Products Description
Superior Material Combination: Composed of silver alloy and copper wire, these Bimetal Contact Buttons for Relays offer excellent electrical conductivity and durability. The silver alloy ensures low contact resistance, while the copper wire provides mechanical strength.
Precision Engineering: Manufactured with advanced cold heading techniques, our Electrical Relay Silver AgSnO2/Cu Bimetal Rivet buttons guarantee consistent performance and long-term stability in relay applications.
Production Steps
Material Selection and Preparation: First, our Silver Coated Electrical Contacts select high-quality silver alloy and copper wire. The copper wire is cut to the appropriate length, and the silver alloy is prepared in the form required for the contact layer.
Cold Forming Operation: The prepared materials undergo the cold forming process. This process shapes the copper wire and fuses the silver alloy onto it to form the composite Electrical Silver Contact Point. The cold forming process is carried out using specialized machinery that ensures the precise shape and dimensions of the contact button.
Quality Inspection: After cold forming, each Cold Forming Process Contact button undergoes a rigorous quality inspection. We check for dimensions, surface finish, and material integrity. Any contact button that does not meet our quality standards is rejected.
Finishing and Packaging: The Silver Coated Electrical Contacts are then subjected to finishing operations such as cleaning and polishing (if required). Finally, they are packaged in a way that protects them from damage during storage and transportation.
Microscopic Structure
Interface Between Silver Alloy and Copper
Under a microscope, the interface between the silver alloy and copper in our Electrical Silver Contact Point is clearly defined. The bonding between the two materials is strong, ensuring that there is no delamination during use.
Grain Structure of Materials
The silver alloy and copper wire have distinct grain structures. The cold forming process affects these grain structures, aligning the grains in a way that enhances the mechanical properties of the Cold Forming Process Contacts.
Surface Micro-Roughness
The surface of our composite contacts has a controlled micro-roughness. This micro-roughness is beneficial for electrical contact as it increases the effective contact area between the contact button and other components in the relay.
Inclusion-Free Materials
Our Electrical Relay Silver AgSnO2/Cu Bimetal Rivets are made from materials with minimal inclusions. Inclusions can act as stress concentrators and affect the electrical and mechanical properties of the contact button.
