Iron-chromium-aluminum Resistance heating wire and strip FeCrAl alloys are available as wire, strip, welded and seamless tubes; All these product forms are available from stock for fast deliveries. The high aluminum content, in combination with the high chromium content causes the scaling temperature to increase up to 1425 C (2600F ); Under the headline heat resistance, these FeCrAl alloys are compared with commonly used Fe and Ni base alloys. As can be seen from that table, the FeCrAl alloys have superior properties as compared to the other alloys.
FeCrAl alloys are widely used in industrial electrical furnace, electrical oven, home appliance, electrical heator, infrared settings, etc.
Max continuous working temperature: 1250 C.
Melting Temperature: 1500 C
Electric Resistivity: 1.42 ohm mm2/m
Diameter: 0.01mm-10mm
Iron-Chromium-Aluminum FeCrAl alloys has been used extensively as heating elements in industrial furnaces and electrical kilns and has less hot strength than Tophet alloys but much higher melting point.
FeCrAl alloys Main Applications
Our high resistance electric heating alloy has a wide range of temperatures. The highest temperature can reach 1, 400° C. Besides, we have eleven different kinds of alloys, each type has its own temperature range and resistivity. So our products have various applications.
Over a long period of time, our products (Fe-Cr-Al/Ni-Cr) high resistance and heating alloy materials are salable and widely used in various industries, such as metallurgical, chemical, glass, ceramic, and electrics for instance, they can be used for industrial and civil heating-furnace, infrared equipment, liquefied gas infrared heat-resisting net, different kinds of igniting and radiating electrodes and voltage-regulating resistors for motors and so on.
Meanwhile our products are ideal materials for heating elements of electric stove, electric teapot, electric iron, electric blower, soldering-iron, electric water heater and indoor air-conditioner and etc.
