Grain Pattern
Interlocked and wavy grain with a fine, uniform texture. Shows subtle figure and small checks characteristic of dense eucalyptus species.
Color & Appearance
Medium to deep reddish-brown heartwood. The color typically deepens with age and exposure to light, turning a rich dark red or burgundy.
Hardness (Janka)
Appx. 1,910 lbf (Jarrah) or 2,900 lbf (Red Gum); Very Hard to Extremely Hard.
Durability & Decay Resistance
Durable to Very Durable; excellent resistance to rot, termites, and fungal attack. Widely used for exterior applications.
Value & Sustainability
- Estimated Market Value
- $12.00 to $18.00 per board foot depending on figure and availability in the export market.
- Wood Age Estimate
- Recently milled or sanded (approx. 1-5 years post-processing) based on the freshness of the red hues and limited oxidation.
- Sustainability Status
- Generally stable; not listed on CITES appendices. IUCN Red List indicates Least Concern, often sourced from managed forests.
Common Uses
Outdoor furniture, flooring, heavy construction, decking, cabinetry, and woodturning.
Geographic Origin
Native to Australia (predominantly Western Australia and Murray-Darling basin).
Workability
Difficult to work due to high density and interlocked grain. Frequent tearout during planing; requires sharp carbide tooling. Glues and finishes well.
Finish Recommendations
Penetrating oils or film-building finishes like polyurethane. Requires thorough sanding to high grits to handle the dense grain.
Notable Features
Distinctively heavy and dense. High tannin content can cause blue-black staining if in contact with iron and water.
