Aurico Alloys LLP, medical grade Elgiloy foil supplier in Mumbai, stocks affordable, authentic UNS R30003 foil from India to abroad for chemical, oil & gas, marine, pharma, power, hardware—ISO 5832-7 biocompatible with EN 10204 3.1 MTC.
Elgiloy foil (Phynox equivalent, Co-Cr-Ni-Mo alloy) outperforms MP35N/stainless in high-cycle fatigue (10x cycles), corrosion (17% better than SS), and non-magnetic stability ideal for stents where alternatives embrittle. With modulus 190 GPa, it stores 20% more elastic energy, enabling smaller medical devices.
As ASTM F1058 Elgiloy shim stock manufacturer in Mumbai, we offer custom slit-to-width rolls for stamping, supporting fabricators with Elgiloy foil price per kg in India for dental wires and aerospace. Elgiloy vs Phynox shines in high-temp springs.
