Product Details

China chrome heater strip product OCr21Al6Nb

Resistance Alloy strip 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, 0Cr21AI4, 0Cr21AI6, 0Cr25AI5, 0Cr21AI6 Nb, 0Cr27AI7Mo2 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.
