Why Choose Professional 1J85 & 1J50 Permalloy for Your Precision Projects? In the fast-growing fields of new energy vehicles, quantum computing, 5G/6G communications, aerospace, and medical MRI equipment, soft magnetic alloys directly determine product accuracy, energy efficiency, and stability. Choosing the wrong material leads to high losses, poor shielding, and unstable mass production. Choosing the […]

Alternative Names: 1J85 (Ni80Mo5, Supermalloy, 79HMA, E11c); 1J50 (50NiFe, Hy-Ra49, Radiometal, 50H Permalloy) In the realm of soft magnetic materials, Permalloy stands as a cornerstone—renowned for its exceptional magnetic permeability, low coercivity, and versatile performance. Among the most widely specified grades, 1J85 and 1J50 dominate high-precision electronics, industrial automation, and advanced manufacturing. While both belong to the

Also known as: 1J85 (Ni80Mo5, 79HMA, E11c, PCS, Supermalloy); 1J50 (50NiFe, Hy-Ra49, Radiometal, 50H Permalloy) Introduction Permalloy (nickel-iron soft magnetic alloys) are foundational materials in modern electronics, power systems, and precision engineering. Among them, 1J85 and 1J50 stand out as two of the most widely used grades—each optimized for distinct performance needs: 1J85 for ultra-high

Also known as: Invar, NILO 36, 1.3912, 4J36, Nickel-Iron 36 Alloy 1. What is Invar 36 Alloy? Invar 36 is a 36% nickel-iron precision alloy renowned for its near-zero coefficient of thermal expansion (CTE). Discovered by Swiss physicist Charles Édouard Guillaume in 1896 (who won the 1920 Nobel Prize in Physics for this breakthrough), Invar
