High Permeability Soft Magnetic Alloy
Permalloy 80 is a type of alloy that is composed of a mixture of nickel, iron, and molybdenum. This alloy is particularly noteworthy for its soft magnetic properties and its exceptionally high magnetic permeability. Additionally, Permalloy 80 has a low coercivity, which means that it requires very little energy to change its magnetization.
One of the most significant benefits of Permalloy 80 is its near-zero magnetostriction. Magnetostriction is a phenomenon where a material changes shape when it is magnetized. In many cases, this can cause significant problems for industrial applications, particularly when thin films are involved. However, because Permalloy 80 has such a low magnetostriction, it is much less susceptible to changes in shape when it is magnetized.
Another important property of Permalloy 80 is its anisotropic magnetoresistance. This refers to the fact that the electrical resistance of the material changes depending on the direction of the magnetic field that is applied to it. This property makes Permalloy 80 particularly useful in applications where it is important to be able to measure magnetic fields accurately.
Overall, Permalloy 80 is an incredibly useful material for a wide range of industrial applications. Its soft magnetic properties, high magnetic permeability, low coercivity, and low magnetostriction make it an ideal choice for applications where precise control over magnetic properties is essential.
High sensitivity and small power transformers, magnetic amplifiers, relays, chokes, magnetic heads for magnetic recording devices, magnetic shields, various tape wound cores, cut cores, and laminated cores used in weak magnetic fields.
