Acid Etch Sheets Of Aluminum

I have been asked to take an 1 8 piece of aluminum and etch away much of it for an art piece.

Acid etch sheets of aluminum.

Depending on the aluminum grade and the acid type acidic solutions can sometimes remove other substances from aluminum machine parts without damaging the metal. The solution is 80 ml of orthophosphoric acid 10 ml of nitric acid 10 ml of acetic acid and 20 ml of water. My last and only experience with acid etching was in a school environment more than a decade ago. There is an etch commonly used in the microelectronics industry for etching aluminium.

By selectively using acid to burn away parts of a piece of metal you can create spectacular works of art. Different aluminum grades react differently to chemicals such as acids. Safe acid etching of aluminum. The solution works best when heated to about 60 c.

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. But one of the best parts about the process is that it can be used in a variety of different styles. A discussion started in 2002 but continuing through 2017. 1k ready to spray phosphoric acid ester formula promotes paint adhesion to difficult substrates like galvanized steel and aluminum.

Certain acid types will not harm some aluminum grades while other acid types will.
