What is permanent magnetic material (hard magnetic material)

​After being magnetized, the permanent magnetic material still retains its magnetism after removing the external magnetic field.

What is soft magnetic material

​Refers to those materials that are easy to magnetize and can be magnetized repeatedly, but when the magnetic field is removed, the magnetism disappears.

What is smart material

​Smart materials are the fourth generation of materials after natural materials, synthetic polymer materials, and artificially designed materials.

What are energy materials

​Energy materials mainly include solar cell materials, hydrogen storage materials, and solid oxide battery materials.

What is superconducting material

​When the temperature drops to a certain critical temperature, the resistance of some materials disappears completely.

What is a new composite material

The straw-enhanced clay used from ancient times to the present and the reinforced concrete that has been used for hundreds of years are both composites of two materials.

Brief introduction of new materials

​With the development of science and technology, people have developed new materials based on traditional materials and the research results of modern science and technology.

New material development

One of the important driving forces for the progress of human civilization has also promoted the development of technology and the upgrading of industries.

What is new material

​New materials refer to newly developed or developing structural materials with excellent properties and functional materials with special properties.
