Silver Contact Manufacturer Riveting Silver Alloy Contacts on Copper Base
Introduction to AgNi Contact Material: Why It Remains the Industry Standard in 2025
AgNi contact material, also known as silver-nickel alloy contact, is one of the most widely used electrical contact materials in 2025, particularly for low to medium power applications. With nickel content typically ranging from 10% to 30%, AgNi contact material offers an optimal balance of electrical conductivity, mechanical strength, and cost efficiency. According to the World Silver Survey 2025 published by the Silver Institute, AgNi contact material accounts for approximately 50% of global silver alloy consumption in electrical contacts, making it the workhorse of the industry.
Chende Electrical Contact Co., Ltd., a leading AgNi contact material manufacturer in China since 2010, specializes in riveting AgNi contact material on copper base for bimetal and tri-metal designs. Our IATF16949-certified factory produces over 3.8 billion pieces annually, serving automotive relays, household appliances, and industrial switches.

Physical and Electrical Properties of AgNi Contact Material
The superior performance of AgNi contact material stems from its unique microstructure. Nickel particles dispersed in the silver matrix improve hardness and arc erosion resistance while maintaining high conductivity.
| Property | AgNi10 | AgNi15 | AgNi20 | Pure Silver (Reference) |
|---|---|---|---|---|
| Silver Content (%) | 90 | 85 | 80 | 100 |
| Hardness (HV) | 80–100 | 90–110 | 100–120 | 40–60 |
| Conductivity (% IACS) | 85–90 | 80–85 | 75–80 | 100 |
| Density (g/cm³) | 10.3 | 10.2 | 10.1 | 10.5 |
| Contact Resistance (mΩ) | ≤2 | ≤2.5 | ≤3 | ≤1 |
Chende's AgNi contact material consistently achieves these values through advanced powder metallurgy. For detailed test reports, contact us or see our product specifications.
AgNi Contact Material vs AgSnO2 vs AgCdO15/Cu: 2025 Performance Comparison
AgNi contact material excels in low contact resistance and processing, while AgSnO2 offers superior arc resistance for high-power applications. AgCdO15/Cu, though excellent in anti-welding, is being phased out due to cadmium toxicity (EU RoHS Directive).
| Parameter | AgNi Contact Material | AgSnO2 Contact | AgCdO15/Cu |
|---|---|---|---|
| Contact Resistance | Lowest (≤2 mΩ) | Low (≤5 mΩ) | Low (≤3 mΩ) |
| Arc Erosion Resistance | Moderate | Excellent | Good |
| Anti-Welding | Good | Excellent | Excellent |
| Life Cycles (30A AC1) | 100K–500K | 200K–1M | 100K–500K |
| RoHS Compliance | Yes | Yes | No |
Chende recommends AgNi contact material for signal and household relays, transitioning to AgSnO2 for EV applications. See our Silver Contact Materials Ultimate Guide for more comparisons.
