This week's wood, Goncalo Alves is definitely, no plain jane. I really like the look of this one.
Goncalo Alves, scientifically known as Astronium graveolens is a member of the Anacardiaceae family.
Goncalo Alves is a large tree, 120 feet tall and 24-40 inches in diameter. It grows in South America, from Mexico Columbia, Venezuela, Brazil, Honduras and Equador. The lumber from Hondras and Venezuela, is heavier than that from Brazil and Columbia. The heavier variety has a specific gravity of .84 while the lighter is .75. That is a fairly big difference in weight.
When freshly cut, Goncalo Alves heartwood is russet brown, orange brown, or reddish brown to red with narrow to wide irregular stripes of medium to very dark brown. After exposure it becomes brown, red, or dark reddish brown with nearly black stripes. The dingy grayish or brownish-white sapwood, 2 to 4 in. wide, is sharply demarcated. The wood often has a striking figure caused by irregular dark longitudinal bands.
Goncalo Alves has a Janka Hardness of 2160. As a reminder, hard maple is rated at 1450 on this scale.
As always photgraghs of outstanding examples of this species are welcomed. Please feel free to add any information that you may have, or correct anything you feel I got wrong.
