What is non spark tools?
The material of explosion-pring tools?oof tools is copper alloy. Because of its good thermal conductivity and almost no carbon content, the heat generated in a short time is absorbed and transmitted when the tools and objects are rubbed or impacted. Another reason is that the copper itself is relatively soft and has good yielding property when rubbing and impacting, so it is not easy to produce tiny metal particles. So we can hardly see sparks, so explosion-proof tools are also called sparkless tools.
