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,
Indentation hardness used to quantify material characteristics at smaller scales. Measuring mechanical properties for materials, for instance, of thin films, can not be done using conventional uniaxial tensile testing. As a result, techniques testing material "hardness" by indenting a material with a very small impression have been developed to determine to estimate these properties. Hardness measurements quantify the resistance of a material to plastic deformation. Indentation hardness tests compose the majority of processes used to determine material hardness, and can be divided into two classes: "microindentation" and "macroindentation" tests. Microindentation tests typically have forces less than . Hardness, however, cannot be considered
