June 6, 2025 — Zhejiang Winjoy New Material Co., Ltd. (hereinafter referred to as “Zhejiang Winjoy”) has officially signed a cooperation agreement with Germany’s SMS Group, a global leader in metallurgical equipment, to introduce two high-performance precision copper strip mills. These new mills will serve as the core equipment for Zhejiang Winjoy’s high-performance copper strip production line, further solidifying its leading position in the high-precision copper alloy sheet and strip sector and driving independent innovation and industrial upgrading in China’s high-end copper alloy materials.

Powerful Collaboration to Build a World-Class Copper Strip Production Line

The newly imported SMS precision copper strip mills feature globally leading rolling technology and intelligent control systems, offering core advantages such as high strength, superior surface and dimensional accuracy, and high-speed production. They will meet the stringent demands of strategic emerging industries, including new energy vehicles, 5G communications, and high-end electronics, for high-performance copper alloy materials. The mills will significantly enhance Zhejiang Weijing’s production capabilities in ultra-thin, high-conductivity, and high-strength copper strips, helping the company overcome key material “bottleneck” technologies, achieve import substitution, and strengthen the global competitiveness of China’s high-end copper alloy materials.

Focusing on High-End Copper Alloys to Lead Industry Innovation

As a leading Chinese manufacturer of high-performance copper alloy sheets and strips, Zhejiang Winjoy has long been dedicated to the R&D and production of premium copper materials, including nickel silver (C7521, C7701), phosphor bronze (C5191, C5210, C50715), high-copper alloys (C10100, C10200, C14415, C15100), and high-performance copper alloys (C18150, C7025, WK70351, WK72901).
