Attention those struggling with magnetic properties! We are offering an FAQ document about the soft magnetic material "Permalloy," which has low coercivity and high permeability! A list of thicknesses is also included.
Permalloy is a nickel-iron alloy that contains 35-80% nickel (Ni) and is supplied in various forms such as sheets and rods, similar to many other metals. Its appearance is not significantly different from stainless steel or iron, but it possesses special properties that strongly attract magnetism. Due to its low coercivity and high permeability, it has a high magnetic shielding effect and a strong magnetic collecting action. It also exhibits a large output (magnetization) in response to fine input (magnetic field), and it increases the resistance (the ratio of voltage to current) in alternating current. As a result, it is applied in magnetic shielding rooms, magnetic shielding cases, magnetic shielding boxes, magnetic sensors, and various inductors (coils with windings on a core). It is effective in a relatively low frequency range, from extremely low frequencies below 1 Hz to commercial frequencies up to 200 Hz. 【Effects】 ■ High magnetic shielding effect and strong magnetic collecting action ■ Large output (magnetization) in response to fine input (magnetic field) ■ Increases resistance (the ratio of voltage to current) in alternating current *For inquiries or consultations regarding Permalloy, please use the contact form on our company website. 【Contact】https://www.ohtama.co.jp/contact.html
