes referred to as African teak. But the wood is prized for for more than simply its resemblance to teak - it is also valued for character and properties all its own.
Afrormosia trees grow in West Africa - primarily Ghana and the Ivory Coast. Its heartwood is yellow brown but darkens on exposure. The trees are described as "gregarious," thriving in wet or dry conditions. According to Herbert Edlin, author of The Illustrated Encyclopedia of Trees, afrormosia has the "appearance of a fine-grained teak but lacks the slightly oily finish. It does not bleach on exposure (like teak) but darkens with time." Edlin also writes that it shows little movement after seasoning, is stronger and harder than most teaks, and is less prone to blunting steel tools.
Afrormosia is suitable for many applications, among them veneers, paneling, boat building, stairs, flooring, high-end joinery, cabinetmaking, farm implements, decks and marine piling.
A Wood By Any Other Name...
Andrew Poynter of A & M Wood Specialty Inc., Cambridge, ONT, said afrormosia has traditionally been a very popular wood in the United Kingdom because it is easily imported from West Africa. Poynter said that he gets a few calls for the lumber, but his company does not stock or sell large quantities of the wood. "We recently did a couple of flooring jobs with it in the United States," Poynter said. "I also have seen the wood referred to as java teak."
Poynter said that afrormosia has a ribbon stripe on quarter-sawn material and can be "somewhat difficult to machine - especially when quarter sawn. It has a less dulling effect on cutting surfaces than teak, because afrormosia does not contain the silica that teak does," Poynter said. Poynter added that good lengths and widths are available in the timber.
Albert Constantine Jr. writes of another common name for afrormosia in his book Know Your Woods. "The bark is blotched with red and orange, which is why it has acquired the common name of red-bark."
Constantine writes that after afrormosia has been cut for some time, "it resembles Burma teak, changing from a yellow color to a warm brown with exposure to air and light." The main difference between teak and afrormosia, according to Constantine, is that "after repeated scrubbings, afrormosia remains a dark color. It is useful for decking."
Durability and Versatility
Sawdust from afrormosia can be an eye irritant, according to the U.S. Department of Agriculture's book Tropical Timbers of the World. The USDA recommends working the wood in conditions with good ventilation.
For drying, the USDA Forest Service recommends a kiln schedule T10-D5S for 4/4 stock and T8-D4S for 8/4 stock. The wood dries slowly with little degrade except for a slight warp, according to the Forest Service.
Afrormosia trees are considered "medium tall" for the forests of West Africa. The boles can be irregular but are clear to 90 or 100 feet.
