Copper nuts are widely used in various fields such as electronics, automobiles, medical equipment, and plumbing systems due to their excellent electrical and thermal conductivity, corrosion resistance, and good bonding ability with plastic parts.
1. Electronic and Communication Equipment: Knurled copper nuts are often embedded in the plastic casings of electronic products such as mobile phones, laptops, and routers as internal threaded connectors. They are embedded into the plastic parts through hot-melt or ultrasonic processes, utilizing the knurling (such as mesh or diamond patterns) on the outer wall to form a mechanical engagement with the plastic, achieving high-strength fixation while avoiding the problem of easy wear of plastic threads.
2. Automotive Industry: Copper nuts are widely used in plastic components such as sensors, control modules, and interior trim parts in automobiles. For example, in automotive air conditioning systems, copper nuts are used to connect pipes and control valves, ensuring both sealing and resistance to high-temperature corrosion. Their good thermal conductivity also helps dissipate heat and improves system stability.
3. Medical Devices: Medical instrument casings and testing equipment have extremely high requirements for material cleanliness and connection reliability. Copper nuts are embedded via injection molding, ensuring the threads remain undamaged during repeated assembly and disassembly, while also meeting special requirements such as non-magnetic, conductive, and resistant to disinfectant corrosion.
4. Plumbing and Valve Systems Copper nuts are used in faucets, valves, and other components that are in constant contact with water to effectively prevent rust and electrochemical corrosion. The material itself (such as H59 brass) has antibacterial properties and meets drinking water safety standards.
