COMMON NAMES HEIGHT/WEIGHT PROPERTIES People looking for a mahogany-like wood sometimes find what they seek in andiroba, a wood that grows throughout tropical South America, Central America and the Caribbean. Andiroba's heartwood varies in color from reddish brown to dark red brown with texture and pore size comparable to the Swietenia mahoganies, although andiroba is heavier than mahogany.
People looking for a mahogany-like wood sometimes find what they seek in andiroba, a wood that grows throughout tropical South America, Central America and the Caribbean. Andiroba's heartwood varies in color from reddish brown to dark red brown with texture and pore size comparable to the Swietenia mahoganies, although andiroba is heavier than mahogany.
In the countries where it grows, plain andiroba has some utilitarian uses such as frame construction, boat and ship decking and plywood. It is also used for furniture, cabinets, flooring, turnery and millwork. The finely figured material is also a popular choice for decorative veneers and architectural paneling.
Widespread Range, Varied Names
Andiroba is the term that seems to dominate the U.S. market. However, "because of the variation in the character of the wood it has been suggested that the name andiroba should be used for the finer-textured, denser material and the name crabwood for the coarser-textured wood of medium density," according to "World Timbers."
The authors of "The Encyclopedia of Wood" believe that the widespread distribution of andiroba in tropical America accounts for the wide variety of names. The wood is also known as krappa in Suriname; figueroa in Ecuador; carapote in Guadeloupe; carapa in Guiana; camacari in Brazil and masabalo in Columbia. Other names include cedro marcha, carapa, crabwood and tangare, according to "The Encyclopedia of Wood," but these names are also applied to the related species Carapa nicaraguensis, whose properties are considered "generally inferior to those of C. guianensis."
A Dramatic Look
Andiroba may dull tools and sandpaper, according to reports from customers, says Jim Dumas of Certainly Wood of East Aurora, NY. "It is a coarse wood that isn't terribly dense, but there is something about it that makes woodworking slightly tougher than mahogany," he says. "For our purposes, the highly figured material can be slightly harder to roll and put in packages because it can be a tiny bit brittle."
Dumas says customers seem to prefer highly figured andiroba over plain. "We see the most activity with the highly figured material that can have what I describe as an electric look. In photos, figured andiroba leaps off the page," says Dumas.
The Durability Debate
Other sources, however, list possible uses for the wood as boat construction and ship's decking. Part of the reason for different reports on durability may be the fact that the wood is usually straight-grained but can be interlocked, and its texture can vary from coarse to fine, depending on log and country of origin.
Experts agree that andiroba needs to be seasoned slowly. In the book "World Woods in Color," William A. Lincoln cautions that "drying must be carried out slowly as there is a marked tendency to split, check, twist or collapse in the early stages. A low temperature with high humidity schedule is best for kilning."
