Silver Alloy Bimetal Contact Point
Products Description
A Silver Alloy Bimetal Contact Point typically consists of two parts:
Silver Alloy Contact Layer: Responsible for the arc-bearing area during actual conduction and interruption.
Copper Base Layer: Provides structural support, thermal conductivity, and weld/riveting compatibility.
Depending on the application structure, the product can be categorized as:
Moving Contact Tip
Fixed Contact Tip
Contact Rivet Type
Flat Contact Assembly
Custom Shaped Contact Point
Supports riveting, welding, embedded, and automated assembly structure designs, adapting to different electrical system structural requirements.
Application Advantages: Empowering the Core Supply Chain of Industrial Control and General Electric
General-Purpose & Industrial Relays
As the core of the system, they withstand high-frequency, fault-free opening and closing under medium-power loads.
Snap-Action Thermostats
Widely used in small household appliances, HVAC systems, and motor protection, achieving instantaneous response and high-frequency switching under minimal mechanical force.
Miniature Circuit Breakers (MCBs)
As auxiliary moving/stationary contacts in low-voltage power distribution systems, they ensure safe isolation during daily power distribution and overload tripping.
Detailed Showcase: The Engineering Aesthetics of the Microscopic Interface
Seamless Metallographic Interlocking
Under a high-powered microscope, the longitudinal section of the Riveting reveals a perfect metallurgical bond between the silver alloy (bright white) and the copper (purplish-red), exhibiting either wavy or straight lines. There are no black oxide inclusions or voids, demonstrating the pinnacle of composite processing technology.
Precise Control of the Silver Layer Interface
Even after cold forging, the silver layer thickness remains highly consistent across different areas of the for Electric Power's working surface. No instances of "exposed copper" or "too thin silver layer" due to uneven metal flow occur, ensuring precise control over electrical life.
Perfect Plasticity of the Base Assembly
As a Contact, the copper base exhibits a uniform flared edge after simulated riveting testing. The surface is free of cracks and burrs, adhering tightly to the substrate, showcasing the excellent assembly and processing performance of the underlying material.
Material Advantages
High-performance silver alloy layer
Preferred alloys include AgNi, AgSnO, and AgZn, providing excellent conductivity, resistance to arc erosion, and resistance to welding.
High-conductivity copper substrate
High-quality oxygen-free copper or phosphorus-deoxidized copper, ensuring excellent thermal conductivity and machinability.
Interface compatibility
Material thermal expansion coefficient matching design reduces stress accumulation under temperature cycling.
Environmentally compliant materials
Strictly compliant with international standards such as RoHS and REACH, supporting the global market for high-end electrical equipment.
