Products Description
Our solid Silver Contact are precision-manufactured from a single material, utilizing advanced alloy systems including 99.99% high-purity silver, silver-nickel alloy (AgNi10), silver-tin oxide (AgSnO), composite silver metal oxide (AgSnO2In2O3), and silver-cadmium oxide (AgCdO). They are specifically designed for applications with stringent requirements for conductivity, arc resistance, and mechanical strength. This product is suitable for industrial control relays, contactors, and switching equipment requiring medium-to-high load switching, frequent operation, and long lifespan, making it an ideal choice for those seeking ultimate performance and stable operation.
Material Advantages: Scientific Ratio of Pure Silver and Alloy System
99.99% High-Purity Silver
Possesses exceptional electrical and thermal conductivity, extremely low contact resistance, suitable for signal transmission, low current applications, and high-precision circuits sensitive to resistance for Silver contacts.
01
Silver-Nickel Alloy (AgNi10)
Building upon the excellent conductivity of silver, the addition of nickel significantly enhances mechanical strength and solderability, balancing wear resistance and conductivity, making Alloy Silver contacts suitable for medium current, high operating frequency applications.
02
Silver-Tin Oxide Series (AgSnO, AgSnO2In2O3)
Oxide particles are uniformly distributed within the silver matrix, effectively inhibiting arc erosion, reducing material transfer, exhibiting outstanding solderability, being environmentally friendly and heat-resistant, especially suitable for AC loads and industrial control environments with frequent switching for electrical contacts.
03
Silver cadmium oxide (AgCdO)
Although it is gradually being replaced by cadmium-free materials, it still has excellent corrosion resistance and stability in some high surge current and high arc scenarios.
04
Application Value: Precisely Matching High-End Industrial Control Needs
Industrial Control Relays and Contactors
Used in PLC output modules, motor starters, and automation equipment control circuits, handling signal conversion and load switching to ensure continuous and stable Alloy Silver contacts line operation.
Power Control Equipment
Applied in new energy power distribution, charging pile control, transformer voltage regulation, and other applications, handling high voltage and current switching requirements for Silver Contact Points.
Safety and Protection Devices
Provides stable and error-free operation in protective relays and safety switches requiring high-reliability disconnection for electrical contacts.
Production Process and Quality Assurance
We implement full-process control from the material smelting stage:
High-purity raw materials: We select silver and alloying elements from internationally renowned suppliers to ensure quality at the source for Silver contacts.
Precision forming: We employ multi-station stamping or cold forming, combined with optical inspection to control dimensional tolerances.
Full inspection and testing: Each batch undergoes sampling metallographic analysis, hardness testing, and conductivity verification, and we provide relevant material reports conforming to ISO standards for Alloy Silver contacts.
Optimized heat treatment: We eliminate internal stress and adjust grain structure through atmosphere-protected annealing to balance hardness and conductivity for electrical contacts.
Surface treatment: We offer polishing, cleaning, or passivation treatments to ensure clean, uncontaminated contact surfaces for Silver Contact Points.
