High Permeability Soft Magnetic Alloy

Manufacturer Supply Special Precision Nickel Alloy Super Permalloy Wire

1J77 is a type of magnetic alloy that is composed of approximately 80% nickel and 20% iron. It was invented in 1914 by physicist Gustav Elmen at Bell Telephone Laboratories, and is known for its exceptional magnetic permeability. This property makes it highly useful in electrical and electronic equipment as a magnetic core material, as well as in magnetic shielding to block magnetic fields.

Compared to ordinary steel, commercial permalloy alloys have a relative permeability of around 100,000. In addition to its high permeability, 1J77 also possesses other desirable magnetic properties such as low coercivity, near-zero magnetostriction, and significant anisotropic magnetoresistance. Its low magnetostriction is especially critical in industrial applications, as it allows the alloy to be used in thin films without experiencing variable stresses that would otherwise negatively impact its magnetic properties.

However, one disadvantage of 1J77 is that it is not very ductile or workable, which limits its use in applications that require complex shapes. In such cases, other high-permeability alloys such as mu metal are used instead. Despite this limitation, 1J77 is still widely used in various industries including radio-electronics, precision instruments, remote control systems, and automatic control systems.

Overall, 1J77 is a highly versatile and valuable magnetic alloy that has played a crucial role in the development of modern technology. Its unique properties make it an essential component in many electronic devices and systems, and its continued use is expected to drive further advancements in the field of electrical engineering.

Applications

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.
