What industry are explosion-proof tools mainly used for

Explosion proof tools are mainly used in petroleum refining and Petrochemistry industry, coal mines, oil fields, natural gas chemical industry, gunpowder industry, chemical fiber industry, paint industry, fertilizer industry, and various pharmaceutical industries. Oil tankers and liquefied petroleum gas vehicles, aircraft, warehouses operating flammable and explosive materials, electrolysis workshops, communication machine assembly workshops, places where tools are required to be rust free, wear-resistant, and magnetic resistant.
The explosion-proof tools are made of beryllium bronze and aluminum bronze as raw materials. Beryllium bronze alloy and aluminum bronze alloy do not generate sparks during impact or friction, making them very suitable for manufacturing safety tools used in explosive, flammable, strong magnetic, and corrosive environments. The BeA-20C alloy withstands an impact energy of 561IJ in air oxygen containing 30% hydrogen or 6.5-10% methane, with 20 impacts without sparking or combustion.
The material of explosion-proof tools is copper alloy. Due to the good thermal conductivity and almost carbon free nature of copper, the heat generated during friction or impact between tools and objects is absorbed and transmitted in a short period of time. Another reason is that copper itself is relatively soft, and has good resilience during friction and impact, making it difficult to generate small metal particles and almost invisible sparks. Therefore, explosion-proof tools are also known as spark free tools.
