hey guys, I'm Mason, I'm new here. A friend and I are going to try some pattern welding and are planning on trying to do it with copper and aluminum because they are both pretty easy for us to get, and have low melting points. We're probably gonna try and make some rings or something, not quite sure yet. Right now the plan is to take an aluminum rod and wrap it in copper wire then heat that. Aluminum has the lower melting point of the two, so having it in the core in rod form and having the copper on the outside in wire form will help them initially melt at similar times (hopefully).
does anyone have any advice? do you know if this will work or not? I haven't heard of anyone trying this, so I'm taking that as a bad sign. If you have tried this, what's the best acid to use to etch it?
