(Summary description)As an ordinary hand tool, box spanner is widely used in daily life, machinery manufacturing and machinery maintenance. The explosion-proof box wrenches used in gas stations and gas maintenance are fundamentally different from the ordinary box wrenches in terms of material. The ordinary box wrenches are made of 45 # steel or stainless steel, which is easy to produce sparks after being knocked in use and cannot play the explosion-proof function. The explosion-proof box wrench is made of high-quality beryllium bronze or aluminum bronze as raw materials. The explosion-proof box wrench is made of II C beryllium bronze, which does not detonate gas when operating in hydrogen with a concentration of 21%; Another aluminum bronze explosion-proof box spanner, which belongs to IIB product, does not detonate gas when operating in ethylene gas with a concentration of 7.8%. Beryllium bronze tools, also known as antimagnetic tools, can work safely in the magnetic field environment because of its zero magnetism. The explosion-proof products of these two materials can play the explosion-proof function after processing. And beryllium bronze alloy products are both explosion-proof and antimagnetic products, which are particularly suitable for use in places with stricter requirements. The performance of explosion-proof box wrench is also reflected in its good tensile strength. The tensile strength of aluminum bronze explosion-proof box wrench can reach more than 25 degrees, and the tensile strength of beryllium bronze explosion-proof box wrench can reach more than 35 degrees. These two explosion-proof box wrench products with different strengths are available for customers to choose different workplaces to use our explosion-proof tools
