Premium Eco-Friendly Lead-Free Metal Wire for Capacitor Performance

Product Description

SZSC series of products is an alloy wire with Sn-Zn-Sb-Cu, a proper amount of improvement elements are added to the tin zinc-based alloy to inhibit oxidability. Various studies show that the current speed can be reduced. Improving the performance of the alloy and wire is wildly applied with high-cost performance.

The 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.


The surface of the 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.

Product code:SZSC
The products of this series have been authorized patent, one who counterfeits them will have to assume lawful responsibilities.

Our company make a various of SZSC products,SZSC-1,SZSC-2A,SZSC-2B,SZSC-3, SZSC-4, SZSC-5, SZSC-6, SZSC-8.Can help the customer reduce the cost one by one. It is one of the best underlayer metal spraying materials for the pure aluminum film.
