Products Description
Welding with Contacts are square, flat, sheet-shaped silver contact welding assemblies specifically designed for conductivity and on/off control in relays, circuit breakers, and new energy electrical systems. The product achieves a highly reliable metallurgical bond with the substrate through various welding processes, ensuring stable electrical performance while also maintaining mechanical strength and consistency in mass production.
Product Advantages
Versatile Welding Compatibility
Button Silver Contacts are compatible with four core welding processes: low-temperature welding, silver brazing, resistance welding, and high-frequency welding. Flexible selection based on operating conditions, production capacity, and performance requirements covers assembly needs across all scenarios.
01
High-Precision Dimensions
Brazed Electrical Contacts' dimensional accuracy is strictly controlled within ±0.02mm, with thicknesses ranging from 0.3-5mm. The flat, sheet-like structure facilitates precise welding, eliminating the need for secondary processing and significantly improving assembly efficiency and consistency.
02
Robust Welding
Welding Electrical Contact is adaptable to various welding process parameters, resulting in tight joints without porosity or peeling defects. Tensile strength ≥200MPa under silver brazing conditions eliminates the risk of detachment during operation.
03
Scenario-Specific Advantages
Designed specifically for high-current circuit breakers, it is also compatible with small relays and precision components in new energy applications, balancing high loads and precision conditions, offering both versatility and specificity.
04
Industry Application Cases
Low/Medium Voltage Circuit Breakers
Square silver welding sheet used for welding silver alloy contacts and arms, ensuring the joints maintain mechanical and electrical integrity even under short-circuit current surges, suitable for high-current circuit breakers.
New Energy High-Voltage Systems
Ensures long-term reliability of connection points under high voltage and high current conditions in the welding of core components such as main contactors and charging gun interfaces in new energy vehicles for Welding Electrical Contact.
Industrial Control and Power Equipment
Provides high-quality silver-based solder for welding various contactors, Brazed Electrical Contacts, and wires.
