0Cr27Al7Mo2 is an iron-chromium-aluminium alloy (FeCrAl alloy) for use at temperatures up to 1400°C (2552°F). The alloy with the characteristics of high resistivity, low temperature coefficient of electric resistance, high operating temperature, good oxidation resistance under high temperature. It can equal to APM.
In the industrial field, electric furnaces are widely used in various heating processes, such as metal heating, glass manufacturing, ceramic sintering, etc. 0Cr27Al7Mo2 resistance wire, as the heating element of electric furnaces, can operate stably in high-temperature environments, providing the required heating power to efficiently heat the workpiece.
Resistance heaters are a common type of heating device that uses the heat generated by passing current through resistance wire to heat the workpiece. 0Cr27Al7Mo2 resistance wire is commonly used as the heating element of resistance heaters due to its excellent resistance characteristics and high temperature resistance, and it can be widely used in industrial heating, laboratory research, and other fields.
Electric heating tubes are devices that use the heat generated by resistance wire to heat fluids or gases. 0Cr27Al7Mo2 resistance wire is made into the heating core of electric heating tubes, providing stable heating effects and widely used in household and industrial equipment such as electric water heaters and electric fans.
Electric heating is a common heating method in the process of metal smelting. 0Cr27Al7Mo2 resistance wire is used as the electric heating element of melting furnaces, providing high-temperature and high-power heating effects to efficiently carry out metal smelting.
