Home > Permalloy Round Bar
Wai Nickel Alloys, a prominent manufacturer and supplier located in Naypyidaw, Myanmar, specializes in high-quality Permalloy Round Bars that are celebrated for their outstanding magnetic properties and mechanical strength. Crafted from a top-notch Nickel-Iron alloy, these bars boast high magnetic permeability and low coercivity, making them perfect for precision magnetic and electrical applications. Engineered for reliable performance, excellent machinability, and precise dimensions, Permalloy Round Bars maintain stable magnetic properties even under varying conditions. This makes them ideal for sensitive electrical components, shielding systems, and electromagnetic equipment, all while meeting the rigorous demands of modern industrial applications.
Permalloy Round Bars primarily consist of Nickel (about 80%) and Iron (around 20%), with small amounts of elements like Molybdenum or Copper added to enhance specific magnetic traits. They are known for their high magnetic permeability, low coercive force, and minimal magnetostriction, which ensures top-notch magnetic performance. On the mechanical side, they offer tensile strength ranging from 400 to 600 MPa, a density of 8.7 g/cm³, and remarkable ductility and machinability. The alloy’s high resistivity helps reduce eddy current losses, making it perfect for alternating magnetic fields while ensuring stability and reliability under cyclic magnetic conditions.
