list of hardwoods by hardness and strength

Top Ten Hardest Woods | The Wood Database- list of hardwoods by hardness and strength ,by Eric Meier. The most common test for testing wood hardness is known as the Janka hardness test. The actual number listed in the wood profile is the amount of pounds-force (lb f) or newtons (N) required to imbed a .444″ (11.28 mm) diameter steel ball into the wood to half the ball’s diameter.Hardwoods of North America - fpl.fs.fed.usSources from which the strength data were obtained are referenced by numbers in parentheses and listed in the Additional Reading and References Cited sections. Data are given for strength tests on wood in the green and dry conditions. The properties include bending strength (modulus of rupture [MOR]), stiffness in bending (modulus of elas-
