As a substitute for pure silver tape, precious metal composite tape is widely used in low-voltage electrical appliances and fuses. It not only maintains the fast fusing property of the original silver strip, but also saves the material cost, and is an ideal material to replace the fusing of pure silver. Zhejiang Songfa Composite New Material Co., Ltd. is a high-tech enterprise integrating R&D, production and sales of silver-copper strips, composite materials, fuse strips, copper-stainless steel composites and other materials. Since its establishment, it has insisted on independent development and insisted on developing the market with scientific and technological innovation. The applications of our copper-aluminum composite, switch silver contacts, relay silver contacts, silver-copper strips, copper-stainless steel composites, fuse links, copper-steel composites, composite materials, silver-copper profiles and other products cover high and low voltage electrical appliances, electronics, communications , home appliances and other fields.
