Do you have to use a high flame to ball up copper wire? Can nickel
wire be used for rivets? Can nickel be balled up?
you can do anything if you have a go.
Just try it!!.
Try and be more precise. Do you mean pure nickel? Id be very
surprised if youve got you hands on some.
Nickle brass rivets can be bought from model engineers suppliers.
Metals that your torch will melt can be balled up, but to prevent
oxidation you need to flux the wire end. Try it and report back how
you got on.
