Bimetal Rivet Contacts

Bimetal Rivet Contacts

Bimetal Rivet Contacts are composite electrical contact elements that permanently bond two different metals (typically a highly conductive silver alloy and a highly supportive copper) using a precision solid-state welding process. Their core design logic is to precisely apply expensive, high-performance contact materials to the electrical contact surface within a single contact point, while the remaining structure is supported by a lower-cost, mechanically superior base metal, thus achieving an optimal engineering balance between performance, reliability, and cost.

Products Description

 

Bimetal Rivet Contacts

Bimetal Rivet Contacts employ a composite structure design of silver alloy and copper. This material combination is not a simple physical superposition, but rather a molecular-level bond between the metals achieved through precision metallurgical processes, forming a stable bimetallic system. Visually, the component presents a cylindrical or irregular shape, with a riveting mounting area at one end and an electrical contact surface at the other. The internal silver alloy layer provides conductivity, while the external copper substrate provides structural strength and heat dissipation.

 

Main Function


Establishing and Maintaining Low-Resistance Electrical Contact: The silver alloy working surface ensures a stable, low-loss current path during each closure for Electrical Relay Silver AgSnO2/Cu Bimetal Rivets.

 

Safe Disconnection and Arc Extinguishing: The silver alloy material for Electrical Contact Points for Breaker resists arc erosion during disconnection, preventing contact welding and adhesion, and ensuring reliable circuit isolation.

 

Mechanical Support and Heat Dissipation: The copper substrate acts as a structural framework and heat sink, ensuring the mechanical stability of the Bimetal Contact Buttons for Relays and promptly dissipating harmful heat from the contact area.

Detailed Display

Material Details

 

The silver alloy layer of Electrical Alloy Silver Copper Combination Rivets has a uniform and bright color, free of impurities, black spots, and color difference; the copper base is purplish-red with a consistent luster, dense and non-porous, with burr-free edges, and excellent electrical and thermal conductivity.

Composite Interface Details

 

The silver-copper interface is seamless, without delamination, gaps, or bubbles, exhibiting a tight metallurgical bond. Magnified observation reveals a smooth interface free of impurities, ensuring lossless electrical and thermal conductivity for AgNi Bimetal Contact Rivets.

Structural Details

 

The rivet heads are neat and flat, the shanks are straight and smooth, integrally molded without splicing, with precise dimensions, compatible with standard riveting holes, convenient assembly, and strong interchangeability for Silver Tin Oxide Electrical Contact.
