Technical Features
Low-Temperature Brazing Process
Utilizes a patented brazing filler metal formula (melting point 680-750℃), reducing the temperature by 150℃ compared to traditional silver brazing, minimizing the heat-affected zone, and preventing bolt material performance degradation for Resistance Brazing Electrical Contacts.
Microstructure Optimization
By controlling the brazing cooling rate (5-10℃/s), a fine-grained structure is formed, increasing the contact-bolt interface bonding strength by 40% for Low Voltage Electrical Contacts.
Intelligent Design Tools
Provides 3D modeling and finite element analysis (FEA) services to simulate stress distribution under different operating conditions and optimize contact shape and bolt connection structure for Spot Welding Assembly.
Typical Application Scenarios
New Energy Sector
Power module connections in photovoltaic inverters, wind power converters, and energy storage systems for Brazing Silver Contacts to Copper Bars.
Industrial Automation
High-frequency switching control units for robot joints, servo drives, and CNC machine tools for Spot Welding Assembly.
Rail Transit
Key electrical nodes in traction converters, pantographs, and signaling systems for Low Voltage Electrical Contacts.
High-End Manufacturing
Precision power connections for semiconductor equipment, medical imaging equipment, and laser processing machines.
Main Functions
High-Efficiency Conductivity
The high conductivity of the silver contacts and the low-resistance brazed joint design ensure rapid and stable current transmission, reducing energy loss and preventing overheating due to excessive contact resistance. This guarantees normal operation of the equipment under high-current, high-frequency switching conditions for Resistance Brazing Electrical Contacts.
01
Robust Connection
The brazed joint, formed through metallurgical bonding, possesses excellent tensile and shear strength, withstanding vibrations, impacts, and other external forces during equipment operation. This ensures that the silver contacts and bolts will not detach or loosen, guaranteeing reliable connection for Low Voltage Electrical Contacts.
02
Wear Resistance
The selected silver material or silver alloy has excellent wear resistance and arc resistance, effectively resisting arc erosion and mechanical wear generated during current switching, extending product lifespan and reducing equipment maintenance frequency for Spot Welding Assembly.
03
Environmental Adaptability
The use of stainless steel bolts and anti-corrosion coatings, selected according to customer needs, gives the product excellent resistance to moisture, acids, alkalis, and high temperatures. It can operate stably in various harsh environments, broadening the product's application scenarios.
