Home > Permalloy Round Bar
Al Vishwas Nickel Alloys, headquartered in Dubai, UAE, is a premier manufacturer and supplier of high-performance specialty alloys designed for precision engineering and industrial applications. By placing strong focus on material innovation, advanced processing techniques, and strict quality controls, the company delivers reliable solutions for complex manufacturing requirements. Among its flagship products, the Permalloy Round Bar is celebrated for its exceptional magnetic characteristics, stability, and longevity. Produced under careful metallurgical control, these round bars are a preferred option for industries requiring high permeability and low coercivity, including electronics, instrumentation, sensors, and magnetic shielding.
Permalloy Round Bars are usually made up of roughly 80% nickel and 20% iron, along with carefully measured amounts of molybdenum or other elements depending on the particular grade. This distinctive makeup produces very high magnetic permeability, exceptionally low coercive force, and outstanding soft-magnetic properties. From a mechanical standpoint, Permalloy offers good ductility, moderate tensile strength, and stability even during repeated magnetic cycling. The alloy reliably provides dependable magnetic performance across a variety of temperatures and machines easily when it is in its annealed condition. Because of these attributes, Permalloy is an ideal option for applications demanding precise magnetic responses and minimal energy loss.
