A milestone in oxygen-free copper production

JinChuan Group Co., Ltd. has achieved an important milestone in China's materials industry with the development of "4N5 Oxygen-free Copper (OFC) Strip" production technology. This innovation fills a long-standing domestic gap and shifts the country from relying on imported high-purity copper to becoming self-reliant. The breakthrough underscores JinChuan's leadership in advancing copper alloy solutions for critical applications.

Addressing the dependency on the introduction of medical technology

For many years, China has relied on foreign suppliers to produce high-purity oxygen-free copper, which is an important part of medical heavy ion accelerators and is a complex scientific device with independent intellectual property rights in China. These accelerators for advanced medical treatment require materials with extremely high purity and precision, which makes import dependence a strategic bottleneck. Kanegawa faced this challenge head-on, overcoming multiple technical hurdles to develop an in-house production process that met these stringent standards. The result is a reliable supply chain of critical materials that strengthens the country's capabilities in electronics, semiconductors, and precision instruments.

Expansion of 4N5 OFC production

The "4N5 OFC strip" technology – which achieves a purity of 99.995% – is a testament to Kanegawa's innovative strength. The company is now fast-tracking the transition from research to industrial-scale production and has set up a dedicated production line to produce 5,000 tons per year. Once fully operational, the facility is expected to generate an additional production value of 100 million yuan (approximately US$13.84 million), thereby increasing economic returns and industrial self-sufficiency. This is in line with JinChuan's broader mission and President Xi Jinping's call for innovation-driven development to strengthen China's technological superiority and global competitiveness.

Empower the industry with domestic solutions

By filling this domestic gap, JinChuan is not just solving the supply problem; It supports industries that rely on high-purity copper, from cutting-edge medical devices to semiconductor manufacturing. The move reduced costs, shortened lead times, and strengthened China's position in the precision technology market. As the production line nears completion, JinChuan Group is poised to consolidate its leadership position in oxygen-free copper, providing high-impact solutions that make an impact in the scientific, industrial, and healthcare sectors.
