How to Identify Xylia
Recognize Xylia (pyinkado) by its heavy heft, tan-to-reddish-brown heartwood, interlocked ribbon figure, and ironwood-hard feel — and tell it from keruing and merbau.

Start with weight and hardness, because Xylia earns its 'ironwood' name in the hand. A board feels distinctly heavy and dense for its size, and a thumbnail or awl barely marks it — this is a hard, tough wood, not a light utility timber. If a Southeast Asian hardwood feels notably heavy and resists denting, Xylia is a candidate.
Read the color and how it changes. Freshly cut or planed heartwood is light tan to pinkish-brown, and it darkens with exposure toward reddish- to dark-brown; a piece that shows a pale band alongside a warmer heart is showing sapwood against heartwood, which are reasonably well demarcated. The grain is fine to moderate in texture and frequently interlocked, so quartered faces carry a soft ribbon or stripe figure and a low to moderate sheen rather than any bold, flashy pattern.
Check the end grain. Xylia is diffuse-porous, with moderately sized pores; in the heartwood the pores are often partly occluded with pale or gummy deposits, and the growth zones can be marked by paler parenchyma lines characteristic of many legume woods. The wood works hard and dulls tools, and freshly cut stock has only a faint, nondescript odor — no strong aromatic or spicy scent to speak of.
The most likely confusions are with other dense reddish-brown Southeast Asian hardwoods. Merbau (Intsia) is a common look-alike but is typically a deeper orange- to dark-brown with conspicuous yellowish mineral flecks in its pores and a coarser texture. Keruing/gurjun (Dipterocarpus) is reddish-brown too but is usually more open-grained, often resinous or oily to the point of weeping, and less dense-feeling. Teak is lighter in weight, more golden-brown, and carries a distinct leathery scent and oily feel that Xylia lacks. When in doubt, the combination of ironwood weight, tan-to-red-brown color that darkens, and a subtle interlocked stripe points to Xylia.
Frequently asked questions
What is the fastest way to recognize Xylia?
Heft and hardness. It is heavy and dense, resists denting, and shows a tan to reddish-brown heartwood with a subtle interlocked ribbon figure. That ironwood weight combined with the warm, darkening color is the quickest tell.
How do I tell Xylia from merbau?
Both are dense reddish-brown Southeast Asian woods, but merbau is usually a deeper orange-brown with distinctive yellowish mineral deposits speckling its pores and a coarser texture. Xylia tends to be tan-to-red-brown with a finer, more even interlocked figure and no bright pore flecks.
Does Xylia have a distinctive smell?
Not really. Freshly cut Xylia has only a faint, neutral odor, which helps separate it from teak's leathery scent and from the resinous, oily smell of keruing. A near-scentless dense hardwood pointing tan-to-red is a good sign for Xylia.
Why do two Xylia samples look different in color?
Freshly cut heartwood is pale tan to pinkish-brown and darkens with age and light to reddish- or dark-brown, so the same wood can look quite different depending on exposure. Lighter pieces may also carry some of the paler, well-demarcated sapwood.
