Hymenaea courbaril plasters, but at present its only use is for incense and varnish. The wood is very hard, measuring 5.6 on the Brinell scale and on the Janka scale, approximate measurements of hardness. For comparison, Douglas fir measures , white oak , and Brazilian walnut on the Janka scale. It features a tan to salmon color with black accent stripes that over time turn to a deep and vibrant red. Attribution: Hymenaea courbaril Hymenaea courbaril (courbaril and West Indian locust) is a tree common in the Caribbean, Central America, and South America. It is a hardwood that is used for furniture,
Vickers hardness test values are generally independent of the test force: they will come out the same for 500 gf and 50 kgf, as long as the force is at least 200 gf. For thin samples indentation depth can be an issue due to substrate effects. As a rule of thumb the sample thickness should be kept greater than 2.5 times the indent diameter. Alternatively indent depth can be calculated according to: When doing the hardness tests the minimum distance between indentations and the distance from the indentation to the edge of the specimen must be taken into account to avoid interaction between
