Unlike full-surface clad materials, our edgelay clad strip features a selective metallurgical bond of premium precious metal layers only along the critical contact edge of a durable base alloy substrate. This targeted design maximizes the utility of costly precious metals, while delivering exceptional bonding strength, delamination resistance, and consistent electrical performance in high-cycle, high-demand operating environments. Our advanced bonding technology creates a unified material structure that outperforms mechanically attached edge contacts and electroplated alternatives, with a stable monthly production capacity of 30 tons to support scalable, custom supply for industrial component manufacturers and specialized electrical equipment producers globally.
Our Edgelay Clad Metal Strip is fully customizable to match your precise edge-contact requirements, with core standard parameters detailed below:
Parameter | Standard Range | Customization Options |
Edge Clad Layer Material | Gold, gold alloy, pure silver, silver-nickel, silver-copper, silver cadmium oxide, silver tin oxide | Custom alloy blending for targeted contact performance |
Base Substrate Material | Pure silver, silver alloy, copper, brass, phosphor bronze, beryllium copper, nickel silver, nickel, iron, stainless steel, Monel | High-strength alloy matching for complex forming processes |
Edge Clad Layer Thickness | 0.02–1.0 mm | Ultra-precision thickness tolerance control |
Edge Clad Layer Width | Standard industrial edge dimensions | Custom clad width from 0.5 mm upwards |
Base Substrate Thickness | 0.05–3.5 mm | Graded thickness for specialized stamping and forming |
By applying precious metals only to the functional contact edge where electrical performance is required, our Edgelay Clad Metal Strip delivers dramatic cost reductions compared to full-surface clad or solid precious metal materials, with zero compromise to critical contact performance.
The metallurgical bond between the edge clad layer and base substrate eliminates the risk of contact displacement, delamination, or fatigue failure common with soldered or riveted edge contacts, ensuring stable performance through millions of operating cycles.
The precision edge clad layer delivers consistent low contact resistance, excellent arc resistance, and superior corrosion resistance exactly where it is needed most, minimizing temperature rise and extending the service life of your switch and contact components.
Our edgelay clad strip eliminates the need for secondary contact attachment processes like soldering, riveting, or spot welding in your production line, enabling high-speed stamping and forming of integrated contact components with fewer production steps and lower labor costs.
Our Edgelay Clad Metal Strip is the preferred solution for industrial applications with edge-only contact requirements, including precision switch systems (slide switches, snap-action switches, push-button switches, miniature micro-switches), circuit protection systems (circuit breakers, overload protectors, safety switch components), thermal control equipment (thermostat contactors, temperature regulator switches, limit switches), automotive electronics (edge-contact sensors, vehicle control switches, automotive relay edge contacts), and communication equipment (precision signal switches and connector contact components).
Our edgelay clad strip features precious metal bonding only along the functional contact edge, while overlay clad materials offer full-surface precious metal coverage. Edgelay solutions deliver greater cost efficiency for edge-only contact applications, while overlay solutions are ideal for full-surface conductive requirements.
We offer custom clad edge widths starting from 0.5 mm, with full flexibility to match the exact contact dimensions required for your component design.
Yes. Our clad strip is engineered to be compatible with standard high-speed stamping, forming, and slitting equipment, requiring no specialized machinery for component fabrication.
Every production batch undergoes rigorous testing, including bonding strength verification, thickness precision measurement, conductivity testing, and corrosion resistance analysis, to ensure full compliance with your specifications and global industrial standards.
