Janka Hardness: 5,060 lbf (22,510 N)
Modulus of Rupture: No data available
Elastic Modulus: No data available
Crushing Strength: No data available

Color/Appearance: Heartwood is reddish brown. Somewhat well defined sapwood is a light yellowish brown. Very large aggregate rays produce a lace-like pattern on quartersawn surfaces. Rays are so large, some pieces have visible ray flecking on flatsawn surfaces.
Grain/Texture: Grain is straight to slightly interlocked. Uniform medium texture with good natural luster.
Endgrain: Diffuse-porous; exclusively solitary; large pores in no specific arrangement, few; parenchyma diffuse-in-aggregates, banded; narrow rays not visible without lens, spacing close, aggregate rays are frequently very wide
Rot Resistance: No data available.
Workability: Can be difficult to work on account of its hardness. Tearout can occur during planing or surfacing, especially on quartersawn surfaces in the rays. Turns and finishes well.
Odor: No characteristic odor.
Allergies/Toxicity: Besides the standard health risks associated with any type of wood dust, no further health reactions have been associated with Buloke. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
Pricing/Availability: Seldom available outside Australia. Occasionally available as small turning blocks or craft blanks. Prices are high for an imported hardwood.
Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species. However, while the tree species itself may not be directly threatened by extinction, certain stands in Victoria and New South Wales are listed as endangered by the government of Australia.
Common Uses: Knife handles, flooring, fine furniture, and turned objects.
Comments: No data available.
