防爆工具材质为铜合金材质，详细分为铝青铜合金和铍青铜合金铜合金也会产生火花，铜合金虽然为防爆材质，但是也会产生火花，只是铜合金的导热性能好，所以在摩擦和撞击时不会产生火花。但是，当你拿铜合金材质和高速转向的切割机切割时，就会产生火花。 原因在于在这种情况下会产生大量的金属颗粒，同事短时间聚集的热量不能被全部吸收和传导，而我们拿锉刀或小锯条摩擦铜合金材质时，就不会产生火花现象，因为这时产生的热量能被及时的吸收和传导。
 Explosion-proof tools made of copper alloy material, details of aluminum bronze alloys and beryllium bronze alloy Copper alloy also produce sparks, copper alloy, although proof material, but also produce sparks, but copper alloy Good thermal conductivity, so the friction and impact will not produce sparks. However, when you take copper alloy and high-speed steering of the cutting machine cut, they will generate sparks. The reason is that in such circumstances would produce large amounts of metal particles, colleagues gathered short period of time can not be all of the heat absorption and conduction, and we take FILE or a small saw blade friction and copper alloy materials, they will not produce sparks phenomenon, because when heat absorption and conduction can be timely.
