The species is considerably stronger than White oak or Teak. It is hard - harder than Teak,
Wood produced by Peroba rosa is described as hard and heavy, and is one of the highly important and general utility timbers in Brazil. It is sometimes brittle, and grain type tends to affect some strength properties, such as shock resistance which is considerably reduced in the presence of cross grain. Peroba rosa is comparable to the N. American oaks (Quercus ) in strength properties.
