Jun 26, 2003 #1 Bobchan Mechanical Jun 26, 2003 1 HK Hello, I'm having problems etching an Aluminum 2000 & 3000 series. I've tried the Keller's and 10% phosphoric acid, but none have worked so far. My objective is to see the grains by a digital mircoscope. Do you have any other suggestions I could try?
