High electrical performance silver nickel contact

High electrical performance silver nickel contact Silver contact refers to the electronic appliances when opening and closing, separation and mutual contact of intersections, because the metal conductor terminals at the instant of the contact prone to moments of fever and spark, prompting them to contact point in the process of using multiple frequency, prone to oxidation and electrolysis, so will increasing the thickness of the contact point, or manufactured polymer metal (copper and multiple) with different material, so will called silver contact.   Materials  Face Materials: AgNi10, AgNi12, AgNi15,AgNi30  Base Materials: C1100    Product Types: Solid Rivets, Hollow Rivets, Round head rivets, Flat head rivets, Bimetal rivets, Trimetal rivets and special type contact rivets are also available.   Bimetal type:     Trimetal type:     Characteristics 1. Silver nickel alloy Materials with high conductivity, low and stable contact resistance, the characteristics of small and medium-sized electrical flow has good welding performance and electric resistance wear resistance, less material transfer under DC condition. 2. Increase the Nickel content can improve the function of material fusion welding resistance, but will increase the contact resistance and the temperature rise
