Precision Alloy Rod
Product Details
Product Description:
Product Features
1J85 rod is a high-permeability soft magnetic alloy rod composed primarily of nickel and iron, known for its outstanding magnetic performance under low magnetic field conditions. This alloy exhibits excellent initial permeability, high saturation flux density, and low coercivity, making it ideal for precision magnetic components and shielding applications.
Technical Background
1J85 is a precision soft magnetic alloy containing approximately 80% nickel and 5% molybdenum. This material is heat-treated to achieve specific magnetic properties and maintain dimensional stability. The rod form is typically cold-drawn or ground finished to tight tolerances, ensuring uniform magnetic response throughout its length.
Applications
Magnetic shielding systems
Sensitive magnetic sensor cores
Transformer and choke cores
Recording heads
High-precision electromagnetic components in military and aerospace fields
Working Principle
The magnetic behavior of 1J85 rods is derived from its high nickel content and controlled grain structure, which allow magnetic domains to reorient easily under low applied magnetic fields. This results in minimal energy loss and high magnetic efficiency in AC and DC magnetic circuits.
