Trimetal Silver Contact Rivets
Products Description
As a professional manufacturer of electrical contact metal solutions under the APOLLO brand for over 30 years, we leverage the technological accumulation of our own factory to launch Trimetal Silver Contact Rivets. With its innovative three-composite structure-silver alloy head and feet combined with a copper core-it redefines the performance and cost balance of electrical contact elements, making it a preferred core component in industrial control relays and other fields.
Product Features and Functions
Innovative Tri-Layer Composite Structure
The OEM Tri-metal Contact Rivet is not made of a single material, but rather employs a precise three-layer composite structure. The head and feet utilize a high-performance silver alloy, ensuring excellent contact resistance and arc-extinguishing capability; the middle layer is highly conductive copper, serving as an efficient current conduction channel.
01
Significant Cost Optimization
Compared to traditional integral silver contacts, our Customized Tri-metal Contact Rivets, while maintaining the performance of key contact surfaces (head and feet), successfully minimize silver usage by using copper in the middle, saving customers up to 30%-50% in raw material costs, achieving a significant leap in cost-effectiveness.
02
Superior Mechanical and Electrical Performance
The silver and copper layers are metallurgically bonded using advanced processes, resulting in extremely high bonding strength. This ensures that the silver layer will not leak, peel, or delaminate under frequent mechanical movements and current surges. The product features low contact resistance, high thermal conductivity, and excellent resistance to arc erosion.
03
Designed for Dynamic Switching
This structure is specifically designed for "moving contacts" requiring left-right swinging or reciprocating motion, such as industrial control relays. The silver layers at both ends ensure that the Silver Tipped Tri-metal Rivets are always made of silver material with optimal conductivity, regardless of how the contacts operate, thus guaranteeing the reliability and consistency of the operation.
04
Advanced Metal Forming and Manufacturing Processes
Cold Forging Technology: We employ a high-precision cold forging process to forge tri-metal composite wire into rivet shapes in a single operation. This process ensures high-dimensional accuracy and consistency, enhances the metal's grain structure, and improves the Head & Foot Silver Plated Contact Rivet's mechanical strength.
Precision Turning and Finishing: After forming, the OEM Tri-metal Contact Rivets undergo precision turning to ensure the geometric accuracy of key components such as the head's spherical curvature and foot dimensions. Subsequent finishing processes result in a mirror-like surface, reducing arc buildup and extending service life.
Comprehensive Quality Control: From raw material warehousing to finished Customized Tri-metal Contact Rivet delivery, every step is rigorously monitored to ensure stable and reliable performance of each batch, fully meeting the specifications outlined in the drawings.
Product Details
Structural Details: As clearly seen in the images, the rivet has a three-layer structure. The top and bottom silver layers have a metallic luster, while the middle copper layer has a distinct color, visually demonstrating the precision of the three-layer composite structure.
Dimensional Details: The differences in diameter and height of rivets of different specifications showcase our strict control over the dimensional tolerances of the Silver Tipped Tri-metal Rivet.
Surface Details: The silver layer surface is smooth, burr-free, and bubble-free. The transition area between the copper and silver layers is free of cracks and delamination, reflecting the stability of the composite and stamping processes.
Process Details: The rounded transition of the Trimetal Silver Contact Rivets head and the flat end face of the foot are achieved through precision machining, ensuring a perfect fit with the relay contact base and reducing contact resistance fluctuations.
