Color/Appearance: Has an orangish-brown color when freshly cut, which ages to a darker reddish-brown. Color between boards can be highly variable. There are also small yellow mineral deposits found throughout the wood, making it easier to separate from other lookalikes. (These yellow deposits are water-soluble and can cause staining.)
Grain/Texture: Grain is straight to interlocked. Texture is coarse, with a moderate natural luster.
Endgrain: Diffuse-porous; large to very large pores, very few; solitary and radial multiples; mineral deposits occasionally present, including conspicuous yellow deposits; narrow rays, normal spacing; parenchyma banded (marginal), paratracheal parenchyma vasicentric, aliform (winged or lozenge), and confluent.
Rot Resistance: Merbau is reported to be very durable, and resists both rotting and insect attack.
Workability: Glues and finishes well, though it can be difficult to saw due to gumming and dulling of teeth.
Odor: Has a unique smell when being sawed or sanded: which can also cause irritation and sneezing.
Allergies/Toxicity: Merbau has been associated with mild allergic reactions: most common is skin irritation and a runny nose. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
Pricing/Availability: Offered sporadically, lumber is usually sold in ample widths and lengths when available. Prices should be moderate for an imported hardwood.
Sustainability: This wood species is not listed in the CITES Appendices, but is on the IUCN Red List. It is listed as vulnerable due to a population reduction of over 20% in the past three generations, caused by a decline in its natural range, and exploitation.
Common Uses: Flooring, furniture, musical instruments, turned objects, and other specialty wood items.
Comments: This wood has excellent strength characteristics, along with excellent stability, making it ideally suited for use as wood flooring and other applications where strength is important.
None available.

I lived in PNG when I was in high school and I used to make clocks and desk organizers from this wood. It is beautiful with a Satin Polyurethane finish. Wish I could get some of this today.
