Acid Etch Sheets Of Aluminum

There is an etch commonly used in the microelectronics industry for etching aluminium.

Acid etch sheets of aluminum.

Different aluminum grades react differently to chemicals such as acids. But one of the best parts about the process is that it can be used in a variety of different styles. The solution is 80 ml of orthophosphoric acid 10 ml of nitric acid 10 ml of acetic acid and 20 ml of water. I have been asked to take an 1 8 piece of aluminum and etch away much of it for an art piece.

Ideal for rub throughs in primer prior to application of color and on new bare metal panels. The solution works best when heated to about 60 c. Safe acid etching of aluminum. By selectively using acid to burn away parts of a piece of metal you can create spectacular works of art.

List of materials some aluminum panel s a nice design for the etching laser printer w black ink some pnp blue sheets gloves eye protection glasses protective clothing hydrochloric acid same thing as as muriatic acid hydrogen peroxide same thing as oxygenated water a shallow plastic container to mix the peroxide with the acid 2 1 mix depending on the peroxide concentration you may need. Etch and prime bare metal in one step creates an anti corrosive barrier that prevents steel from rusting can be directly topcoated no sanding required available in. Certain acid types will not harm some aluminum grades while other acid types will.
