Product Characteristics

High Melting Point: The melting point of Welding with Contact is typically between 700-1000℃, much higher than that of solder, allowing it to withstand high-temperature working environments.

 

Good Conductivity: Silver itself is an excellent conductor of electricity, resulting in Silver Alloys and Components with excellent conductivity, particularly prominent in high-frequency electronic equipment.

 

Good Thermal Conductivity: Composite Weld Contact possesses excellent thermal conductivity, making it widely used in applications requiring heat dissipation.

 

Good Soldering Performance: welding Silver contact exhibits excellent soldering performance and can be soldered to a variety of metal materials.

Comparison with Other Welding Materials

Compared to solder, Welded Silver Contacts have a higher melting point and better conductivity, making them suitable for high-temperature, high-frequency electronic devices. Compared to gold solder, silver brazing sheets offer superior conductivity, making them more suitable for high-precision electronic devices, while also being easier to process and use.
