Nichrome wires are also hot wires.
The cutting wires for the cutting machine are nichrome wires cr20ni80 which can be heated by the electricity,it can melt and cut the expanded polystyrene foam with high temprature. NiChrome Wire (NiCr) is also called hot wire in eps industry.It is good performance in working as cutting foam. it is resistant to corrosion and oxidation,and it can reach high temperature in just seconds.The NiChrome wires can be with high tensile strength and high melting points.It has perfect balance between energy requirement and good tensile strength.
