Where I can buy thick triangular sterling silver wire/rod?

I was wondering where I can buy thick triangular sterling silver wire/rod ?? (square & round also) 10mm x 10mm or so.
(or must one have the wire/rods cast ?)

I’m looking to try some file work like isaiah Ortiz’s piece’s (bracelet).

I have some casting, wire wrapping, soldering e.c.t experience. Tho I have little to no groove filing experience.

I’m gathering that the process is… (very roughly)… start with triangular shaped wire/rod, hammer & shape ends, heat & shape, mark & file. ???

Thanks :wink:

Good luck with your adventure, you can contact Indian Jewelry Supply for heavy wire, or since you have some casting experience make some wire using that technique
