FeCrAl Alloy 815 Resistohm 135 Stablohm 812 0Cr23Al5 Heating Resistance Strips For Industry Resistor
0Cr23Al5 is a type of FeCrAl (Iron-Chromium-Aluminum) alloy strip commonly used in heating elements, electrical heating systems, and industrial furnaces. This specific alloy composition consists of 0% Nickel, 23% Chromium, and 5% Aluminum. The "0" in the name indicates the absence of Nickel in the alloy.
FeCrAl strips like 0Cr23Al5 are known for their high resistivity, excellent oxidation resistance at high temperatures, good mechanical properties, and long service life in demanding environments. They are often used in applications requiring high temperature stability and corrosion resistance, such as electric ovens, kilns, and heat treatment equipment.
