Rare Earth alloys
FeLaSi Alloy
Depend on PML’s FeLaSi alloy for advanced magnetic performance, catalytic properties, and high-temperature resilience.
Engineered for strength, magnetic stability, and wear resistance-thanks to silicon and lanthanum microalloying.
Ideal for magnetic components, catalytic converters, and high-temperature aerospace or automotive applications.
High-purity FeLaSi alloy ingots, crafted from virgin elements through Vacuum Induction Melting (VIM).
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 VIM furnace. Careful selection of raw materials are the prime factor to achieve specified chemistry of an alloy.
Alloy Melting by VIM
Virgin elements are charged into the VIM furnace either in air or under vacuum, with precise adjustments made for trace element additions during melting.
Process & Quality Control
The melt is poured under vacuum into precision-engineered molds using an automatic tilting mechanism for defect-free solidification.
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.
