Etch at 3 – 6 volts for 5 – 60 seconds . A good general etchant for revealing the microstructure of base metals and welds. WebEtches cleanly with only a deionized water rinse needed. Chromium etchant is a chromium based solution that removes the excess metal from the substrate. These etchants are majorly used in metal finishing and electronic industry. It has an etch rate of 4 mm/s and can be used to etch nickel, copper, and chromium based excess metals.
