Products Description
AgCuAg Multi-Layer Electrical Contacts are designed specifically for high-end industrial control. Its structure employs a composite technology of silver alloy (Ag) - copper (Cu) - silver alloy (Ag), meaning the contact head and feet are both silver alloy layers, with a copper interlayer in between. This technology is extremely complex, and it represents a cutting-edge product that only a very few domestic companies possess the R&D and production capabilities for. Its design aims to replace costly solid silver contacts, providing a superior balance between cost-effectiveness and reliability.
Core Advantages
Cost Control
Compared to solid silver contacts, the three-composite structure for Trimetal Silver Contacts effectively saves 30%-50% of material costs, significantly reducing the procurement pressure on high-end electrical connectors.
Technical Challenges
Trimetal Composite Rivet Terminals structure requires extremely high manufacturing processes to ensure uniform silver layer thickness and a strong bond with the copper layer, preventing silver layer peeling due to thermal expansion and contraction or high-frequency friction.
Dedicated Function
Trimetal Multi-Layer Riveted Contacts are specifically designed for high-frequency switching components such as industrial control relays, capable of withstanding frequent left and right movements.
Core Challenges of Cold Forging
Control of Synchronous Deformation of Three Layers
Silver alloys and copper exhibit significant differences in rheological stress and plastic deformation characteristics. Uneven deformation distribution during cold forging can easily lead to interlayer misalignment or stress concentration. Therefore, precise control of the mold structure and deformation amount is necessary to achieve synchronous plastic flow of the three layers for AgCuAg Composite Rivet Contacts.
Ensuring Silver Layer Uniformity
The silver layer at the head and foot must maintain continuous coverage to prevent localized copper exposure or uneven thickness due to uncontrolled material flow. Strict requirements are placed on the pre-forming dimensions of the billet and the upsetting ratio to ensure a stable and consistent silver layer distribution after the Trimetal Multi-Layer Riveted Contacts forming.
Interface Bonding Stability
During high-pressure cold forging, the composite interface for Trimetal Composite Rivet Terminals is subjected to complex shear and compressive stresses. Insufficient bonding strength can easily lead to delamination or wrinkling defects. Optimization of interface pretreatment and forming rhythm is required to ensure that the interface remains stable and does not peel off during plastic deformation.
Packaging Method
These Trimetal Silver Contacts employs a tiered protective packaging solution to ensure safety and integrity during transportation and storage. First, Trimetal Composite Rivet Terminals are sealed in an inner vacuum-sealed plastic bag to effectively prevent moisture, oxidation, and dust contamination. It is then placed in an outer corrugated cardboard box for centralized protection. After sealing, the box is reinforced with strapping to enhance overall compression and impact resistance. For bulk shipments, the boxes are neatly stacked on pallets and secured with stretch film. Finally, the pallets are reinforced with strapping a second time to ensure the packages do not scatter or tilt during long-distance transport, meeting the export standards for both sea and air freight.
