Tigerwood

Tigerwood, also widely known as Goncalo Alves (Astronium graveolens or A. fraxinifolium), is a premium South American hardwood famous for its striking, tiger-like striped appearance. In 2026, it is highly valued for both luxury interior furniture and heavy- duty exterior decking due to its extreme durability and natural oils.

Color Range

Fresh timber typically features a light golden-brown to vibrant reddish- orange background. Background colors naturally deepen and redden over time with light exposure, which can slightly reduce the contrast of the dark stripes.

Grain

Bold, irregular longitudinal streaks in dark brown to near-black run through the wood, creating the characteristic "tiger" pattern.

Texture

It possesses a high natural luster and a "metallic" or slightly oily appearance when finished.

Strength, Stability, and Durability

Durability: It is naturally resistant to water, rot, decay, and insect attack (including termites and beetles), requiring no chemical preservatives. Stability: Once properly kiln-dried, it is dimensionally stable with very little movement or shrinkage.

Workability / Finishing

Machining: Its high density and interlocked grain can have a moderate to severe blunting effect on cutting tools. Carbide-tipped blades and bits are strongly recommended. Fastening: Due to its extreme hardness and risk of splitting, pre-drilling is mandatory for all screws and nails. Finishing: It glues easily and takes a high-gloss finish exceptionally well. For exterior use, a UV-inhibiting oil finish is required to prevent the wood from weathering to a silver-grey.
