Welding With Contacts
Products Description
Welding with Contacts is a key technology that firmly bonds "contact functional materials" to "metal carrier structural components," typically used in components such as switches, relays, circuit breakers, contactors, sockets, and electrical control systems that require frequent switching of electric arcs.
By welding, the contacts are stably solidified onto the metal substrate, ensuring:
Stable conductivity, reducing power loss
Improved arc resistance, reducing contact wear and ablation
Enhanced mechanical strength, ensuring long-term reliability
Maintaining a stable welding contact surface shape, ensuring sensitive operation
It is not a single product, but rather a combination of component manufacturing processes and structural components customized according to different contact materials, geometric designs, and application scenarios.
Material Advantages: The Engineering Wisdom of Contact Microstructure
Precise Selection of Contact Materials
We use nanoscale silver-nickel alloy as the core material for our contacts, instead of ordinary copper or Brazed Electrical Contacts. The advantages of this material in the field of electrical connections are:
Microscopic Mechanism of Oxidation Inhibition: The silver-nickel alloy forms a dense silver oxide protective layer in the air, preventing oxygen diffusion and controlling contact resistance fluctuations within ±2%, far superior to ordinary tin-plated contacts (fluctuations up to ±15%).
Engineering Value of Electromigration Protection: Under high-frequency current environments, the silver-nickel alloy inhibits electromigration, avoiding Welding Electrical Contact failures caused by contact material migration and ensuring long-term connection stability.
Precise Matching of Thermal Expansion Coefficient: The material's thermal expansion coefficient (16.5 × 10⁻⁶/℃) is highly matched to that of mainstream substrates, eliminating microcracks caused by thermal stress and achieving structural integrity during thermal cycling.
Engineering Application of Nanocoating: The Electrical Contact Resistance Brazing surface uses environmentally friendly nanocoating technology to form a 0.5μm thick protective layer. This coating is not a simple cover, but rather forms a metallurgical bond with the substrate through atomic diffusion, ensuring low contact resistance during long-term use while avoiding performance fluctuations caused by uneven thickness in traditional coatings.
