Yellow tingle

Eucalyptus guilfoylei

Yellow tingle is a medium to tall eucalypt, with height up to 35 m and diameter 1 m. It is generally smaller than red tingle (E. jacksonii) and Rate's tingle (E. brevistylis). Yellow tingle has a limited natural occurrence around the Deep and Frankland Rivers west of Albany, growing on slopes and ridges of undulating to hilly country. It occurs as scattered trees associated with other eucalypts, such as karri (E. diversicolor), marri (Corymbia calophylla) or the less common red tingle. The best growth of yellow tingle is on deep red loamy soils originating from basalts and dolerites. The species will grow on lighter loams from granites and schists.

Wood description [more info]
Heartwood is an oak-like yellow colour, hard and straight-grained.

Wood density [more info]
Green density is about 1185 kg/m3, air-dry density about 990 kg/m3.

Shrinkage [more info]
Tangential and radial shrinkage are estimated as... per cent respectively.

Workability [more info]
The timber relatively easy to work, dressing, sanding, drilling and carving are rated as good. Lacquer, wax or oils provides a good finish.

Durability [more info]
Durability Class based on the CSIRO 1996 ratings is 2 for decay and 3 for combined decay + termites.

Uses [more info]
Previous uses have been for sleepers, poles and bridge timbers. It has also been used for structural timber and flooring.

Availability [more info]
