Functional features
Due to the good thermal conductivity of copper and its almost carbon-free nature, when tools and objects rub or hit, short The heat generated within a period of time is absorbed and conducted. Another reason is that copper itself is relatively soft and has good yielding properties during friction and impact. It is not easy to produce tiny metal particles, so we can hardly see sparks. Therefore, explosion-proof tools are also called explosion-proof tools. For non-sparking tools.
