Muiracatiara Hardwood

If you want to make an architectural statement with your facade, Muiracatiara is the perfect type of wood for you. The colour of the heartwood is light orange-brown, with some dark brown 'veins'. This is what gives Muiracatiara its name Tigerwood! In addition to being decorative, the wood is also very durable and strong, so it can take a beating!

Durability class

Class 1.

Strength class

D40.

Applications

Muiracatiara hardwood is widely used because of its decorative appearance and typical hardwood properties (durable and strong). You will often see this hardwood in horizontal railings, facades, bridge decks and sheet piling. When planed, it becomes very slippery and has a greasy feeling.

Specific gravity

Fresh 1200-1250 kg/m3. At 12% moisture conten 750-900 kg/m3.

Colour

Red with black stripes. This type of wood is therefore called Tigerwood.

Details

The colour of the heartwood is light orange-brown, with a variable proportion of dark brown 'veins'. This makes Muiracatiara wood particularly decorative. After exposure to sunlight, the wood quickly turns to an orange-reddish brown to deep red brown. The sapwood is easily distinguishable as it has a straight wire with few irregularities. The grain is fine.

Grain

Straight to cross-thread, sometimes slightly wavy.

Timber texture

Fine to moderately coarse.

Stability

Low to medium.

Drying

Natural drying in the open air can be done without any problems. Accelerated drying of Tigerwood can lead to surface cracks.

Hardness

7700-9600 N.

Workability

The Muiracatiara FSC wood is easy to work with, despite the high density. Gluing is reasonable easy and we have good experiences with finishing. Pre-drilling is recommended. The wood dries fairly quickly, but this process must be done carefully to avoid surface cracks in thin wood and longitudinal cracks in thicker wood.

Screwing/nailing

Good. Pre-drilling is necessary.

Finishing of surface

Good with lacquer and varnish. After sanding, finishing and/or lacquering, it can show its beautiful pattern.

Astronium spec. div.
