Chemical Etching with Nickel Iron

When it comes time to look for a versatile, strong, and corrosion-resistant metal, many engineers and manufacturers turn to nickel iron. Nickel iron is a versatile material ready for forming, plating, can laser welding for hermetic sealing.

E-Fab uses nickel iron to expertly produce transformers, inductors, magnetic amplifiers and shields, covers, carriers, and contacts. We have a decades-long track record of supplying clients in the electronics and microwave industries with our precision nickel iron parts.

We welcome your questions about how to use nickel iron for your parts.
