Sales Contact Shi Dongmei Mobile Telephone Fax Email@ Explosion-proof tools are collectively referred to as safety tools and non-sparking tools internationally, and are collectively referred to as explosion-proof tools in China. Explosion-proof tools produced, sold, and circulated in China can be divided into two major categories based on materials: copper alloy (commonly known as aluminum bronze) explosion-proof tools. The specific material is high-purity electrolytic copper as a base with appropriate amounts of aluminum, nickel, manganese, iron and other metals. , forming a copper-based alloy. Copper alloy (commonly known as beryllium bronze) explosion-proof tools are made of high-purity electrolytic copper as a base and appropriate amounts of beryllium, nickel and other metals are added to form a copper-based alloy. Both materials have very good thermal and electrical conductivity. After heat treatment, the hardness and wear resistance of aluminum bronze are almost the same as those of beryllium bronze. However, the magnetism of aluminum bronze is slightly higher than that of beryllium bronze, but both belong to the micromagnetic range. Both aluminum bronze and beryllium bronze can be used in strong magnetic field environment. Explosion-proof tools can also be divided into two major categories based on their manufacturing process. The manufacturing process is a traditional manufacturing process. It is an internationally common technology for manufacturing explosion-proof tools in the 1990s and is still used by most domestic explosion-proof tool manufacturers today. The advantages of the casting process are simple process and low manufacturing cost. Disadvantages: The product has low density, hardness, tensile strength, and torque, and has many pores and trachoma, resulting in a shorter service life. Manufacturing process The latest international manufacturing process is made by using a large press or punch machine and a high heat-resistant forming mold for one-time forging. The advantages of the forging process can greatly increase the product density, hardness, tensile strength, and torque, basically eliminate pores and trachoma, and make the mechanical performance and service life of the product about twice longer than that of the traditional casting process. Disadvantages include large investment in product equipment and molds, resulting in higher costs.
