What are the Silver Alloy Rivets?
Silver Alloy Rivets are used as current-carrying contact elements in relay moving springs, low-voltage contact assemblies, contactors, and circuit-control mechanisms where the contact head and fixing shank must be produced with a controlled rivet geometry. The available material route includes pure silver and silver-alloy systems, with alloy selection matched to electrical load, arc exposure, contact force, and switching frequency. Custom rivet head diameter, shank diameter, overall height, and other drawing-controlled dimensions can be developed for production volumes ranging from engineering samples to repeat orders.
Material Characteristics of Solid Silver contacts for electrical
AgSnO2 Composition & Anti‑Arc Properties
Silver Tin Oxide (AgSnO2) matrix structures suppress material transfer during heavy current switching cycles, preventing premature contact degradation in high‑inductivity loads.
Electrical Conductivity & Thermal Performance
Maintains low electrical resistivity below 2.0 micro‑ohm centimeters, minimizing power loss and operating temperature spikes inside compact molded case circuit breakers.
Hardness & Mechanical Wear Resistance
Optimized work‑hardening during cold extrusion provides surface hardness ratings between 90 and 130 HV, resisting mechanical impact wear during repetitive closing operations.
Advanced Cold Heading Manufacturing Process of Silver electrical contacts
Multi‑Station Precision Forming
Utilizes automated multi‑die cold formers to shape wire stock into precise rivet configurations without material waste, securing consistent batch uniformity.
Micro‑Spot Welding & Cladding Control
Applies automated projection welding and solid‑liquid composite cladding technologies to ensure exact precious metal layer thickness on the working face.
In‑Line Optical Inspection
Employs high‑speed optical sorting systems to detect dimensional defects, flash, and surface cracks before packaging and dispatch.
Cleanroom Surface Passivation
Chemical and electrolytic cleaning removes residual lubricants and oxides, ensuring clean contact surfaces ready for subsequent assembly operations.
Downstream Applications and Integration
