Eucalyptus

Common Uses: Utility lumber, pallets, paper (pulpwood), fence posts, flooring, veneer, and turned objects.

Grain/Texture Grain is interlocked, with a uniform medium to coarse texture. Low natural luster.

Workability: Gives moderately good results with hand and machine tools, though boards with an interlocked grain (especially on quartersawn surfaces) frequently cause tear out during planing and other surfacing operations. Blue Gum tends to have many internal stresses and drying difficulties, and also has a large amount of movement in service, which excludes it from being used in applications where stability is important. Glues and finishes well.

Color/Appearance: Heartwood is a light yellowish brown. Narrow sapwood is a pale gray/white. Boards with mottled figure are sometimes seen, as well as solid burl sections and veneer.

Rot Resistance: Rated as moderately durable, though susceptible to insect attack.

Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.

Endgrain: Diffuse-porous; exclusively solitary; large to very large pores in radial/diagonal arrangement, very few; tyloses occasionally present; parenchyma vasicentric; narrow rays not visible without lens, spacing fairly close.
