Blackbutt

Posted by:

Native to Australia, Eucalyptus Pilularis or coastal Blackbutt as it is popularly known, is a pale brown coloured wood with pink highlights. The grain of Blackbutt is mostly straight and although the sapwood is paler than the heartwood, it has a medium and even texture throughout the surface which makes it suitable for use in building various types of wooden structures.

The coastal Blackbutt found in Australia is not related to the tableland species of Blackbutt (Eucalyptus Andrewsii Ssp Campanulata) that grows in New England, Australia. This tree got its name due to the reason that it is the least flammable of the Eucalyptus species and it usually survives moderate forest fires with just a slight blackening of its bark while other species of trees in the same area probably get wiped out due to the intense heat and smoke.

This beautiful and strong hard wood is found along the coast of New South Wales from the town of Bega, New South Wales to the Maryborough in Queensland. http://en.wikipedia.org/wiki/

Timber Attributes:

  • Janka rating – Dry: Hard (7.1 – 10.0)
  • May surface check on the tangential when dried
  • May widen any existing surface checks when reconditioned
  • Poor base for most varieties of paints
  • Rates “fair” in the operation of steam bending
  • Can be stained easily using many popular finishes
  • Phenol based adhesive may be used on young regrowth
  • Structural Plywood may also be made using young regrowth

Major advantages of Blackbutt are lack of sapwood susceptibility to Lyctid borer attack as well as resistance of heartwood to termites and marine borer infestation. The stunning good looks and rugged durability of Blackbutt wood will last a long time regardless of the purpose it is used for.

Natural Durability Rating of any lumber species indicates the timber’s resistance to attack by insects and fungi that can destroy the entire wood, a little at a time. Above ground, the Heartwood is rated as Class 1 and in-ground, it is rated Class 2.

Blackbutt applications include:

  • Decking
  • Flooring
  • Building framework
  • Furniture
  • Sleepers
  • Cladding
  • Joinery
