Tigerwood –(Astronium Graveolens )
Better known on the international market as Muiracatiara or Goncalo Alves, but does have lesser known names such as Brazilian Koa or Jabillo. It cuts easy for being a dense species and has very good resistance to rot and decay. The heartwood is light brown in color with moderate to wild black streaking. Due to the color variation, there is a particular allure to furniture builders, although its uses in decking and flooring are not new. Available as both FSC and Non-FSC certified Tigerwood is kiln-dried (KD) and available as decking, flooring, dimensional lumber, E4E, S4S, RS (Rough Sawn), deck tiles, and table slabs.
