Introducing the SZSC series, a pioneering alloy wire composed of Sn-Zn-Sb-Cu. By incorporating targeted improvement elements into this tin-zinc-based alloy, we effectively curb oxidability. Extensive research indicates a notable reduction in current speed, significantly enhancing the alloy's performance. Our wire, celebrated for its high cost-effectiveness, is widely utilized across numerous applications.
This exceptional wire is specifically engineered for metal spraying on the end face of metallized film capacitors. With unrivaled adhesive strength, exemplary weldability, and a minimal loss angle, it stands as the quintessential metal spraying solution for laminated capacitors, ensuring optimal performance.
Following the EU 'RoHS' directive enacted on July 1st, 2006, lead-based metal spraying materials faced swift prohibition. Tianlong's lead-free metal spraying materials boast performance and quality on par with, or surpassing, international counterparts. Our capacitors are extensively employed in advanced sectors such as high-speed rail, automotive, new energy, and aerospace industries.
Our wire boasts a flawlessly smooth and lustrous surface, devoid of breaks, grease, or burrs, and free from scratches or scars. It ensures seamless usage without jams and adheres strictly to EU RoHS, REACH, and pertinent domestic environmental protection laws and regulations.
