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.

Hardness main types of hardness measurements: "scratch", "indentation", and "rebound". Within each of these classes of measurement there are individual measurement scales. For practical reasons conversion tables are used to convert between one scale and another. Scratch hardness is the measure of how resistant a sample is to fracture or permanent plastic deformation due to friction from a sharp object. The principle is that an object made of a harder material will scratch an object made of a softer material. When testing coatings, scratch hardness refers to the force necessary to cut through the film to the substrate. The most common
