After the global economic downturn in 2019, and the outbreak of the new crown pneumonia epidemic that swept the world in early 2020, the global manufacturing industry has not been spared from the impact, and China's magnetic materials industry is no exception; in addition, the complicated Sino-US relations and international situation, The epidemic is superimposed on the changes and influence of the external market environment, and the development of China's magnetic industry will face more uncertain factors, and challenges and opportunities will coexist.

    On March 4, 2020, the haze of the epidemic has not yet dissipated. In order to adapt to the development of digital information technology, promote the resumption of work and production and economic recovery, the Standing Committee of the Political Bureau of the CPC Central Committee held a meeting and proposed to accelerate the construction of new infrastructure such as 5G networks and data centers Progress and accelerate the “new infrastructure” process.

    New infrastructure construction (abbreviated as "New Infrastructure"), mainly including the construction of 5G base stations, UHV, intercity high-speed railways and urban rail transit, new energy vehicle charging piles, big data centers, artificial intelligence, and industrial Internet. Involving many industrial chains, it is guided by new development concepts, driven by technological innovation, based on information networks, and facing the needs of high-quality development, providing an infrastructure system that provides services such as digital transformation, intelligent upgrading, and integration innovation.

    Various types of magnetic materials play a vital role in the construction and development of the seven major fields of new infrastructure.
