SnZn7Cu3 Babbitt wire is suitable for metal spraying on the end face of metalized film capacitor. Excellent antioxidant and welding performance, enhance the reliability of seaming of the metal spraying layer and CP wire.
The metal spraying of metalized film capacitor is of high adhesive force and low loss angle. It is an ideal spraying materials for the super-miniature capacitor and laminated capacitor.
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
The surface of the Tin Zinc Copper wire is smooth and bright, with no broken wires, no greasy dirty and burrs, no scratches and scars, no jam in the process of use. It conforms to the requirements of EU ROHS, REACH, and relevant domestic laws regulations for environmental protection.
