III. Product Details
1. Material characteristics: Mainly use brass alloys such as H62 and H65. H62 brass contains about 62% copper, has high strength and good cutting performance, and is suitable for manufacturing nuts, bolts and other connectors; H65 brass has better plasticity and is often used to manufacture parts that require cold deformation processing, such as springs, gaskets, etc. The addition of zinc to the alloy further enhances its hardness and corrosion resistance.
2. Manufacturing process: The production process covers melting, forging, machining, surface treatment and other links. The temperature and composition ratio are strictly controlled in the melting and casting stage to ensure the uniformity of the alloy; forging makes the internal structure of the material dense and improves the mechanical properties; CNC lathes, grinders and other equipment are used for fine processing to create complex shapes and high-precision dimensions; finally, through surface treatment processes such as electroplating and passivation, the beauty and protection performance of the parts are enhanced.
3. Application scenarios: In hydraulic systems, brass parts can be used as joints and valves, and their sealing performance and pressure resistance ensure stable fluid transmission; in automobile engines, brass bushings can effectively reduce friction, reduce wear, and increase engine service life; in power equipment, brass contacts have good conductivity and oxidation resistance to ensure stable and reliable power connections.
