Nichrome Cr15Ni60 chrome nickel wire high temperature resistance alloy wire resistance
The Cr15Ni60 resistance alloy is composed of nickel-chromium alloy, which has high resistivity, good oxidation resistance and very stability. The maximum applicable temperature is up to 1200 degrees, and it has a longer service life than iron, chromium and aluminum.The alloy is widely used in household components, industrial furnaces and various resistance components, such as wirewound resistors, sheet metal resistors, hair dryers, electric furnaces, iron smelting, ovens, and even electronic cigarettes.
