Brass is widely used in many fields due to its excellent physical and chemical properties. ‌Brass is an alloy composed of copper and zinc. It has high strength, good wear resistance and chemical corrosion resistance. Therefore, it is often used in the manufacture of valves, water pipes, air conditioner internal and external unit connecting pipes and radiators. Different grades of brass have different application fields due to their different characteristics. For example, CuZn30 brass is often used in heat exchangers, papermaking tubes, mechanical and electronic parts due to its good plasticity and high strength. H65 brass is often used in hardware products, lighting, pipe fittings, etc. due to its good mechanical properties and process properties. H70 brass is often used in radiator shells, conduits, bellows, etc. due to its good mechanical properties and hot plasticity. ‌

In addition, brass also has many variants, such as nickel brass, lead brass, manganese brass, etc. These variants are widely used in specific fields due to their specific chemical composition and physical properties. For example, nickel brass is often used to make metal coins, pressure gauge tubes, etc. Lead brass is widely used in connectors and valves in mechanical engineering due to its low cost and good cutting properties. Manganese brass is often used in ships and marine engineering because of its good strength and hot and cold processing properties.
