An odd and suspiciously cheap 100g roll of solder on AliExpress, that I decided to test.
The alloy isn’t indicated, but it is flux cored, with quite an aggressive flux.

The Chinese text on the reel actually says "stainless steel solder" and it does actually work on stainless. Not sure how strong it would be though.

The reel it comes on also has a special feature….

Here’s the listing it came from, but I don’t really recommend it:-

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- https://www.bigclive.com/coffee.htm
This also keeps the channel independent of YouTube’s algorithm quirks, allowing it to be a bit more dangerous and naughty.
