Hand tools used in flammable and explosive places should be made of non-steel to avoid the combustion and explosion of surrounding combustible materials caused by sparks caused by collision and friction between steel and steel or steel and cement floor, rock, etc. This type of hand tool made of non-steel and used in flammable and explosive places is called explosion-proof tool . The material of explosion-proof tools is copper alloy. Due to the good thermal conductivity of copper and the characteristics of almost no carbon, the heat generated in a short time is absorbed and conducted when the tool and the object are rubbed or collided. Another reason is that the copper itself is relatively soft. It has good concessionality during friction and impact, and it is not easy to produce tiny metal particles, so we can hardly see sparks, therefore, explosion-proof tools are also known as non-sparking tools
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. They are very suitable for manufacturing safety tools used in explosive, flammable, strong magnetic and corrosive occasions. BeA-20C alloy withstands 561IJ of impact energy in 30% hydrogen or 6.5-10% methane air oxygen for 20 times without spark and combustion. Petroleum refining and petrochemical industry, coal mine, oil field, natural gas chemical industry, gunpowder industry, chemical fiber industry, paint industry, fertilizer industry, various pharmaceutical industries. Oil wheel and LPG vehicles, aircraft, warehouses dealing in flammable and explosive materials, electrolysis workshops, communication machine assembly workshops, places requiring tools not to rust, wear-resistant and anti-magnetic, etc.
