Common Name(s): Wenge

Scientific Name: Millettia laurentii

Distribution: Central Africa

Tree Size: 60-90 ft (18-27 m) tall, 3-4 ft (1-1.2 m) trunk diameter

Average Dried Weight: 54 lbs/ft3 (870 kg/m3)

Specific Gravity (Basic, 12% MC): .72, .87

Janka Hardness: 1,930 lbf (8,600 N)

Modulus of Rupture: 21,990 lbf/in2 (151.7 MPa)

Elastic Modulus: 2,550,000 lbf/in2 (17.59 GPa)

Crushing Strength: 11,710 lbf/in2 (80.7 MPa)

Shrinkage: Radial: 4.8%, Tangential: 8.1%, Volumetric: 12.9%, T/R Ratio: 1.7

Color/Appearance: Heartwood is medium brown, sometimes with a reddish or yellowish hue, with nearly black streaks. Upon application of a wood finish (particularly an oil finish) the wood can become nearly black.

Grain/Texture: Grain is straight, with a very coarse texture. Low natural luster.

Endgrain: Diffuse-porous; large to very large pores in no specific arrangement, very few; solitary and radial multiples of 2-3; dark brown mineral deposits occasionally present; medium rays not visible without lens, normal spacing; parenchyma vasicentric, confluent, with wide bands of parenchyma typically as thick as the pores.

Rot Resistance: Very durable, and resistant to termite attack.

Workability: Can be difficult to work with hand and machine tools. Blunts tool edges. Sands unevenly due to differences in density between light and dark areas. Very splintery—care must be used when handling unfinished wood with bare hands, as splinters have an increased risk of infection. Very large pores can be difficult to fill if a perfectly smooth/level finish is desired.

Odor: Wenge has a faint, slightly bitter scent when being worked.

Allergies/Toxicity: Although severe reactions are quite uncommon,  breathing Wenge wood dust has been reported to cause central nervous system effects, abdominal cramps, irritation of the skin and eyes, and is a sensitizer. Also, Wenge splinters tend to take longer to heal and  are more likely to go septic (get infected) than splinters from other woods. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Available in wide boards and veneer sheets. Prices are high, and are likely to remain so as supplies dwindle.

Sustainability: This wood species is not listed in the CITES Appendices, but is on the IUCN Red List. It is listed as endangered due to a population reduction of over 50% in the past three generations, caused by a decline in its natural range, and exploitation.

Common Uses: Veneer, paneling, furniture, turned objects, and musical instruments.

Comments: Usually pronounced WHEN-gii or WHEN-ghay, the wood has excellent strength and hardness properties, and is also dark enough to be used as a substitute for ebony.

    Found that cracks easy if not careful when giving pressure from point to point on lathe

    why would wenge have a blond center similar to sap wood

    • treetard

      The white color will disappear as the air gets to it. It’s common when the wood is cut from the log to see white color which fades with time.

    I am currently looking at an electric bass that has a neck of this material with a rosewood fretboard. Never seen anything like this and wondered how hardy it would be having strings putting stress on the wood?

    • ejmeier

      Wenge should be plenty strong for this.

  • matthew mclachlan

    I was looking at a few pieces of wenge & noticed how straight the grain is. Was wondering since I have been having trouble finding hickory in my area if making a hammer handle from wenge would be a good idea. Any thoughts? (Hammer would be for construction work so very hard on the hammer so any thoughts would be appreciated, if I should just save my money and search harder for some hickory :P

      It would be nice looking but watch out with the splinters !!!

    I use Wenge often in guitars I build often in the neck laminate or in the fret board. I find it to be easy enough to work with as long as you are aware that it will splinter on the edges and you can crack it if you try to bend it too much.
    This is a bass I built where the neck and body are carved out of a single piece of Bubinga. I then glued a Wenge fret board to the neck.

      can you get in contact with me on facebook about a wenge bass?

    Nothing better, in my opinion, than a wenge neck. Strong, beautiful, it sounds incredible and feels amazing! https://uploads.disquscdn.com/images/bde4fdd2b08f97ae87b95b3b06e4a3e45ab7582fef08997ad404dadd0058512e.jpg
