AWS D1.2 Basic Etchant, 250 mL
This formula is listed in AWS welding code D1.2/D1.2M annex as the “Basic Etchant”, and it’s recommended for macroetching aluminum weldments. The name “Basic” just means it’s not an acidic solution. We tested it on 3003, 5052, 5085, 5456, 6061, and 6063 aluminum welds, and it’s fast and effective as AWS suggested. Test results are here. Made with reagent grade chemical.
- Bring the sample surface to at least 600 grit finish before etching. Mirror polish the surface if possible. The finer the finish, the more details you will see.
- Apply to the area to be etched with cotton swabs.
- Heat the solution to 120°F/ 50°C will make it more effective.
- Shelf life is one year.
