Janka wood hardness vs metal hardness Arboristsite.com The Janka hardness test measures the force required to push a 11.28mm steel ball halfway into a sample of wood. I& 39;m trying to understand how this relates to metal. It certainly has to be harder than lead or tin, but what about copper or aluminum? The problem is that I can& 39;t find any data on someone trying the Janka test on different types of metal.

Janka Hardness chart for Exotic Wood and Domestic Wood Bell ... The Janka scale is used to determine the relative hardness of particular domestic or exotic wood species. The Janka test measures the amount of force required to embed a 0.444" steel ball into the wood to half of its diameter. Woods with a higher rating are harder than woods with a lower rating. The scale used in the table is pounds-force.

wood hardness scale conversion - Discussion Forums - Banjo ... Janka was made to measure wear as well as hardness, but I never quite understood how this could work, as it is only a dent test. Mohs is a hardness scale that assesses this in one way, but still not what you want, as it is a scale of the scratch hardness of materials as compared to each other.

Material hardness and hardness testing – IspatGuru Baecol hardness, brinell hardness, hardnees, indenter, Mohs hardness, Rockwell hardness, shore hardness, strength, vickers hardness, Material hardness and hardness testing Material hardness is the property of the material which enables it to resist plastic deformation, usually by penetration or by indentation.
