Goldfields blackbutt is a small to medium-sized tree up to 12 m tall, often with a short trunk. The dark rough bark at the base changes to smooth white, often powdery bark.

Wood description [more info]
Heartwood is chocolate-brown, with an attractive grain.

Wood density [more info]
Green density is about 1180 kg/m3, air-dry density about 1130 kg/m3, and basic density about 880 kg/m3.

Shrinkage [more info]
Tangential and radial shrinkage are about 5.5 and 4.2 per cent respectively.

Workability [more info]
Goldfields craftsmen rate blackbutt as good for turning, machinability, boring, screwholding, stability and gluing, and excellent for sanding and finishing.

Durability [more info]
The wood is durable, and presumably CSIRO Durability Class 2.

Strength group and properties [more info]
Green and dry strength groups are (S2) and (SD2). The brackets indicate conservative provisional ratings based on the air-dry density. The more important strength properties based on the strength groups are given in the table below..

Uses [more info]
Uses during the gold rushes were for mining timber and fuelwood. The timber has potential for flooring and parquetry, general craftwork and specialty furniture.

Availability [more info]
Limited availability because of the scattered nature of the resource.
