Plain-Language Guide

Iroko is often called 'African teak' and earns the comparison — similar density, excellent outdoor durability, and good workability at a lower price than true teak. It's especially widely used in Europe, where it has a long history in the timber trade. The main issue is the dust: it is a documented sensitizer that causes real allergic reactions in many people, including skin rashes and respiratory irritation. Always work with respiratory protection. Interlocked grain can cause tearout if you plane against it.

Common Mistakes
  • Working without respiratory protection — the dust is a well-documented sensitizer and reactions can develop after years of safe exposure
  • Planing without checking grain direction first — interlocked grain tears badly if you go the wrong way
  • Assuming it's identical to teak; it's close in durability and appearance but lighter and less oily
Color & Appearance
Heartwood
Sapwood

Heartwood is golden yellow-brown, maturing to medium brown with age. May contain white calcareous (calcium) deposits that are harder than the surrounding wood and will chip cutting edges. Sapwood is pale yellow and clearly distinct.

Not typically used

Generally machines well. Interlocked grain requires attention to planing direction. Calcareous deposits (white mineral streaks) can unexpectedly blunt or chip cutting edges — inspect the board visually before planing. Glues well. Finishes adequately, though the coarse texture benefits from a grain filler for smooth results.

Notes
Known sensitizer — dust and skin contact cause skin rashes, eye irritation, and respiratory reactions. Sensitization can develop after prolonged exposure. Always wear a respirator and avoid skin contact. Dust is a documented sensitizer; reactions can be severe.

Sustainability: Not CITES listed, but overharvesting pressure exists in some West African regions. FSC-certified iroko is available and recommended. IUCN Near Threatened for Milicia excelsa. Verify sourcing.
