Acacia and teak are two exotic hardwood varieties. They're both imported to the United States as furniture, fixtures and flooring, among other items. Most lumber yards that deal in exotic hardwoods commonly stock teak and acacia lumber in random widths, lengths and thicknesses. Acacia and teak are both are used almost interchangeably, with some differences in cost, aesthetics and durability.


Acacia Origination

Even though there are over 1,000 species worldwide, the bulk of the acacia used domestically comes from two varieties: Australian Blackwood and Hawaiian Koa.

Teak Origination

Some dealers refer to teak generically, but only one variety, Burmese teak, is widely grown and distributed, originating from plantations in Central and South America.


The Trees

Acacia is shrub-like tree; it takes years to reach maturity, and is generally regarded as an invasive species in many locations. Old-growth teak is somewhat elusive and hard to find. It yields wider boards than acacia. Contemporary teak is harvested at an early age. Neither teak or acacia are considered endangered.


Density and Hardness

The differences in hardness between acacia and teak are insignificant. Acacia from Blackwood has a density rating of 1,160 and from Hawaian Koa it ranks at 1,170 on the Janka hardness scale. Teak ranks just below acacia woods at 1,070. For the sake of comparison, domestic red oak is harder than both of them, ranking at 1,290.

Flooring Options

Teak and acacia have similar durability quality when applied as flooring. The major difference is in cost and aesthetics; acacia costs less than half the price of teak.


Acacia Advantages
