Iroko Chlorophora excelsa

DURABLE HARDWOOD FOR LONG-LASTING JOINERY
Iroko is the utility lumber of the tropical hardwood species. A durable wood, it is used largely for nondecorative purposes, and the oily texture indicates its usefulness for boat building and pilings. Even but coarse, the grain is clearly interlocking and is very difficult to work with hand tools. However, iroko takes a good edge and comes up to a beautiful luster.

VARIATIONS
What you see is what you get with iroko, and quartersawn and plain-sawn sides differ very little.

SUSTAINABILITY
Iroko has been designated as vulnerable on some lists of threatened species, though other, more authoritative reports say it is at a low risk only. It is not an easy lumber to find from a certified source, though that may improve.

AVAILABILITY AND COST

Not the most expensive tropical hardwood, and available from yards that stock exotics.
