As a 15-year specialized manufacturer of silver contact, bimetal silver contact, tri-metal silver contact rivets and contact assemblies, Chende has delivered more than 3.8 billion pieces worldwide. Today we fully open our internal material database and share the most practical 2025 data.

1. AgNi (Silver-Nickel) Contact – Still the Cost Champion in 2025

AgNi series (AgNi0.15, AgNi10, AgNi15, AgNi20, AgNi30) continues to be the most popular silver alloy contact for low-to-medium power relays and household appliances.

Why 90% of factories still choose AgNi?

• Extremely low and stable contact resistance (≤2mΩ)
• Excellent processing performance – perfect for high-speed automatic riveting
• Best cost-performance ratio – Chende 2025 bulk price: USD 0.011–0.028 per piece (MOQ 10K)
• Easiest to produce as bimetal silver contact strip

Typical specifications: AgNi10/Cu, AgNi15/Cu bimetal rivet, head Ø2.5–10mm, widely used in signal relays, automotive auxiliary relays, wall-hung boiler relays.

2. AgSnO₂ & AgSnO₂/In₂O₃ – The Absolute Mainstream for Export & New Energy
