Introduction Relay performance heavily depends on contact materials, which directly impact electrical conductivity, durability, and resistance to arcing. While traditional materials like pure silver, copper, or silver-cadmium (AgCd) have been widely used, silver alloy contacts are now leading the industry due to their superior performance. At MEISHUO, we utilize high-performance silver alloy in our relays, ensuring longer lifespan, lower contact resistance, and enhanced reliability for demanding applications.                                                                                                                                                                                                                                                               The Evolution of Relay Contact Materials 1.Pure Silver (Ag)

• High conductivity but prone to welding and oxidation.
• Limited lifespan in high-current switching.

2.Silver-Cadmium (AgCd) & Silver-Nickel (AgNi)

• Better arc resistance than pure silver.
• Cadmium is toxic, leading to environmental restrictions (RoHS compliance issues).

3.Silver-Tin Oxide (AgSnO₂) & Silver-Zinc Oxide (AgZnO)

• Excellent arc resistance and anti-welding properties.
• Used in high-load applications like automotive and industrial systems.

4.Silver Alloy (Our Choice – e.g., AgCu, AgPd, or Proprietary Blends)

• Superior conductivity and mechanical strength.
• Lower contact resistance than pure silver or oxide-based materials.
• Enhanced resistance to erosion and material transfer, extending relay lifespan.
