ヘガネスジャパン

Recently, have you heard about "soft magnetic composites"? From the perspective of soft magnetic composites, we will gradually unravel 'Somaloy(R)'. 【What is Soft Magnetism?】 It refers to materials that are easily magnetized (high permeability) and have a low ability to retain magnetism (low coercivity). This includes various types and manufacturing methods such as electromagnetic steel sheets, soft ferrites, and powder magnetic cores. 'Somaloy(R)', which is based on pure iron, is classified as a powder magnetic core material. 【'Somaloy(R)' as a Soft Magnetic Composite】 - Manufacturing Method of Base Atomized Iron Powder By injecting high-pressure water into a molten bath (melted pure iron-based material) where the outflow is precisely controlled, the material is finely dispersed and rapidly cooled, solidifying into irregularly shaped iron powder with each particle having a different shape. - Towards Soft Magnetic Composites Each particle of this high-purity base powder is coated with an inorganic insulating layer several tens of nanometers thick, completing the soft magnetic composite 'Somaloy(R)'. → The next column will delve into its features and applications. *Keywords are high purity, irregular shape, and insulating coating. ★ Please download the information materials on 'Somaloy(R)' from the link below. ★ For requests or inquiries, please contact us at jumpei.ikeda@hoganas.com.
