Product Detail

Model No.: FCA1010
Packing: as the buyers' option

Fe-Cr-Al (Iron-Chromium-Aluminum) alloys are available as wire, strip, welded and seamless tubes; All these product forms are available from stock.

Fe-Cr-Al (Iron-Chromium-Aluminum) 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.
Iron Chromium Aluminum alloys are widely used in industrial electrical furnace, electrical oven, home applicance, electrical heator, infrared settings, etc.
Max contineous working temperature: 1250 C.
Melting Temperature: 1500 C
Electric Resistivity: 1.42 ohm mm2/m
Diameter: 0.01mm-10mm
Has been used extensively as heating elements in industrial furnaces and electrical kilns.
Has less hot strength than Tophet alloys but much higher melting point.
Ni Cr
Nichrome (Ni-Cr) and Nickel-chromium-iron (Ni-Cr-Fe) Resistance Electrical Heating Alloys have high resistance, fine exterior antioxidation, high intensity under high temperature, good processabilities, and solderabilities. They are widely used in such industries as metallurgy, household appliances and mechanical manufacturing as heating components and in the industry of appliances as resistance materials.
Electrical Resistivity: 1.12 ohm mm2/m
Max contineous working temperature: 1150 C
Temper: Annealed
Diameter: Wire 0.02mm-1.0mm packing in spool
Rod, Bar 1mm-30mm
Main Applications
     Our high resistance electric heating alloy has a wide range of temperatures. The highest temperature can reach 1,400℃.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.
