Wai Nickel Alloys, a prominent manufacturer and supplier located in Naypyidaw, Myanmar, specializes in high-quality Permalloy Foil, renowned for its exceptional magnetic permeability and low coercivity. Made from a Nickel-Iron alloy, this foil excels in electromagnetic and shielding applications. Each piece of Permalloy Foil is meticulously crafted to ensure uniform thickness, flexibility, and robust mechanical integrity. Its outstanding magnetic characteristics make it perfect for reducing energy losses in delicate electrical systems. With a commitment to quality, durability, and performance, Wai Nickel Alloys’ Permalloy Foil efficiently supports industries like electronics, telecommunications, and instrumentation.
Permalloy Foil is generally made up of 80% Nickel and 20% Iron, providing remarkable magnetic permeability and low coercivity. It has a density of around 8.7 g/cm³, with tensile strength between 400–600 MPa, while also maintaining excellent ductility and formability. The alloy shows minimal magnetostriction and high electrical resistivity, which helps to cut down on eddy current losses in alternating magnetic fields. Even under repeated magnetic cycling, Permalloy Foil keeps its magnetic and mechanical properties stable, making it perfect for applications that need precise control of magnetic flux and effective electromagnetic shielding.
