Performance Characteristics

Arc Erosion Resistance

Dispersed metallic oxide particles restrict material transfer and surface pitting during high-current switching cycles.

Anti-Welding Capability

Prevents contact sticking under high inrush currents and short-circuit fault conditions.

Electrical Resistivity

Low bulk resistivity minimizes thermal generation and ohmic losses during continuous current conduction.

Mechanical Formability

Ductile base metal combined with strong interfacial bonding allows severe bending, stamping, and shearing without edge cracking.

Manufacturing Process

Surface Preparation: Chemical cleaning and mechanical brushing remove surface oxides and contaminants from base and precious metal wires.

Solid-Phase Roll Bonding: High-pressure mechanical rolling unites dissimilar metals at ambient or elevated temperatures to initiate atomic diffusion.

Diffusion Annealing: Controlled thermal treatment in protective reducing atmospheres strengthens the metallurgical bond across the interface.

Precision Cold Rolling: Sequential passes through high-precision rolling mills achieve final specified thickness and mechanical temper.

Slitting and Conditioning: Rotary slitting to exact width dimensions followed by edge deburring for smooth feeding into stamping dies.

Application Areas

Miniature Circuit Breakers (MCBs)

Fixed and moving contact components requiring reliable short-circuit interruption.

AC Contactors and Relays

Electromagnetic switching mechanisms handling frequent electrical loads.

Thermal Overload Relays

Stable contact resistance for precision bimetallic trip mechanisms.

Automotive Switches

FAQ

Q: What is the primary advantage of using silver alloy contact strips over solid silver contacts?

A: Clad strips combine the electrical performance of silver alloys at the functional contact point with the lower cost and structural strength of copper backing, significantly reducing material costs.

Q: How do you ensure the silver layer does not separate from the base metal during stamping?

A: Solid-phase roll bonding and controlled diffusion annealing create a strong metallurgical bond that withstands severe mechanical deformation without delamination.

Q: Can you supply custom strip cross-section profiles based on our proprietary tooling?

A: Yes, engineering teams review client drawings to manufacture custom inlay and overlay profiles tailored to specific progressive die requirements.

Q: What is the standard lead time for bulk production orders?

A: Standard production runs range from two to four weeks depending on alloy availability, dimensional complexity, and order volume.

Q: Are your silver alloy contact strips compliant with environmental regulations?

A: Manufacturing processes comply with RoHS and REACH standards regarding restricted hazardous substances.
