Home > Permalloy Round Bar
Santner Nickel Alloys, based in Hamilton, New Zealand, is a top-notch manufacturer and supplier of high-performance specialty alloys tailored for precision engineering and industrial uses. With a keen emphasis on material innovation, cutting-edge processing methods, and rigorous quality standards, the company provides dependable solutions for intricate manufacturing needs. One of its standout products, the Permalloy Round Bar, is renowned for its remarkable magnetic properties, stability, and durability. Crafted with careful metallurgical oversight, these round bars are a go-to choice for industries that demand high permeability and low coercivity, such as electronics, instrumentation, sensors, and magnetic shielding.
Typically, Permalloy Round Bars consist of about 80% nickel and 20% iron, with precise additions of molybdenum or other elements based on the specific grade. This unique composition results in very high magnetic permeability, extremely low coercive force, and excellent soft-magnetic characteristics. On the mechanical side, Permalloy boasts good ductility, moderate tensile strength, and stability even under repeated magnetic cycling. The alloy consistently delivers reliable magnetic performance across a range of temperatures and is easy to machine when in its annealed state. These qualities make Permalloy an excellent choice for applications that require precise magnetic responses and minimal energy loss.
