Cr20Ni35 nichrome nickel chromium spiral heating coil resistance wire
Resistance Alloy wire is used for electrical heating element.
Widely used in metallurgy, industrial stoves, household appliances, machinery and electronics manufacturing industries do heat resistance material.
1.FeCrAElectrictrical Resistance Heating alloys with high electrical resistivity, temperature coefficient of resistance is small, high operating
temperature. good corrosion resistance under high temperature, and particularly suitable for use in a gas containing sulfur and sulfides, low price,
it is widely used in industrial electric furnace, household appliances, far infrared device ideal heating material.
FeCrAl type:1Cr13AI4, 0Cr19AI2, 0Cr15AI5, 0Cr20AI5, 0Cr25AI5, 0Cr21AI6 Nb etc.Series electric flat belt, electric fire wire
2.Nickel chromium alloy with iron resistance electrothermal high resistivity, surface body sexual well. At high temperature and high intensity,
and a good performance and processing may welding nature widely used metallurgical, electrical, mechanical components and electrical
manufacturing industries for doing heat resistance material.
