Performance Characteristics of Transverse Magnetic Cores

Iron-based nanocrystalline cores heat-treated by transverse magnetization have a high saturation magnetic induction of 1.25 T (relative to ferrite), high permeability u=30,000-100,000 (relative to ferrite u=10,000 or less), low remanent magnetization Br value, typically a rectangular ratio of Br/Bm<0.3 (relative to iron nanocrystalline cores without transverse magnetization heat treatment Br/Bm>0.6), and low iron loss (relative to ferrite, iron nanocrystalline cores without transverse magnetization heat treatment, conventional silicon steel sheet materials). cores Br/Bm>0.6), low iron loss (relative to ferrite, iron-based nanocrystalline cores without transverse magnetization heat treatment, and conventional silicon steel sheet materials). Iron-based nanocrystals heat-treated by transverse magnetization have low remanent magnetization Br because of the high saturation magnetic induction Bs

Magnetic materials industry faces consolidation

At present, compared with the international advanced level, China's magnetic materials industry is at a disadvantage. In the fierce international competition, the domestic magnetic materials industry will surely grow out of the international magnetic material giants, and even the international electronic component giants. We expect that the growth of international giants from national magnetic material enterprises will go through the following stages. 　   Concentration strategy Starting from scratch and growing from small to large is generally suitable for the adoption of a concentration strategy. From the viewpoint of the international life cycle of a product, the product is generally in the period of expanding to the market of a developing country, and the means of competition has generally reached the stage of relying mainly on cost leadership to gain an advantage.

Process properties of metallic materials

Metal on a variety of machining process methods shown by the adaptability known as process performance, mainly in the following four areas: (1) cutting performance: reflecting the use of cutting tools (such as car).
