CTOnews.com February 16 news, China CRRC high conductivity copper matrix composite "Super Copper" recently appeared in CCTV News "focus interview" column, this material is jointly developed by CRRC Research Institute and Shanghai Jiaotong University Zhang Di team, using the excellent electrical conductivity and mechanical properties of graphene and copper sheet stacked to make a new type of composite material-"super copper", realizing the complementary advantages of graphene and copper.

The super copper test of the only mass-produced high conductive metal composite material in the world has been initially completed before. Replacing the super copper material in the simulation calculation based on application verification can reduce the copper consumption of 20KW motor by 12.33%. The experimental results show that the electrical conductivity of super copper is more than 10% of silver. If 10% of the country's motors were made of this "super copper" material, more than 18 billion kilowatt-hours of electricity could be saved a year, equivalent to a Gezhouba power station (which generated 17.434 billion kilowatt-hours of electricity in 2022).

CTOnews.com learned that at present, the high conductivity copper matrix composite "super copper" has completed the pilot test, verified the feasibility of mass production of super copper, and realized small batch production. CRRC Research Institute will continue to promote the development process of "super copper", increase investment in basic research and development, and speed up the process of batch industrial manufacturing.
