Overview
Tasmanian Blue Gum (Eucalyptus globulus) is a fast-growing Australian hardwood widely planted for timber and pulp. The wood offers good strength and a pale, even color suitable for flooring and furniture. Interlocked grain can challenge machining, but it finishes well and is valued for construction and decorative applications.
Heartwood pale yellowish brown to light tan; sapwood similar. Average dried density approximately 680 kg/m³ with Janka hardness of 1,320 lbf. Medium to coarse texture with interlocked or wavy grain. Growth rings often distinct.
