Super Alloys
High-strength nickel alloy for high-temperature structural applications


Designed for service temperatures up to 815°C, Nimonic 80A combines high tensile strength, creep resistance, and oxidation stability.
Manufactured from virgin raw materials using Vacuum Induction Melting (VIM) technology to ensure controlled chemistry and minimal impurities.
Alloy chemistry and ingot specifications are finalized as per application requirements.
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.
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.
Post-casting processes include surface treatment, cropping, and preparation of ingots for downstream processing.
Every batch is tested for chemical composition by Spark- OES / wet analysis / Gas analysis, and physical compliance as per customer specification before secure packaging.
