We’re aware that there is some confusion about this wire. We have been informed that many of you refer to this wire based on the FeCrAl content and not the Nickel content.
We require total consistency and we use the Nickel content as the main descriptor for our products.
This wire is NiFe52 because it has approx 52% Nickel content. We do this to keep consistency with the other Nickel wires – Ni80 = 80% Nickel, Ni60 = 60% Nickel, NiFe70 = 70 Nickel etc.
We apologise if this is at odds with how others refer to this wire, but we’re sure that you can see why this is the case.
