With customized, cutting-edge design, they achieve precise arc extinguishing, efficient conductivity, and long-term durability under harsh conditions such as high frequency and high voltage, solving the pain points of traditional contacts, such as easy burning and short lifespan. We have deep expertise in this field, creating a full-specification product system adapted to diverse scenarios from micro-relay signal transmission to high-voltage switch disconnection. Our customized solutions meet the needs of "precise arc extinguishing, efficient conduction, and long-term stability," making us a trusted core component partner for professional customers worldwide.

 

Production Process

Material Preparation

The production process begins with the careful selection and preparation of high - quality tungsten and copper materials. Our suppliers provide raw materials that are inspected for quality and consistency. Once the materials pass our stringent inspection standards, they are cut to size and prepared for the manufacturing process.

Precision Machining

The prepared materials are then loaded into our precision machining equipment. These machines use advanced tooling systems to shape and form the tungsten and copper into the desired contact tip configuration. Our technicians closely monitor the process to ensure that the tolerances are maintained and the surface finish is smooth.

Sintering and Bonding

After the machining process, the tungsten and copper components undergo a sintering and bonding process. This process ensures that the tungsten and copper are perfectly bonded, providing a seamless and reliable electrical connection. Our advanced sintering equipment ensures precise temperature control and consistent results.

 

 

Final Inspection and Packaging

Once the sintering and bonding process is complete, the Tungsten-Copper Contact Pieces undergo a final inspection to ensure that they meet all quality standards. The inspection process includes visual checks, dimensional measurements, and functional testing where applicable. After passing the final inspection, the contact tips are carefully packaged to protect them during transit. Our packaging materials are designed to prevent damage and ensure that the contact tips arrive in perfect condition.

Manufacturing Technology and Application

 

Powder Metallurgy and Vacuum Sintering Process: The manufacturing process of copper-tungsten contacts utilizes advanced powder metallurgy technology. High-purity tungsten and copper powders are mixed in precise proportions and then sintered at high temperatures. This process ensures the uniformity and density of the material, giving the contacts excellent wear resistance, oxidation resistance, and high-temperature performance. Furthermore, vacuum sintering technology prevents the material from reacting with oxygen in the air during sintering, ensuring high fusion of tungsten and copper, thereby optimizing the contact's conductivity and arc resistance. This manufacturing process makes Tungsten-Copper Contact Sections ideal for high-current-density welding applications and electrical equipment.

 

Application Areas: In the welding industry, the high-temperature resistance and arc resistance of Tungsten-Copper Contact Elements make them an ideal choice for high-temperature operations such as arc welding and spot welding. They can withstand strong currents and high-temperature environments, ensuring stable current conduction and preventing equipment damage or quality problems caused by arcing. Furthermore, Tungsten-Copper Contact Materials are widely used in electrical equipment such as switches, circuit breakers, and contactors due to their efficient current conduction and rapid heat dissipation, ensuring stable operation over extended periods. They are particularly suitable for high-power, high-frequency electrical connections.

 

CNC Machining and Surface Treatment Technology: To ensure the precision and surface quality of the Tungsten-Copper Contact Pieces, we employ advanced CNC machining technology to precisely cut and mill the contacts, ensuring the size, shape, and smoothness of each contact surface. This precision machining process effectively reduces contact resistance, improving current transmission efficiency and lifespan. Simultaneously, to further enhance the corrosion resistance and wear resistance of the copper-tungsten contacts, we plate their surface with silver or gold, enhancing their reliability in harsh working environments.

 

Application Areas: CNC machining technology ensures that Tungsten-Copper Contact Tips can be precisely adapted to various high-end electrical equipment, widely used in high-frequency, high-power electrical systems, such as communication equipment, power tools, and automation equipment. Their high precision and durability make them particularly suitable for battery management systems and electrical connectors in new energy vehicles, smart grids, and other fields. Furthermore, the surface treatment process of copper-tungsten contacts enables them to maintain high efficiency for extended periods in high-load environments such as electric vehicles and industrial robots, meeting the growing market demand.
