Al-Cu explosion-proof, the working surface hardness will be more than 25 degrees, in the flammable gas ethylene (concentration 7.8%) space of continuous use are to ensure safety, impact, friction, sparks an explosion not drop hammer

Explosion-proof tool for this skin copper alloy materials and precious metals for military synthesis, made of tool surface is also yellow. Face hardness of 365 degrees or higher. In the flammable gas hydrogen (concentration 21%) spatial continuity of quick access to both ensure safety, impact, friction, sparks an explosion not drop hammer. Skin copper alloy explosion-proof tool also has a special anti-magnetic features, in a magnetic field in the working environment can be used normally
