Tallowwood

(Eucalyptus mmicrocorys.)

Description

This large hardwood grows between the Hunter River district of NSW and Maryborough in QLD. The heartwood is a pale yellow / brown and sometimes has a hint of olive green. The sapwood is paler. The grain is a little open and course, and unusually for a eucalypt it has no gum veins but will exhibit borer holes.

Workability

Tallowwood has numerous extractives making it difficult to glue.  Suggest a polyurethane adhesive for best results. 

Applications

Traditionally used for heavy engineering including wharfs, bridges and crossarms.  It also makes an excellent flooring and decking timber. .

Availability

Reasonably readily available as a floor board.  Sometimes we have decking and other kiln dried sizes for steps treads etc.

Hardness

Janka 8.6 990Kg/m3.  Very hard.

Durability

Heartwood very durable, sapwood lyctid susceptible
