Square Silver Contact
Products Description
Manufactured from highly conductive and arc erosion-resistant silver-based alloys, the Square Silver Contact is a weldable component widely found in relays, contactors, circuit breakers, microswitches, temperature controllers, and new energy power electronics. Through welding, it is permanently affixed to substrates of copper, brass, stainless steel, or bimetallic composition, delivering stable current-carrying capability and enduring mechanical anchoring.
Main Features and Functions
Conductivity
The high-purity silver alloy layer provides stable, low contact resistance, suppressing temperature rise during high-current switching and preventing excessive voltage drop in the circuit.
Arc Resistance
The silver alloy incorporates arc-resistant metal components, suppressing arc propagation when breaking inductive loads and reducing surface ablation and burr formation on the Resistance Welding Silver Contact.
Mechanical Durability
The underlying support material possesses high strength and hardness, remaining undeformed under millions of mechanical opening and closing impacts, maintaining the Silver Brazing Sheet's contact surface.
Process Compatibility
The Low Voltage Electrical Contacts' end faces are compatible with various fixing methods such as projection welding, butt welding, and brazing, allowing for direct assembly without additional grinding or processing.
Material Advantages
Through our internally developed composite metal formulations, the silver alloy composition of the welding contacts can be tailored to the customer's operational profile, with specific improvements directed toward arc resistance or wear resistance as required.
All incoming raw materials are fully procured and controlled in-house, guaranteeing end-to-end traceability for both silver and base metals. Each production batch is accompanied by a material analysis report, effectively eliminating performance inconsistencies that may arise from impurities introduced by recycled or third-party sourced materials.
China Brazed Contact Assemblies' composite layer metallurgical bonding process replaces adhesives and electroplating, completely solving the engineering pain point of delamination failure under high-temperature conditions.
Flat Face Brazed Composite Rivet Contacts are free of harmful heavy metals, fully complying with RoHS and REACH environmental control standards, making them suitable for export to overseas new energy equipment.
Frequently Asked Questions
Do Flat Face Brazed Composite Rivet Contacts support customized dimensions and silver layer thickness?
Yes, length, width, total thickness, and silver layer percentage can all be customized according to customer circuit current and welding equipment parameters. Free samples are available for production line testing and verification.
Can the AgCuZn Solder Sheet sample represent the batch quality?
Yes. All samples are from the mass production line, using the same materials, molds, and process parameters, ensuring that sample evaluation results can be directly applied to bulk purchasing decisions.
Is the BAg-Series Silver Brazing Alloy product prone to oxidation and blackening during storage?
Finished products undergo passivation and anti-oxidation treatment at the factory. Under normal storage conditions with sealed packaging, no significant oxidation will occur within 6 months, and it will not affect the contact resistance performance.
