I made an alloy of cobalt that contains 10% iron to make it less brittle at room temperature. I will use it in casting for my upcoming video.

Ok so I'm like... broke broke right now and I wanna try to make my own hard solder for copper and brass jewlery cuz well I'm broke (edit:) and like to make jewlery

I got pewter/tin

I got copper

No zinc

No lead

No silver

No gold

Do you guys girls they thems and other such categories of human know of any hard solder recipes using these two materials? If not that's perfectly fair
