DENSITY

The timber is moderately soft and light with a density of 440-660 kg/m3 air dry and an average density of 545 kg/m3 air dry.


NATURAL DURABILITY

The timber is moderately durable.


PRESERVATIVE TREATMENT

The amenability to preservative treatment is classified as average.


TEXTURE

Texture is fine and even with straight grain.


STRENGTH PROPERTIES

The timber falls into Strength Group C (Burgess, 1958) or SG4 (MS 544:Part 2:2001).


MACHINING PROPERTIES

It is easy to saw and work and the surface produced is smooth.


AIR DRYING

The timber seasons moderately slowly, with minor dimensional movements, end-checking, splitting and insect and fungal attacks as the main defects. 13 mm thick boards take 2 months to air dry, while 38 mm thick boards take 5 months.


SHRINKAGE

Shrinkage is average with radial shrinkage averaging 1.2% while tangential shrinkage averaging 2.5%.
