Product Description
High Resistance AISI Nichrome Ni70Cr30 Nickel Alloy Wire For Laboratory Equipment
Ni70Cr30 Heating Resistance Wire
Ni70Cr30 is an austenitic nickel-chromium alloy suitable for temperature applications up to 1250°C. High chromium content (30% in average) provides very good life time, especially in furnace applications.
Ni70Cr30 is characterized by high resistivity, good oxidation resistance, good ductility after use and excellent weldability. Alloy is not subject to "green rot" and is particularly well suited for reducing and oxidizing atmospheres.
