The materials of electronic contact pieces vary depending on their usage. Common materials include copper electrical contact pieces, silver contact pieces, and alloy contact pieces. Copper contact pieces have good conductivity and thermal stability, and are widely used in various electronic devices. Silver contact pieces have high conductivity, low coefficient of thermal expansion, and good wear resistance, making them suitable for use in situations that require high current and low voltage. Alloy electrical contact pieces are composite materials composed of two or more metal materials, with high conductivity, high thermal diffusivity, good corrosion resistance, and mechanical strength.
In addition, some special electronic contact pieces may require the use of special materials, such as tungsten alloys. Tungsten alloys have high hardness, wear resistance, and high-temperature stability, making them suitable for high voltage and high current applications.
In general, the material of electrical contact pieces needs to have excellent conductivity, wear resistance, corrosion resistance, and high-temperature stability to ensure their normal operation and stability. Meanwhile, different types of electronic contact material can be selected according to different application requirements and conditions.
Brass Copper Electrical Contacts have the following important characteristics:
Good conductivity: copper has excellent conductivity, while brass contains a certain proportion of copper, so it also has good conductivity, which can effectively transmit current and reduce power loss.
High strength and hardness: compared with pure copper, the strength and hardness of brass are improved, so that it can withstand certain mechanical pressure and wear, and is not easy to deform.
Corrosion resistance: with certain corrosion resistance, it can maintain stable performance in relatively severe environment and prolong the service life.
Good machining performance: easy to process various shapes and sizes of electrical contacts through forging, punching, cutting and other processes to meet different application requirements.
Relatively moderate cost: on the basis of guaranteeing certain performance, the price of brass is relatively reasonable and has a certain cost advantage.
Brass copper electrical contacts are widely used in the following scenarios:
In the power switchgear, such as circuit breaker and contactor, the circuit shall be reliably switched on and off.
In industrial control system, it is used for connection of sensor, relay and other components.
In household appliances, such as sockets, plugs, etc., provide stable power transmission.
In the power control room of a large plant, the brass copper-electric contacts play a key role in various switchgears, ensuring the stable power supply of production equipment; In ordinary household electrical sockets, they provide reliable connection for daily electricity consumption.
