Product Description
Magnetic Precision Alloys SUPRA 50 Series
SUPRA 50, 50T, 50SP, and SUPRA 510 foil alloys are nickel-iron soft magnetic materials containing 50% nickel. These precision alloys deliver exceptional magnetic performance for safety valves, resolvers, actuators, and other critical applications requiring reliable magnetic properties.
Key Characteristics
These FeNi 50 alloys excel in two primary application areas: energy conversion and information processing. In power applications, they provide high magnetic induction with low core loss under strong magnetic fields. For electronic applications, they offer high magnetic permeability and low coercive force at medium to low field strengths.
