Aluminum Sheet for jewelry making: 6x6" (approx. 150x150 mm) sheets of anodized aluminum sheet is easy to metal stamp, and can easily be cut with shears, or used with punches to create shapes. Sizzix and Vintaj DecoEmboss and DecoEtch dies work great with this 24-gauge soft aluminum! Add holes with a drill press, or use hole punch pliers or your favorite hole punch tools.
Aluminum does not rust, nor does it take a patina with the standard chemicals normally used to oxidize (darken) jewelry. It oxidizes as soon as it comes into contact with oxygen or water! Fortunately this oxidized layer of aluminum oxide (Al2O3) immediately forms a stable layer that protects aluminum from corrosion or further oxidation (as long as it isn't exposed to chlorine or similar corrosive substances). Do not use Win-Ox™ on aluminum.
