Lightwood (Acacia implexa)
Lightwood (Acacia implexa)

Common Name(s): Lightwood, hickory wattle

Scientific Name: Acacia implexa

Distribution: Eastern Australia

Average Dried Weight: 49.9 lbs/ft3 (800 kg/m3)

Janka Hardness: 1,870 lbf (8,300 N)

Comments: With a density exceeding most temperate species found in North America, this Australian timber has a rather misleading common name—perhaps only rubberwood (Hevea brasiliensis) is a more confusing common name. Though it is not a true hickory in the Carya genus, the name hickory wattle is also applied to this species, and may be a more accurate description of this timber.

This website has some detailed info missing from your website on both acacia mangium and acacia auriculiformis. They also test a hybrid between the two, as well as a fast plantation grown version of a. mangium. They detail the quality of the methods they used for structural, physical, and rot resistance, and termite resistance properties.

G’day I’ve got some on my property and my neighbor has some also . Very rare now I’ve fenced off the remaining few I have and they’re reproducing .
