Relationship and other names

The wood, which occurs mainly in Indonesia and Malaysia, has a close relationship to the African species of Afzelia, and is also of the same botanical species.

Like many tropical woods, Merbau has consistently different names in the regional areas, under which it is occasionally offered in trade:

  • Intsia
  • Ipil
  • Kwila, occasionally too
  • Hintzy
  • Mirabow or
  • Makamong

The DIN abbreviation is MEB.

Appearance

Grain

The appearance is also very similar to the structure of Afzelia. The structure is coarse, with scattered pores that are often filled with either yellowish or black deposits. The pores are often surrounded by eye-shaped fields. The wood rays are very fine at Merbau, and barely perceptible. The structure looks overall decorative.

colour

In terms of color, there may be differences in the individual woods throughout. The sapwood is always yellowish-white. The heartwood is initially brown to light reddish-brown and later darkens to a dark reddish brown. However, woods that come from Malaysia can also have a much lighter color after the darkening phase.

properties

The properties of merbau are essentially the same as those of the other Afzelia species. It is hard, heavy and has high strength properties that are superior to those of native woods such as oak. The editing is in most cases quite well, despite the high hardness. Special tools are required.

Shrinkage and drying

Drying should always be done as carefully as possible, but it will then run smoothly. Merbau dwindles significantly less than other Afzelia species, overall very little.

resistance

Merbau is weather-resistant and highly resistant to fungal and insect infestation (resistance class 1-2). In the rain, however, the wood separates yellowish-green to brownish substances.

use

Merbau, despite its decorative appearance, is mainly used as construction timber and in shipbuilding and bridge construction. However, use as parquet and for floor construction has become increasingly popular in recent years.

ancestry

Merbau comes mainly from Indonesia and Malaysia, but also occasionally from Madagascar and Papua New Guinea.

Prices)

Traders receive merbau at prices between around 1,900 and 2,300 EUR per m³.
