Tallowwood
Eucalyptus microcorys
Tallowwood is a large hardwood found along the coast and
coastal ranges between the
Rough bark persists to the
small branches and is brown to red-brown, soft and fibrous.
Appearance
The heartwood is a greyish-yellow colour with tinges
of olive green and is a hard, fairly close-grained timber. The sapwood is
distinctly paler. The timber is free of gum vein, something quite rare in
eucalypts.
The timber has a slightly
‘greasy’ feel which comes from the high levels of triterpenes
among its extracts. This feature can also impact on adhesive bond strength to
the material. The problem can be resolved to a certain extent by washing the
area(s) to be glued with a 10% solution of sodium hydroxide.
Properties
The heartwood is very
durable (Class 1). The material works well and has been widely used in a
variety of applications including decking, flooring, domestic structures, heavy
commercial construction, sleepers, marine structures, poles, piles and bridges.
