Electrical Precision AgNi Silver Nickel Contacts For Relay And Contactor Use

Product Description

Silver nickel contacts (AgNi contacts) are widely used in electrical switching components due to their excellent electrical conductivity, arc erosion resistance, and stable mechanical properties. The combination of silver and nickel provides a good balance between conductivity and durability, making them suitable for medium and high switching loads.

Compared with pure silver contacts, silver nickel contacts offer improved resistance to arc erosion and reduced contact welding during switching operations. This ensures longer service life and reliable performance in demanding electrical environments.

Silver nickel contacts are commonly manufactured in forms such as contact rivets, contact tips, and contact buttons. They are widely applied in switches, relays, contactors, and circuit breakers used in household appliances, industrial equipment, and power control systems.

Custom alloy compositions, dimensions, and bonding methods can be provided according to specific application requirements.
