There are two kinds of material of non-sparking tools:
Beryllium copper alloy(non-sparking and anti-magnetism) , 35-40 hrc
And aluminium bronze alloy (non-sparking) , 25-30 hrc
These tools can efficiently avoid rising spark when tools strike, rub or collide with target in explosive atmosphere or flammable vapours.
Therefore, non-sparking tools are widely used in oil and gas works, petro-chemical plants, explosive manufactories, mines, shipyards, pipeline construction and many others.
