Premium Australian Tonewood
Tasmanian Blackwood
Acacia melanoxylon
From warm golden brown to rich chocolate tones. Tasmanian Blackwood is an Australian hardwood admired for its beautiful natural figure, versatile working properties, and applications in guitar making, ukuleles, and fine woodworking.
01
What Is Tasmanian Blackwood?
Origin & Botanical Information
Tasmanian Blackwood (Acacia melanoxylon) is a hardwood native to eastern and southeastern Australia, including Tasmania. It belongs to the legume family (Fabaceae) and the genus Acacia.
The timber has long been valued for furniture, cabinetry, joinery, and decorative woodworking. Its attractive colors and grain patterns have also made it a popular choice among luthiers.
Tasmanian Blackwood is related to Hawaiian Koa through the genus Acacia. Both can display striking curly figure and warm brown coloration, making Blackwood an appealing option for musical instruments.

Wood Characteristics
Color, Figure & Workability
Grain & Figure
The grain is generally straight, but wavy or interlocked grain can produce attractive curly and fiddleback figure.
Density & Hardness
A moderately dense hardwood, Tasmanian Blackwood is used in furniture and musical instruments. Density and stiffness vary between individual boards.
Workability
Generally easy to saw, shape, sand, and finish. Highly figured areas may require extra care to prevent tear-out during machining.
03
Tasmanian Blackwood vs. Hawaiian Koa
Related Acacia Tonewoods
Tasmanian Blackwood and Hawaiian Koa both belong to the genus Acacia. They share certain visual characteristics, including warm golden-to-brown coloration and the potential for beautiful curly figure.
Tasmanian Blackwood
Acacia melanoxylon is native to Australia and is used for guitars, furniture, cabinetry, and decorative veneers.
Hawaiian Koa
Acacia koa is native to the Hawaiian Islands and is especially well known for ukuleles, guitars, furniture, and decorative woodworking.
Although both belong to the same genus,
they are distinct species.
Their appearance, density, stiffness,
and acoustic behavior can vary.
Similar visual characteristics
do not guarantee identical performance.

Musical Instrument Applications
Acoustic Properties & Tonewood
Tasmanian Blackwood is used for the backs and sides of acoustic guitars and ukuleles. Depending on the properties of the individual piece and the instrument design, it may also be used for soundboards and decorative electric guitar tops.
Luthiers sometimes describe Blackwood instruments as having a warm tonal character with clear, articulate response. Such descriptions are general impressions rather than fixed properties of the species.
The final sound of an instrument depends on wood density and stiffness, component thickness, bracing, body construction, and craftsmanship. No timber species alone guarantees a particular tone, sustain, or response.
05
Curly & Fiddleback Figure
Natural Beauty & Material Selection
Some Tasmanian Blackwood displays striking curly or fiddleback figure, created by variations in grain direction. These patterns can appear to move as the viewing angle changes, particularly under a carefully applied finish.
Pieces with attractive, consistent figure and suitable dimensions are especially desirable for decorative instrument parts and fine furniture.
When selecting material, consider not only its figure but also its dimensions, grain orientation, cracks, knots, moisture condition, and intended application.
Curly figure varies from piece
to piece. The intensity of
the figure alone does not
determine structural quality
or acoustic performance.
06
Recommended Applications
Instrument Making & Fine Woodworking
Acoustic Guitars
Back and side sets, selected soundboards, and decorative instrument components, depending on material properties and design.
Ukuleles
Tops, backs, and sides that showcase Blackwood's natural color and figure.
Electric Guitars & Basses
Decorative tops, suitable solid-body components, and other custom instrument parts.
Furniture & Woodworking
Fine furniture, cabinetry, decorative veneers, boxes, turned objects, and specialty craftwork.
07
Working, Drying & Storage
Workshop Considerations
Tasmanian Blackwood is generally regarded as a workable hardwood. However, wavy or interlocked grain may cause tear-out or chipping during planing and shaping.
Sharp cutting tools, controlled feed rates, and light cutting passes are recommended when working with highly figured material.
For instrument making, check the moisture condition and dimensional stability of the wood before machining. Allow the material to acclimate to the workshop environment.
Store timber away from direct sunlight and rapid fluctuations in temperature or humidity to reduce the risk of warping and checking.
Use appropriate dust extraction,
ventilation, and protective
equipment when machining
or sanding. Wood dust may
cause irritation or sensitivity
in some individuals.
