Foam cutting help
I don't know of any professional foam cutters that still use nicrome wire. Stainless steel is better in every way. It is not as brittle. It is freer of kinks and bends. It can be used with higher tension. It is less expensive and easier to find. It lasts longer under heavy usage. It has a smaller temperature coefficient of expansion so that it is easier to maintain wire tension as the wire heats.
