1J79 Soft Magnetic Alloy Tubes: Precision Engineering for Electromagnetic Excellence

Product Overview

1J79, also known as Ni79Mo4 or Permalloy, is a high-performance soft magnetic alloy composed primarily of nickel (78.5–80%) and iron, with molybdenum (3.8–4.1%) as a key component. This alloy exhibits exceptional magnetic properties, making it ideal for applications requiring high magnetic permeability and low coercivity. The alloy's face-centered cubic (FCC) crystal structure contributes to its superior magnetic characteristics.​
