Why Hiperco27 Alloy Powder Is the Ideal Choice for High Magnetic Saturation Applications

Published by HUAXIAO TECH manufacturer

In critical fields such as aerospace, electric motors, and precision instruments, materials with ultra-high magnetic saturation and low core losses are essential. Hiperco27 alloy powder stands out for its outstanding soft magnetic performance, particularly in demanding electromagnetic environments.

Unique Composition for Maximum Magnetic Performance

Hiperco27 is an iron–cobalt soft magnetic alloy containing approximately 27% cobalt and a balance of iron with trace elements for grain refinement. Its key features include:

• Very high magnetic saturation (~2.35 Tesla)

• Excellent permeability at moderate fields

• Stable mechanical and magnetic properties at elevated temperatures

This composition ensures high efficiency in electromagnetic conversion and field control systems.
