The Foundation of Silver Contact Manufacturing

At CD Silver (cdsilver.com), we categorize silver electrical contacts not just by their material composition, but by their mechanical geometry and composite structure. Whether you are using Solid Silver or AgNi+CuNi Bimetal layers, each design serves a specific electrical load and assembly requirement.

Core Geometry: Round vs. Square

The choice between round and square contacts often defines your entire production workflow. Round contacts are primarily produced as rivets through cold-heading, while square contacts are typically stamped tips used for high-strength brazing in industrial contactors.

Engineering Advantage of AgNi+CuNi: By utilizing a Copper Nickel (CuNi) base layer, we enhance the welding reliability of the contact while significantly reducing the total usage of precious silver. This bimetal structure is the industry secret for high-performance, cost-effective smart switches.

IATF 16949 Quality Benchmarks

Quality in silver contacts is measured by the stability of Contact Resistance over millions of cycles. At CD Silver, our IATF 16949 certified facility ensures that every AgNi+CuNi contact undergoes ultrasonic testing to verify the bond strength between the silver layer and the base metal.
