Iron Chrome Aluminum FeCrAl Alloy 0Cr23Al5 7.25 Density For Air Dry
Heater
Resistance Heating Alloy Wires is used for electrical heating element. Xingtai produced
high-resistance electrothermal alloy products for the high-purity,
low impurity resistivity stability, temperature coefficient small,
superficial body Sexual good, and the higher intensity and high
temperature performance and good processing may welding nature
steels varieties specifications complete. Widely used in
metallurgy, industrial stoves, household appliances, machinery and
electronics manufacturing industries do heat resistance material.
FeCrAl Electrictrical 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.
