Recently, the technical innovation of China Aluminum Luoyang Copper Co., Ltd., which is owned by China Aluminum Corporation, has achieved new results. The company has undertaken research and development of “high-performance chromium bronze and nickel white copper modified research†and “copper alloy X material and technology research†, "Development of large-caliber white copper tubing" 3 projects passed the national acceptance; "thin-wall tube precision continuous casting forming technology development and industrialization projects" through industry experts.
   After a rigorous review by the acceptance expert group, it is believed that the performance of the three products developed by Chinalco Luotong Copper Co., Ltd. “High-performance Chrome Bronze and Nickel-nickel-nickel-copper modified †, “Cu alloy alloy No. X material and process research†and “Development of large-caliber white copper pipe materials †All of them meet the requirements of the subject index and form a batch production capacity; they believe that the "thin-wall tube precision continuous casting forming technology" has the advantages of short flow, low cost, and high overall yield, and can produce high-quality, large-volume-weight and ultra-long-length light. Pipes have a broad market prospect.
