Products Description
Built on our proprietary precision welding line, the Welded Assembly of Silver Electrical Contacts merges the conductive efficiency of silver with the structural advantages of a copper substrate through a precise spot welding process. These components are specifically designed for the rigorous switching demands of medium and low voltage electrical systems. Fully compliant with electrical component testing standards, they achieve an optimal balance of conductivity stability, arc erosion resistance, and mechanical durability. Customization is available based on your current ratings, load profiles, and installation requirements, supporting applications across industrial controls, automotive electronics, and home appliance systems. With full in-house capabilities for manufacturing all types of relay metal parts, we offer a truly integrated, one-stop solution.
Product Features and Functions
Low Impedance, High Efficiency Conductivity
The Silver Contact Welded Assembly for Contactor uses a high-purity copper substrate paired with silver alloy contacts, resulting in extremely low current transmission loss, effectively reducing equipment operating temperature rise and improving the energy efficiency of electrical control components.
Strong Arc Resistance and Electrical Wear Resistance
The silver contacts use an arc-resistant alloy formula capable of withstanding instantaneous arc impacts during inductive and resistive load switching, extending electrical life.
Compatible and Universal Mechanical Structure
The copper substrate can be stamped into various configurations, including long conductive bars and threaded connecting posts, making it adaptable to multiple assembly methods such as bolt fixing and snap-fit assembly. The Silver Tipped Copper Contact Assembly can also be directly embedded into standard relay housings.
Environmentally Compliant
All materials and welding accessories incorporated in the Electrical Contact Assembly with Silver Welded Tip are RoHS and REACH compliant. The assembly is entirely lead-free and cadmium-free, making it qualified for export certification to overseas markets including Europe and North America.
Material Properties and Advantages
Silver Contact Material
The Electrical Contact Assembly with Silver Welded Tip is manufactured using compliant alloy materials, including silver alloys and pure silver. These materials provide outstanding resistance to arcing, oxidation, and electrical corrosion, making the assembly well-suited for a wide range of electrical load conditions.
Copper Substrate Material
Highly conductive copper provides exceptional electrical and thermal conductivity, combined with good mechanical ductility and the ability to undergo precision stamping and turning. Importantly, copper exhibits extremely low performance loss when subjected to the Contact Welding process.
Environmentally Friendly and Stable Auxiliary Materials
The Silver Tipped Copper Contact Assembly utilizes welding materials and electrode consumables formulated with industry-leading technology. These materials leave no corrosive residue after welding, ensuring long-term protection of the substrate against corrosion.
Competitive Advantages
| Higher Process Maturity | Compared to the simple welding methods of small and medium-sized manufacturers, we use automated precision welding equipment, resulting in significantly higher process stability and finished product yield for our Electric Resistance Welding Silver Contact. |
| Faster Customization Development | With our own molds and processing lines, we eliminate the need for outsourcing, enabling rapid development of non-standard structures and special load contacts for Brazed Electric Contacts, shortening the customer's R&D cycle. |
| Outstanding Cost-Effectiveness | Eliminating middlemen, we provide high-performance Brazed Electrical Contacts at factory prices, while ensuring stable mass production. |
