Jinchang City Flourishes with JinChuan’s Cutting-Edge Copper Industry

Jinchang’s Copper Renaissance Begins

Nestled in Gansu Province, Jinchang city—renowned as China’s "capital of nickel"—is experiencing a renaissance driven by its abundant copper resources and JinChuan Group’s forward-thinking industry upgrades. As a leading state-owned enterprise, JinChuan has evolved its copper sector from basic raw materials to high-precision, innovative products, cementing Jinchang’s status as a hub of industrial excellence. At the heart of this transformation are the company’s "special-shaped copper strips," a game-changer for modern technology applications.

Special-Shaped Strips Meet Modern Needs

Liu Dong, manager of the semiconductor packaging materials division at JinChuan Niedu Industrial Co., Ltd., explains the innovation: “We call them ‘special-shaped copper strips’ because their surface isn’t flat—it features a raised T-shape.” This unique design has made the strips indispensable in 5G communication equipment, new energy vehicles (NEVs), and consumer electronics, meeting the precision demands of these fast-growing sectors. After three years of dedicated research, JinChuan has refined its extrusion rolling processes, expanding the product line to over 40 distinct types.

Pioneering Technology Boosts Efficiency

The real breakthrough, however, lies in JinChuan’s pioneering technology. Beyond its established extrusion rolling methods, the company developed integrated forging core production equipment, introducing China’s first integrated forging and rolling process. What once took 12 steps to produce can now be completed in a single pass, dramatically enhancing efficiency and accuracy. Liu Dong highlights that these technical advancements have propelled the strips’ production metrics—efficiency and dimensional precision—to a domestically advanced level, setting a new industry standard.

Economic Growth Strengthens JinChuan’s Brand

This innovation is paying off. JinChuan’s high-end forged "special-shaped copper strips" now boast an annual production capacity of 1,200 tons, capturing 50% of China’s domestic market share. The rise of these strips is not just a technical triumph—it’s an economic boon for Jinchang city, fostering growth and reinforcing the "JinChuan brand" in the global semiconductor industry. The company’s success aligns with JinChuan Group’s broader mission, inspired by President Xi Jinping’s call for innovation-driven development, to lead through technological excellence and high-quality output.

Jinchang’s Legacy Evolves with Innovation

As Jinchang thrives, JinChuan’s copper industry is more than a local success story—it’s a testament to how innovation can transform a city’s legacy. From nickel to copper, Jinchang is leveraging JinChuan’s expertise to power the future of technology, one special-shaped strip at a time.
