Nickel Chromium Alloy Nichrome Wire (Ni80Cr20)
Nichrome is an alloy of nickel and chromium (80% Ni, 20% Cr) and can withstand a high temperature up to 1200 °C. Moreover, it possesses good resistance to oxidation, good electric resistance and high-temperature capability. The nichrome series contains an alloy of nickel and chromium, mainly 80% Ni-20% Cr, 60% Ni-16% Cr, and 35% Ni-20% Cr.
Princeton Powder is a leading supplier of high purity nichrome (Ni–Cr 80/20 wt.%) film, wire, pellet, and Evaporation Materials in the United States.
