Heartwood color is variable, ranging from a very pale pink to a deeper reddish brown, sometimes with streaks of medium to dark reddish brown. Color tends to darken with age. Quartersawn surfaces can also exhibit a ribbon-stripe appearance.


Grain is straight to interlocked, with a medium to coarse texture. Good natural luster with a light-reflecting optical phenomenon known as chatoyancy.


Diffuse-porous; large to very large pores, very few; solitary and radial multiples; orange/brown deposits occasionally present; growth rings usually indistinct, though sometimes distinct due to terminal parenchyma; rays medium to wide, fairly close spacing; parenchyma scanty to vasicentric, and occasionally marginal (not typical for Khaya spp.).

Rot Resistance:

Rated as moderately durable.


Easy to work, glue, and finish.


No characteristic odor.

Common Uses:

Veneer, plywood, turned items, furniture, boatbuilding, and interior trim. Among its more exotic uses is that in musical instruments. It is used for the back and sides of acoustic guitar bodies, as well as the tops of electric guitar bodies.


Sapele is in the same family as Mahogany and shares many of its qualities.
Sapele contains an interlocking grain that produces light and dark ribbon stripes throughout the boards. Sapele is often quartersawn to highlight these ribbons, and it is often used as a veneer for plywood in this application. It is stable once dry, and it is frequently used in the construction of doors.
