Metallographic Etchants (Technical)

COMMON ETCHANTS

CAUTION:Safety is very important when etching. Be sure to wear the appropriate protective clothing and observe all WARNINGS on chemical manufacuters SDS (Safety Data Sheets). Also review the COMMENTS and CONDITIONS Section for each etchant.

Recommended Etchants

Aluminum alloys		High carbon steel

Brasses and Bronzes		Stainless steel

Cast Iron		Tin alloys

Copper alloys		Zinc alloys

Welding or Low carbon steels		Ceramics

Hastelloy and Nickel Superalloys

The following table lists the most commonly used etchants
