High Performance Alloys
MPP Alloy (FeNi)
Empower precision applications with PML’s FeNi alloys, optimized for magnetic performance, corrosion resistance, and electrical efficiency.
Engineered for soft magnetic applications with superior ductility, high permeability, and minimal coercivity.
Ideal for transformers, sensors, magnetic shielding, and precision electronics-ready for advanced forming and machining.
Ingot Manufacturing Process
High-purity FeNi alloy ingots, made from virgin elements through controlled Air Induction Melting (AIM) technology.
RFQ from Customer
Alloy chemistry and ingot specifications are finalized as per application requirements.
Alloy Design/Planning
As per customer requirement mould design carried out and planned for charge preparation, charge sequences in Air induction melting furnaces in a controlled atmosphere.
Alloy Melting by AIM
Furnace cleaning, controlled charging, stirring, superheating, ceramic filtration, preheated moulds, and controlled cooling ensure high-quality, defect-free alloy ingots.
Process & Quality Control
The melt is prepared under Air induction melting furnaces in a controlled atmosphere. Argon gas purging from hood and bottom ensures to minimize gas impurities.
Primary Finishing
Post-casting processes include surface treatment, cropping, and preparation of ingots for downstream processing.
Testing & Packaging
Every batch is tested for chemical composition by Spark- OES / wet analysis / Gas analysis, and physical compliance as per customer specification before secure packaging.
