Physical Properties

When the metal material doped with rare earth elements, the functions of the material in terms of mechanics, magnetism, optics, catalysis have been significantly improved. Therefore, rare earth elements, as an important industrial additive, can improve product performance and optimizing product structure. The properties of metal materials determine their use and applicability. The physical properties of metal materials refer to the performance of metal materials under various physical conditions. Including density, melting point, thermal conductivity, electrical conductivity, thermal expansion, and magnetic properties. Performing performance testing and microstructure analysis on metal raw materials or finished products can provide reliable guarantees for material design and product development, and can also provide references for material procurement, processing and use.

Physical Properties


The significance of surface testing

Currently, most communication, permanent magnet materials and optical equipment are made of rare earth metal materials. The physical properties of rare earth metal raw materials, finished or semi-finished products and the analysis of the microstructure can be used as the design of rare earth metal materials. The research and development and use of products provide reliable guarantee and basis. At the same time, it can also provide reference for the purchase and selection of materials. Therefore, the detection of physical properties of materials is very necessary.

The testing items

The physical properties of rare earth metals include magnetic properties, electrical properties, thermal properties, oxidation resistance, wear resistance, salt spray, corrosion, density, thermal expansion coefficient, elastic modulus, Young's modulus E and Poisson's ratio μ, hardness (Luo Hardness, Brinell hardness, Vickers hardness, Leeb hardness, Webster hardness, Knoop hardness).
