Home > Permalloy Round Bar
Barsham Nickel Alloys, Doha, Qatar, is a reputable producer and distributor of premium nickel alloys and special metals. We deliver secure, lasting solutions to the aerospace, oil and gas, and electronics industries. Our Permalloy Round Bars are designed with superior magnetic properties, so they’re perfect for applications that demand high permeability and low coercivity. These bars possess outstanding corrosion resistance and find extensive application in transformers, electrical devices, and magnetic shielding. We provide timely delivery with all our customers’ specifications obtained with precision and efficiency.
Permalloy Round Bars consist mainly of 80% nickel and 20% iron, with traces of molybdenum and copper added to improve magnetic properties. This composition provides the material with outstanding magnetic permeability and low coercivity, suitable for electromagnetic uses. The mechanical properties are tensile strength of around 60-70 ksi (415-485 MPa) and yield strength of 35-45 ksi (240-310 MPa). The density is approximately 8.7 g/cm³, and the material melts at about 1,400°C (2,552°F). These bars offer superior performance in high-precision, magnetically sensitive applications.
