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.
As a manufacturer of brass and copper electrical contacts, we always adhere to the concept of “copper as the foundation, craftsmanship in casting points” and deeply cultivate the field of electrical connections. Brass and copper are ideal materials for electrical contacts due to their excellent conductivity, good processability, and stable physical properties. We use professional technology and strict standards to maximize these natural advantages and create high-performance electrical contact products for global customers.
We have established a strict screening system for the selection of raw materials. Selecting high-purity brass and copper materials to control product quality from the source. For brass, we strictly control the ratio of copper, zinc and other elements to ensure that it has good strength and conductivity; For pure copper, we use high-quality raw materials such as oxygen free copper to minimize impurity content and improve conductivity. Each batch of raw materials needs to be tested by professional equipment such as spectral analyzers. Only materials that fully meet the standards can enter the production process.
In the production and manufacturing process, we deeply integrate traditional craftsmanship with modern technology. On the one hand, inheriting classic processes such as precision stamping and forging ensures precise formation of the basic structure of the contacts; On the other hand, advanced CNC machining equipment and automated production lines are introduced to achieve high precision and efficiency in the production process. To optimize product performance, we have diversified surface treatments for brass and copper electrical contacts. By using processes such as nickel plating, tin plating, and gold plating, not only can the oxidation and corrosion resistance of the contacts be enhanced, but the contact resistance can also be further reduced, thereby improving electrical performance. At the same time, we utilize our independently developed mold technology to design customized molds for different specifications and uses of contacts, ensuring product dimensional accuracy reaches the micrometer level.
Quality control is the top priority of our production system. We have established a full process quality inspection mechanism, from raw material incoming inspection, production process sampling, to comprehensive testing of finished products, with strict standards implemented in every link. Equipped with professional equipment such as contact resistance tester, metallographic microscope, salt spray test chamber, etc., to comprehensively test the electrical performance, mechanical performance, and environmental adaptability of contacts. We simulate various extreme working conditions such as high temperature, high humidity, and strong vibration to conduct reliability tests on our products, ensuring that every brass and copper electrical contact can operate stably in complex environments.
With excellent product performance, our brass and copper electrical contacts have been widely used in various fields such as household appliances, automotive electronics, communication equipment, industrial automation, etc. In household appliances, our contacts ensure stable connection of the circuit; In the automotive engine control system, its reliable performance ensures precise signal transmission. In the future, we will continue to increase research and development investment, explore new materials and processes, continuously optimize the performance of brass and copper electrical contacts, meet the growing demand of the market with higher quality products and services, and contribute to the development of electrical connection technology.
