TCPR Group was founded by a team of high-level overseas returnees, specializing in the R&D and production of ultra-high-purity metal materials for chip manufacturing. The company has overcome critical "bottleneck" technologies, achieving world-leading standards in materials such as 6N aluminum, 6N tantalum, 7N copper, and 5N manganese. These products have entered the supply chain for internationally advanced process chips, supporting China's cutting-edge chip manufacturing and the raw material needs of semiconductor precision components. The group provides crucial strategic support for the secure and controllable full-chain requirements of China's semiconductor industry.

TCPR Group has independently developed core technologies and equipment for producing ultra-high-purity metal materials. It has established modern production lines with complete intellectual property rights for ultra-high-purity aluminum, tantalum, copper, manganese, and special aluminum alloys, building a self-sufficient upstream and downstream industrial chain. The group has created a highly influential large-scale industrial base spanning from tantalum ore refining to tantalum products for chip manufacturing. This has fundamentally transformed the long-standing dependency on imported ultra-high-purity metal materials, positioning Tongchuang Purun as a leading domestic enterprise with advanced technology that has successfully entered the international market.
