Chemical Etching with Nickel Silver

Nickel silver shares many of the same characteristics as copper in terms of electrical and thermal conductivity, but is stronger and more durable. Engineers can rely on it for its resistance to corrosion and fine grain to use it in many manufacturing processes. 

E-Fab’s nickel silver manufacturing experience includes producing shields and MRI materials for companies in the electronics and microwave industries. 

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