Nichrome Ni60Cr15 resistance wire for Air heaters
(Common Name:Ni60Cr15,Chromel C, Nikrothal 60, N6, HAI-NiCr 60, Tophet C, Resistohm 60, Cronifer II,Electroloy, Nichrome, Alloy C, Alloy 675,Nikrothal 6, MWS-675, Stablohm 675,NiCrC)
Ni60Cr15 is a nickel-chromium alloy (NiCr alloy) characterized by high resistivity, good oxidation resistance ,good form stability and good ductility and excellent weldability. It is suitable for use at temperatures up to 1150°C.
Typical applications for Ni60Cr15 are used in metal sheathed tubular elements,for example,hot plates,
grills,toaster ovens and storage heaters.The alloys is also used for suspended coils in air heaters in clothes dryers,fan heaters,hand dryers etc.
