CoVFeFe
Iron Cobalt Vanadium Alloy
soft magnetic alloy with the highest flux density of any strip core alloy, making it ideal for use in tape cores and magnetic cores in electrical equipment
Wonder if Tesla ever used this alloy.
Cras es noster.
>Just for kicks, I checked archive.org to see when CoVFeFe started showing up as an alias for Iron Cobalt Vanadium Alloy on AmericanElements.com - earliest snapshot showing CoVFeFe is 6/17/17, after the famous POTUS tweet, so it was probably just Chemist humor.
