Soft Magnetic Alloy Wire
Your Trusted Source for Precision Alloy Manufacturing
Soft magnetic materials are alloys with high magnetic permeability, low coercivity, and minimal energy loss during magnetization and demagnetization cycles. These properties make them ideal for applications involving alternating or fluctuating magnetic fields, such as transformers, motors, and inductors.
