Wood description [more info]
Heartwood is blonde with a characteristic patterned grain resembling snakeskin.

Wood density [more info]
Green density is about 1145 kg/m3, air-dry density about 805 kg/m3, and basic density about 640 kg/m3.

Shrinkage [more info]
Tangential and radial shrinkage are about 7.4 and 3.3 per cent respectively.

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