Product Description

Description of 1j85 Soft Magnetic Alloy

SOFT MAGNETIC ALLOY TUBE

What is 1j85 Soft Magnetic Alloy?

He572b5d921ec495e8b163f8fefd1da8eN1J85 Soft Magnetic Alloy is a precision-engineered nickel-iron (Ni-Fe) based alloy renowned for its exceptional soft magnetic properties, including ultra-high saturation magnetic flux density and extremely low coercivity. This alloy maintains outstanding magnetic performance across a wide operational range, establishing itself as a fundamental material for high-efficiency transformers, sensitive sensors, and critical components in aerospace and telecommunications.

1j85 Soft Magnetic Alloy is particularly valued for its unparalleled combination of high permeability, minimal core loss, and excellent magnetic stability. Its excellent ductility and workability facilitate the fabrication of complex core shapes required in advanced electromagnetic designs.


SOFT MAGNETIC ALLOY TUBE

Characteristics of 1j85 Soft Magnetic Alloy

1. Ultra-High Saturation Flux Density

Enables the design of smaller, more powerful magnetic components with high efficiency due to its ability to handle strong magnetic fields. This is critical for miniaturization in advanced electronics and power devices.

2. Extremely Low Coercivity

Ensures easy magnetization and demagnetization with minimal energy loss, leading to high sensitivity and responsiveness in sensors and instruments. High permeability allows for efficient magnetic flux conduction.

3.Near-Zero Magnetostriction

Exhibits minimal dimensional change under magnetization, virtually eliminating vibration and audible noise ("hum") in transformers and inductors, essential for precision and quiet operation.

4.Good Ductility and Workability

Allows for relatively easy cold working and fabrication into complex shapes like thin strips, laminations, and precision cores required for sophisticated electromagnetic designs.
