High-Permeability 1J85 Soft Magnetic Alloy Pipes for Precision Electronics
Product Overview
1J85, also known as Ni80Mo5 or Supermalloy, is a high-performance soft magnetic alloy composed primarily of 79.0–81.0% nickel and 4.8–5.2% molybdenum, with iron as the balance. This alloy is renowned for its exceptional magnetic properties, including high initial permeability and low coercivity, making it ideal for applications requiring efficient magnetic flux control in weak magnetic fields.
The alloy's high nickel content imparts excellent magnetic permeability, while the addition of molybdenum enhances its resistance to magnetic aging, ensuring long-term stability of magnetic properties. The low coercivity characteristic allows for easy magnetization and demagnetization, which is crucial in reducing energy losses in electromagnetic components.
1J85's physical properties include a density of 8.75 g/cm³ and an electrical resistivity of 0.56 μΩ·m. The Curie point, which is the temperature above which the material loses its permanent magnetic properties, is approximately 400°C. These attributes contribute to the alloy's suitability in high-frequency applications where thermal stability and minimal energy loss are essential.
