The Janka Test is a highly specialized hardness test that measures a particular type of wood’s ability to withstand denting and wear-and-tear. The pound-force it takes to drive in a steel ball halfway into a sample of wood calculates the Newton number. By this measure, Australian Buloke, an ironwood tree native to Australia, is the strongest available wood at 22,500 Newtons or 5060 pound-force.
This infographic ranks 75 wood-types according to Pound-force and Newtons. Note the graphics inside each wooden square – an indication of the best use of the specific wood.
