What is azobé?

Azobé is the trade name of Lophira alata from West and Central Africa, also sold as ekki and bongossi. It is one of the heaviest and most durable commercial timbers in the world.

Characteristics

The heartwood ranges from dark red to chocolate brown, with clearly lighter sapwood. It has a coarse texture and a markedly interlocked grain. At about 1,060 kg/m³ it sinks in water, and its crushing and bending strength are very high. It moves a lot while drying, so it needs slow, controlled drying, and it is hard enough to require pre-drilling for screws and nails.

Durability

It is durable against fungi, termites and dry-wood borers and gives long service in contact with water and ground.

Where is it used?

  • Jetties, quays and freshwater or marine works
  • Bridge decks and structures
  • Truck, wagon and container floors
  • Industrial and heavy-duty flooring
  • Sleepers, piles and heavy structures
