18 of Guoke Gaofa [2016], and the project of "Manufacturing Technology of High-performance Copper Alloy Special Processing Materials" jointly undertaken by the industry-university-research scientific and technological cooperation team composed of 15 advantages in the field of special copper alloy processing technology in China was approved
.

The project leader is Beijing Nonferrous Metals Research Institute, the project recommendation is China Nonferrous Metals Industry Association, and the project leader is Professor Mi Xujun, vice president of Beijing Nonferrous Metals Research Institute (Huairou), with a total project fund of 83 million yuan and a special fund of 33 million yuan
.

Copper and copper alloys have excellent mechanical and physical comprehensive properties, highlighting electrical conductivity, thermal conductivity, corrosion resistance and mechanical and process forming properties, and are very important structural and functional integrated metal materials
.
Due to the close correlation and irreplaceability of copper and copper alloys with various industries of the national economy such as electronic power, aerospace manufacturing, ship and marine engineering, and home appliances, the research and industrialization development level of copper alloy new materials is an important symbol
of the country's comprehensive industrial capacity.

Although China's refined copper and copper output has ranked first in the world for many consecutive years, China's copper processing industry is large but not strong, mainly manifested in overcapacity of bulk processed materials, dependence on imports of high-end products and new materials, and poor industrial profitability
.
For many consecutive years, the profit margin of the main income of copper processing enterprises above designated size in China has hovered around 3%, and the import volume of high-performance copper and copper alloy special processing materials is about 500,000 tons every year, and the average import price is much higher than the average price
of copper exported by China.
In contrast, China's copper resources are seriously lacking, copper concentrate is more than 70% dependent on foreign countries, and sustainable development capacity is seriously insufficient
.

The research objectives of the "Manufacturing Technology of High-Performance Copper Alloy Special Processing Materials" project are to view the above research background, with large-diameter and highly corrosion-resistant copper alloy pipes for marine engineering equipment, high-performance copper alloy coated wires for high-end electronic equipment, and high-thermal conductivity copper-based heat sink materials, copper-based self-lubricating materials, and copper alloy brake plates for high-speed rail braking systems as research objects, bringing together Beijing Nonferrous Metals Research Institute, Central South University, University of Science and Technology Beijing, Jiangxi University of Science and Technology, Shanghai University, Henan University of Science and Technology, Guangxi University, Dalian Jiaotong University, Chalco Luoyang Copper Co.

formed a joint research team, through the development of copper alloy special processing materials and powder metallurgy copper matrix composite materials basic theory, common key technology and industrialization application research, Establish an industrial research platform for copper alloy special processing materials and an industrialization base for complete sets of manufacturing technology, fill the technical gap of high-performance copper alloy special processing materials in China, realize the industrialization demonstration and application of typical products, and meet the application needs of key fields such as aerospace, electronic information, shipbuilding industry, marine engineering, and high-speed rail transit; At the same time, through the cross-integration and collaborative innovation of materials science, material processing, new material industry and shipbuilding, aerospace, electronics, rail transit manufacturing and other fields, new theory, new technology, new material technology and application technology drive the technological transformation and upgrading of China's copper processing industry, and lay a scientific and technological foundation
for the sustainable development of China's copper alloy processing industry.

Focusing on major scientific issues in six aspects, including the multi-element synergistic mechanism and basic database of the mechanical and physical properties of copper alloy processed materials, the multi-field coupling mechanism in the solidification process of copper alloy, the continuous deformation micro-nanonization effect of tube rods and wires and the evolution law of the second phase structure, the project carried out the design and regulation of macro-microstructure of copper carbon composite material dual network, the design and manufacturing technology of new elastic floating structure of copper alloy powder metallurgy gate, the expansion and tensile integration technology of high-surface quality, high-precision large-diameter and highly corrosion-resistant copper alloy pipe, The research and research of 11 key technical issues, including hot and cold combination molding vertical continuous casting technology, multi-conductive copper alloy non-vacuum continuous casting technology, copper alloy ultrafine wire continuous coating and online continuous deformation heat treatment technology, laid a scientific and technological foundation
for the implementation of the project.
On the basis of completing the special guidelines of the National Key R&D Plan, this project further consolidates the practical level of achievements through applied technology research and industrialization demonstration, reflecting the development purpose
of science and technology "from practice to practice".

After the completion of the project, a number of demonstration lines for the industrialization of copper alloy special processing materials with independent intellectual property rights will be built, and the products will fill the domestic gap and replace imports, build an industrialization platform and talent training base for high-performance copper alloy special processing materials, and drive the technological transformation and transformation and upgrading
of China's copper processing industry.
After the completion of the project, a systematic intellectual property system and an integrated innovation platform for production, education and research will be established to achieve high performance and high added value of copper and copper alloy products, which is of great significance
for enhancing the overall competitiveness of China's copper and copper alloy industry and meeting the urgent needs of innovation and development of China's high-end manufacturing and strategic emerging industries.
