SnZn7Cu3 Babbitt wire is suitable for metal spraying on the end face of metalized film capacitor. With strong adhesive force, good weldability and low loss angle, it is an ideal metal spraying material for laminated capacitors.
Since the official implementation of EU "RoHS" instruction on July 1st, 2006, leaded metal spraying materials were forbidden in a short period of time. The performance and quality of the lead-free metal spraying materials of Tianlong are the same as or superior to the similar overseas products. The capacitors produced by the company have been widely used in high-speed rail, automobiles, new energy, and aerospace fields.
