I create hand stamped jewelry and the main metal I use is aluminum. We just purchased a tumbler from HF and I do not want to ruin a batch of my blanks by not tumbling them correctly. Can you please help me and advise me on what solution to use on the disks to get them shinny? I have heard not to use steel shot on them, but am still confused as to what to use.
The tumbling needs for aluminum are different than those of say copper or Sterling silver. I personally do not work with or use aluminum for jewelry making. So, I'm sending you to a link of a Lizz Barnes who uses aluminum a lot.(just copy and paste in your browser window)
With aluminum being so soft, what Lizz says about using only round stainless steel shot - no pins - makes sense. I know that aluminum is especially sensitive to salts and chemicals commonly found in water as it pits easily. Distilled water might be a good idea as it has had all chemicals and minerals removed.
I hope you find the information on Lizz's site helpful and have success in achieving a high polish finish on your aluminum pieces!
