The high-end copper alloy pipe production line in Guilin, Guangxi is completed and will become the largest production base in South China.

China News Service, Guilin, Guangxi, November 10th (Yang Chen, Deng Junbin) Guangxi Guilin Lijia Metal Co., Ltd. held a completion ceremony for a 16,000-ton copper-based new material production line technology upgrade project on the 10th. After the project reaches capacity, it will become the largest high-end copper alloy pipe production base in South China.

Copper processing is China's dominant industry. In 2025, China's comprehensive output of copper processed pipes will be 21.54 million tons, ranking first in the world. However, in the field of high-end alloy pipes and bars, there is still a gap between supply capacity and demand.

Li Zhou, dean of the School of Materials Science and Engineering at Central South University, said that the technical transformation project of Guilin Lijia Company is targeting the above-mentioned weak links to accurately fill the gaps. It is based on the positioning of high-end copper alloy materials in high-end scenarios such as ships and deep-sea equipment, and focuses on high-performance copper-based new material technology research.

"After the project is put into operation, it will further enhance China's stable supply capacity of high-precision and high-reliability copper alloy tubes and bars, and help the copper processing industry upgrade from scale advantages to quality and technological advantages." Li Zhou said.

"The biggest change brought about by the new production line is the exploration of the product matrix." Liang Jianhua, general manager of the marketing center of Guilin Lijia Company, said that in 2025, the company's sales revenue of white copper tubes exported to Europe will increase by 22.3% year-on-year, and orders for high-end white copper tubes from members of the Regional Comprehensive Economic Partnership Agreement (RCEP) are growing rapidly. After the completed technical transformation project is put into production, high-precision, large-sized customized alloy copper pipes will be mass-produced on a large scale, further enhancing product competitiveness.

On the same day, Guilin Lijia Company signed cooperation agreements with the team of Academician Xie Jianxin of the University of Science and Technology Beijing and Central South University respectively, focusing on key processes and core materials of high-end copper-based materials to carry out collaborative industry-university-research research.
