ZYTC Alloy is a professional Chinese manufacturer and supplier of high-performance 2J83, 2J84, 2J85 wrought iron-chromium-cobalt permanent magnet alloys. As mainstream deformable permanent magnet materials, Fe-Cr-Co alloys combine excellent ductility, reliable magnetic stability and superior machinability, occupying an irreplaceable position in precision magnetic component manufacturing.
Compared with traditional cast Al-Ni-Co alloys and Fe-Co-V permanent magnet alloys, 2J83/2J84/2J85 series materials deliver equivalent magnetic performance with more competitive cost advantages. Featuring uniform chemical composition, compact internal structure and stable comprehensive performance, these wrought magnet alloys can replace multiple conventional magnetic materials to produce complex-shaped precision magnetic parts. It is currently the most widely used flexible deformable permanent magnet alloy for industrial and high-precision instrumentation applications.
Chemical Composition (Typical wt%)
ZYTC Alloy strictly follows YB/T 5261 industry standards for smelting and composition control, ensuring consistent magnetic and mechanical properties across batches.
