Soft Magnetic Alloys
High-permeability soft magnetic alloy with excellent EMI shielding and corrosion resistance for advanced electronic and power applications.
By combining 80% nickel with specialized iron purity, this alloy provides an exceptional barrier against stray magnetic fields in high-precision medical and aerospace electronics.
Ni80Fe20 ingots are produced using Vacuum Induction Melting (VIM) to ensure precise composition, purity, and superior soft magnetic performance.
Ni80Fe20 ingots are produced using Vacuum Induction Melting (VIM) to ensure precise composition, purity, and superior soft magnetic performance.
As per customer requirements, mould design carried out and planned for charge preparation, charge sequences in VIM furnace. Careful selection of raw materials are the prime factor to achieve specified chemistry of an alloy.
Virgin elements are charged into the VIM furnace either in air or under vacuum, with precise adjustments made for trace element additions during melting.
The melt is poured under vacuum into precision-engineered molds using an automatic tilting mechanism for defect-free solidification.
Each ingot undergoes full PMI verification and chemical analysis prior to dispatch for applications like MIM powders, hot/cold rolled strips, or forged components.
Each ingot undergoes rigorous inspection, precision processing, and custom packaging according to the requirements.
