Standard GradeHeating Element
HE-NiCr80 Nickel-Chromium Resistance Wire
NiCr 80/20 resistance wire for general-purpose furnaces up to 1200 °C.
SAWHEAT's NiCr 80/20 resistance wire is drawn to tight dimensional tolerances and undergoes in-house resistivity testing to ensure batch-to-batch consistency. Supplied as wire, strip, or coiled element, it is the standard choice for chamber furnaces, conveyors, and industrial ovens operating continuously up to 1200 °C.
