[2025-10-01T03:08:13.624757] [PI reasoning] **Investigating soldering flux**

I need to look into the purpose of soldering flux, which is to remove oxide and promote wetting. I'm curious if fluoride flux is specifically used in dental soldering or metallurgy.

There are different types: For noble metals, we have borax flux, while fluoride flux works for base metal alloys like nickel-chromium and cobalt-chromium since borax doesn't work well with chromium oxide. Fluoride flux dissolves this chromium oxide, so its function seems to be preventing or dissolving that oxides layer. I'll check the literature for more information.
