Why Bimetal Rivets Are the Industry Standard for Silver-Bimetal Rivets Based Electrical Contacts in 2025

Bimetal rivets have become the dominant form of silver-based electrical contacts in modern relay and contactor designs. By combining a silver alloy layer with a copper base, bimetal rivets achieve optimal electrical performance while reducing silver consumption by 40–60% compared to solid silver contacts. In 2025, with silver prices averaging $35/oz (World Silver Survey 2025), bimetal rivets offer significant cost advantages without compromising reliability.As a leading silver contact manufacturer China, Chende specializes in custom bimetal rivets.

AgNi Bimetal Rivets: The Most Popular Choice for General Relay Applications-Bimetal Rivets

AgNi bimetal rivets with 10–30% nickel content remain the most widely used silver-based electrical contacts for low to medium power relays. Advantages include:

• Contact resistance ≤2 mΩ
• Excellent cold welding characteristics
• Good arc erosion resistance under resistive loads
• Easy riveting on copper base

Chende's AgNi10/Cu bimetal rivets are the bestseller for household appliances and automotive auxiliary relays. For AgNi silver-based electrical contacts, see our product catalog.

AgSnO2 Bimetal Rivets: 2025 Standard for EV & High-Power Applications

AgSnO2 bimetal rivets have become the 2025 mainstream for EV chargers and industrial contactors due to RoHS compliance and superior arc resistance. Chende offers doped AgSnO2(In2O3) bimetal rivets with life exceeding 200,000 cycles under 60A load.

Tri-Metal Rivets: Advanced Cost-Saving Design for 2025

Tri-metal rivets (Ag/Cu/Fe) reduce silver consumption by an additional 30% compared to bimetal while maintaining performance. Chende pioneered tri-metal technology for automotive customers in 2018.
