Contact rivet for electromechanical relay

Wenzhou Saijin Electrical Alloy Co. Ltd. supplies contact rivets designed for electromechanical relays, fabricated in Zhejiang, China. These rivets are composite constructions that combine copper alloy cores with optional surface plating, providing a balance of conductivity and mechanical strength. The design emphasizes reliable electrical contact while tolerating the vibration and thermal cycles typical of industrial equipment. The supplier highlights the flexibility of material selection compared with traditional solid precious‑metal rivets.

Typical industry practice uses copper‑tin or copper‑silver alloys for the core, a material choice that delivers conductivity above 90 % IACS and tensile strength exceeding 500 MPa. Standard dimensions range from 1.5 mm to 3 mm in diameter and 3 mm to 6 mm in length, with gold or nickel plating applied for corrosion resistance. Such specifications align with IEC 60947‑1 requirements for relay components. The composite structure also improves wear resistance, extending service life in automotive and machinery applications.

These rivets are commonly purchased by relay manufacturers, OEMs in automotive electronics, and industrial equipment builders who need consistent contact performance. Suppliers offer flexible minimum order quantities and support shipping terms such as FOB or CIF, with payment options including L/C and T/T. Buyers should confirm the exact plating, dimensions and material grade required for their design before placing an order. The Chinese origin and harbour‑tier verification give additional confidence in supply chain stability.

Wenzhou Saijin Electrical Alloy Co. Ltd. is located at No. 47 Yushan South Road, Haicheng Town, Wenzhou, Zhejiang 325055, China. The company operates as an imported‑tier supplier and has achieved harbour‑tier trust status on the marketplace. Its response metrics show a response rate of 0 % and an average response time of 0 hours, indicating that inquiries may require follow‑up. The firm focuses on alloy‑based electrical components for relay and circuit applications.

The listing does not disclose production capacity, certifications or specific quality management systems, so buyers should request relevant test reports such as IEC 60947 compliance. Wenzhou Saijin emphasizes the composite nature of its rivets, allowing customers to select material grades that match performance and cost goals. Communication channels are limited by the current response statistics, and prospective purchasers are advised to confirm lead times and packaging details directly with the supplier.
