What are Silver Cadmium Contacts?
Engineered specifically for high‑stress switching devices, these Silver Cadmium Contacts deliver dependable performance under severe electrical and thermal loads. Our AgCdO components combine high electrical conductivity with exceptional resistance to arc erosion and contact welding. Operating as an established direct‑source factory, we utilize precision automated cold heading and continuous welding lines to supply global manufacturers of industrial contactors, heavy‑duty motor starters, and high‑current power relays. Every production batch undergoes rigorous mechanical shear testing and microscopic structural analysis to ensure consistent bonding strength and electrical lifespan.

Core Merits & Inherent Material Limitations of AgCdO Bimetal Silver Rivet Contacts
Superior Anti‑Arc Erosion Performance
The decomposition of cadmium oxide during arcing absorbs thermal energy and generates a gas cushion that effectively quenches electric arcs, significantly extending operational lifespan.
Excellent Resistance to Contact Sticking
Silver Cadmium Electrical Contact demonstrates outstanding resistance to material transfer and micro‑welding when subjected to high inrush currents in inductive motor loads.
Environmental and Regulatory Constraints
Silver Cadmium Oxide Agcdo Electrical Contacts are subject to strict regional environmental directives such as RoHS and REACH restrictions regarding cadmium content, requiring careful market evaluation for non‑exempt consumer applications.
Thermal Degradation at Extreme Loads
AgCdO Bimetal Silver Rivet Contacts are prone to cadmium oxide depletion and surface hardening under continuous ultra‑high temperature exposure, necessitating precise thermal management in enclosed device housings.
Manufacturing Process of Silver Cadmium Oxide Bimetal Contact Rivets
Material Preparation：
The first stage is verification of the silver-cadmium material grade against the approved specification. Material identity, composition, and incoming condition should be checked before forming or composite processing.
Contact Forming：
Depending on the contact construction, Silver Cadmium Oxide Bimetal Contact Rivets use AgCdO material that can be processed into contact points or integrated into a composite contact structure.
Dimensional Inspection：
The finished geometry of AgCdO Electrical Contact Rivet should be checked against the approved drawing.
Final Quality Control：
Final inspection for Silver Copper Composite Rivet Contact should cover appearance, dimensions, material identification, and application‑specific electrical or mechanical testing.
