Project Description

Nichrome 80 (UNS N06003/2.4869)

Nichrome 80 (UNS N06003/2.4869) is a nickel-chromium resistance alloy for operating temperatures up to 1200℃. It has highly corrosion resistance and lower coefficient of resistance than other heater element alloys. Nichrome 80 is the most ideal resistance heating alloy.
