  • Why does grinding steel create sparks but aluminium doesn t

    While grinding metal sparks are produced because of Friction. The rotating grinder cuts through the metal molecules rubbing against them and producing heat. Some particles get loose in this process and burn because of this heat. From Wikipedia "Steel is an alloy of iron with carbon being the primary alloying element up to 2.1 by weight
