Compared with the conventional Cr20Ni80 electric heating alloy，ultra-pure Cr20Ni80 alloy wire can draw fine wires less than Φ1mm，The purity of the alloy is much higher than the conventional Cr20Ni80，The product strength is slightly reduced，but the plasticity is improved a lot，and it can be wide Hot working within the temperature range。
