Pure Copper Electrical Contacts
OVERVIEW
Pure Copper Electrical Contacts are key components in electrical connections, mainly used to connect, disconnect or conduct current in conductive circuits. Their performance directly affects the reliability and life of the equipment. As a professional supplier in the nonferrous metal field with more than 20 years of production and sales experience, FANMETAL can also provide customers with high-quality Tungsten Copper Contacts.
FEATURES
Excellent electrical and thermal conductivity
Under the same current, pure copper contacts have lower contact resistance and generate less heat, making them suitable for high current scenarios. They can also quickly dissipate the heat generated by the arc and reduce the risk of contact erosion.
Excellent anti-oxidation and anti-corrosion properties
A thin layer of conductive copper oxide is easily formed on the surface, which will not fail due to oxidation during long-term use. In addition, the high melting point and thermal conductivity of pure copper can quickly disperse arc energy and reduce contact erosion.
Strong wear resistance
Through surface treatment (such as gold plating or silver plating), its hardness can be increased from HV80 to above HV500, which can significantly extend the service life (such as in high-frequency elevator contactors).
Good processing performance
Pure copper is easy to stamp, weld, and electroplate (such as nickel plating and gold plating), and can be made into contacts of complex shapes to meet different structural requirements.
Pure Copper Electrical Contacts APPLICATION
| Electronic devices | Function | |
| Circuit on/off control | Relays, switches, contactors, and other low-voltage electrical appliances | The on-off control of the circuit is achieved by closing (conducting current) or opening (cutting off current) the contacts. |
| Current conduction and contact | Electrical interfaces such as sockets, terminal blocks, connectors, etc. | As a "bridge" for current transmission, it ensures stable current conduction between different components |
| Signal transmission and precision connection | Precision instruments, electronic components (such as micro switches, sensors) | In weak signal transmission scenarios, pure copper contacts use low impedance characteristics to ensure that the signal is not distorted or attenuated. |
- Power system: high-voltage vacuum circuit breakers, isolating switches for electrical equipment maintenance, and distribution boxes.
- Electronic communications: connection contacts between integrated circuit chips and circuit boards, small signal relays, and pressure sensors.
- Household appliances: microwave oven door switches or power switches, smart sockets, and headphone charger interfaces.
- Automotive manufacturing: automotive relays and contactors, on-board switches (such as ignition switches, wiper switches, and air conditioning control switch contacts).
- Lighting industry: power connectors and lamp holder contacts of LED lamps. Pure copper materials can reduce contact resistance and heat generation.
- Medical devices: Signal input contacts, such as electrocardiographs and monitors, require low noise and corrosion resistance to ensure accurate signal acquisition.

PROCESS
- High-purity copper materials are produced by vacuum melting, usually ≥99.9%, to ensure excellent conductivity and corrosion resistance.
- Depending on the size and structure of the contacts, different forming processes are selected, such as stamping, wire cutting, hot forging, casting, etc.
- Surface treatment is used to enhance oxidation resistance and reduce contact resistance, such as plating or mechanical polishing.
- Subsequent precision processing, such as turning, milling, laser welding, etc., ensures its dimensional accuracy and product quality.
