Introduction
AgNi (Silver-Nickel) Alloys are cadmium-free, eco-friendly contact materials made via powder metallurgy for a uniform microstructure. They offer high conductivity, stable contact resistance, and excellent wear resistance, serving as the green industry standard for low-voltage switching.

Frequently Asked Questions
Q: Can AgNi directly replace AgCdO in my existing relay design without modifying the contact geometry?
A: In the majority of resistive and mild inductive loads (under 10A), AgNi serves as a direct drop-in, eco-friendly replacement. However, for high-inrush inductive loads where severe arcing occurs, we recommend confirming with our engineering team to evaluate if a change to AgSnO₂ or a shift to a higher nickel content (like AgNi20) is required.
Q: How does the nickel content percentage (10% vs 20%) affect the performance of the alloy?
A: Increasing nickel content improves the material's mechanical hardness, arc-erosion resistance, and anti-welding properties. However, it also reduces overall electrical conductivity. AgNi10 is chosen for high conductivity and low contact resistance, while AgNi20 is preferred for higher mechanical switching frequencies and heavier loads.
Q: How do you prevent internal porosity in your AgNi alloys during the manufacturing process?
A: We use high-pressure powder compacting followed by closely monitored liquid-phase protective atmosphere sintering and subsequent high-ratio cold working. This process achieves an actual material density exceeding 99.5% of the theoretical density, effectively eliminating internal porosity.
Q: Are your materials completely free of conflict minerals?
A: Yes. We enforce a strict Responsible Minerals Sourcing policy. All silver and nickel raw materials are sourced exclusively from LBMA-certified refiners and conflict-free verified smelters, fully meeting Western corporate compliance mandates.
Q: Can you provide customized tape-and-reel packaging for automated pick-and-place manufacturing?
A: Yes. Our stamping and components division can supply finished AgNi contact tips or bimetal stampings on standard carrier tapes or specialized plastic trays engineered to interface directly with your automated high-speed production assembly lines.
