High Permeability Soft Magnetic Alloy

Permalloy 80 is a type of alloy that is made up of nickel, iron, and molybdenum. It is a highly magnetic material that is commonly used as a magnetic core material in electrical and electronic equipment. This particular alloy has a composition of approximately 80% nickel, 15% iron, and 5% molybdenum. Compared to ordinary steel, commercial permalloy alloys have a relative permeability of around 100,000. This means that it provides maximum magnetic permeabilities and minimal core losses at low field strengths.

One of the most significant advantages of permalloy 80 is its small size and weight. This makes it an ideal material for use in magnetic core and shielding applications where space is limited. Additionally, this vacuum-melted product has near-zero magnetostriction and significant anisotropic magnetoresistance.

Permalloy 80 offers high initial and maximum permeabilities with low coercive force, low hysteresis loss, low eddy-current losses, and low magnetostriction. These properties are critical for industrial applications, especially in thin films where variable stresses would otherwise cause a large destructive variation in magnetic properties.

Overall, permalloy 80 is a versatile and reliable material that finds wide application in the electrical and electronic industries. Its unique magnetic properties make it an essential component in many applications where precise control of magnetic fields is required. It is particularly useful in situations where space is at a premium, as its small size and weight allow it to be used in tight spaces without sacrificing performance. Its low coercive force, hysteresis loss, eddy-current losses, and magnetostriction make it an ideal material for use in thin films where variable stresses can cause significant variations in magnetic properties. In short, permalloy 80 is a high-performance material that is an excellent choice for many industrial applications.
