Iroko is a hardwood commonly used for cabinetmaking and panelling. It’s quite durable, which makes it a perfect timber for most woodworking projects. Iroko is sometimes used as a cheaper alternative to teak because of similarities in features and colour and is also commonly called African teak. If you are a woodworker looking to know more about the characteristics, uses,price and properties of iroko wood, you’re at the right place.
Iroko Wood: Distribution and Basic Properties
Iroko wood can be further categorised into two species – Milicia excelsa (Chlorophora excelsa) and M. regia (C. regia). While Milicia excelsa can be found in most regions of tropical Africa, the distribution of M. regia is limited to the West African regions of Gambia and Ghana.
The hardwood of iroko is extracted from a tree that is about 100-130 ft in height and has a 3-5 ft (1-1.5 m) trunk diameter. The average dried weight of iroko wood is about 41 lbs/ft3 (660 kg/m3). It has a specific gravity of .55, .66 and the Janka hardness of 1,260 lbf (5,610 N). The iroko tree has long and widespread roots, which make it more stable against strong winds.
Other Basic Properties of Iroko Wood are as Follows:
Color & Appearance: Color of the outer layer, i.e. sapwood, of iroko is a pale yellow, which is very different from the color of the heartwood, i.e. the innermost part, which has a yellow to medium/dark brown color. The heartwood has light stripes all over it, which are quite visible on flat-sawn surfaces. The color of iroko hardwood is very similar to that of teak wood and tends to get dark over time.
Texture: The texture of Iroko hardwood is medium to coarse. It has interlocked grain, which may cause some tearouts when working with a machine. However, Iroko is typically easy to work with both hand and machine.
Resistance: Iroko has been categorised as very durable, and is similar to red maple in strength. It has very good resistance to insect attack, decay and rot and can be used for outdoor projects as well.
Since Iroko is a very durable wood, it doesn’t require much maintenance or perseverance, which reduces the cost of maintenance of the iroko wood items in the long term.
The Iroko tree also has environmental values, as it is said to have the ability to absorb CO2 from the air and transform it into limestone, which not only helps reduce the carbon but also enriches the soil, making it more fertile.
