Muiracatiara / Tigerwood
Species profile
The heartwood has a light orange brown colour, with an irregular pattern of black stripes, which makes it very decorative. After exposure Muiracatiara darkens quickly to orange or dark red brown. The sapwood is clearly demarcated. The grain is straight or interlocked and the texture is fine. Density at 12 % moisture content: 0.80 g/cm3.

Machining goes well, despite the high density. The surface gets very smooth with a greasy touch. The results with gluing and finishing are good. Pre-drilling is recommended. The blunting effect is fairly high; peeling is not recommended or without interest and slicing is reported to be good. Drying goes relatively easy, but must be done with care to avoid checking.

Muiracatiara is very durable to fungi and is durable to dry wood borers; sapwood demarcated (risk limited to sapwood).

Muiracatiara can be used for several applications such as:
• interior: e.g. veneer, panelling, flooring, tool handles, high class furniture, music instruments, sculpture, joinery, wood ware, sliced veneer
• exterior: e.g. panelling, boardwalks, constructions, heavy carpentry, joinery

Muiracatiara is often used because of the decorative appearance, but also due to the typical hardwood properties (durable and hard).
