Product Description

Product Description

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

Tin Zinc Copper alloy wire is the best film capacitor metal spraying material.
The surface of the Tin Zinc Copper wire is smooth and bright, with no broken wires, no greasy dirt, and burrs, no scratches and scars, and no jam in the process of use. It conforms to the requirements of EU ROHS, REACH, and relevant domestic laws and regulations for environmental protection.
