Frequently Asked Questions

What types of Invar alloys are suitable for etching?

Invar is available in different alloy compositions with varying levels of nickel and iron. For example, Invar 36 is commonly used for etching due to its stability and properties. Connect with our team to learn more about which Invar alloy is best suited for your project. 

What is the average turnaround time for Invar etching projects? 

The etching rate is controlled by operators based on the process an expert team of engineers has developed for each part of your project. Generally speaking, the deeper the etches and the thicker the material, the slower the etching rate. If you’re seeking a quick turnaround time, it may be beneficial to choose a thinner material with a less complex design.

Connect with our team to learn more about the specific etch rate for your project based on your specifications.  

Are there design considerations for Invar etching?

Fortunately, photochemical etching does not affect the material’s properties. Learn more about how Elcon Precision can handle your design specifications via our Invar etching process developed over the last 60 years.
