I just received a piece of Austrian Buloke in the mail. Said to be the world's hardest wood with a Janka hardness rating of 5060 lbf. My question is, how hard is this compared to metal? The Janka hardness test measures the force required to push a 11.28mm steel ball halfway into a sample of wood. I'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't find any data on someone trying the Janka test on different types of metal. Metal has different tests for harness, but I can't find any conversion method between that and the Janka test. Any thoughts?
P.S. It's not really a firewood question (unless you plan on burning Buloke), but I couldn't find a better spot for it.
