Silver contacts

Product Description:

Silver nickel is more resistant to fusion welding and burnout than pure silver or fine-grained silver. Both of these properties of the product are improved due to the increased nickel content of the high melting point. All silver-nickel materials have good workability and are easy to weld. Less material transfer when switching on and off DC, silver and nickel are environmentally friendly materials

Overview: Silver nickel is more resistant to fusion welding and burnout than pure silver or fine-grained silver. Both of these properties of the product are improved due to the increased nickel content of the high melting point. All silver-nickel materials have good workability and are easy to weld. There is less material transfer when switching on and off DC, and silver and nickel are environmentally friendly materials.

Application range: Silver-nickel products are widely used in low-voltage switchgear. Such as relays, small current contactors, light switches, thermostats, protection switches (formed asymmetrically paired contacts with AgC, AgZnO, AgSnO2, etc.).
