This comprehensive guide explores our capabilities as a FeNi50 supplier, the unique properties of this alloy, and its wide-ranging applications across high-tech sectors.
Understanding FeNi50 Alloy Composition and Properties
FeNi50, also known as 50Ni-50Fe or Permalloy, is a nickel-iron soft magnetic alloy containing approximately 50% nickel and 50% iron. This precise composition gives the alloy its remarkable magnetic properties, including high magnetic permeability and low coercivity, making it ideal for applications requiring efficient magnetic field manipulation.
Our manufacturing process ensures the highest purity levels, with strict control over trace elements that could affect performance. The alloy’s unique microstructure, achieved through specialized heat treatment, provides excellent stability across a wide temperature range (-60°C to +200°C) while maintaining consistent magnetic characteristics.
Key Properties of FeNi50 Alloy:
- High initial permeability (up to 100,000)
- Low coercive force (<0.8 A/m)
- High saturation magnetic flux density (1.5-1.6 T)
- Excellent corrosion resistance
- Good thermal stability
- Low magnetostriction coefficient
- High electrical resistivity
