"Mimosa tenuiflora" is a very good source of fuel wood and works very well for making posts, most likely because of its high tannin content (16%), which protects it from rot. Due to its high tannin content, the bark of the tree is widely used as a natural dye and in leather production. It is used to make bridges, buildings, fences, furniture and wheels. It is an excellent source of charcoal and at least one study has been done to see why this is the case.
