    5 mm 0Cr27Al7Mo2 Fecral Alloy Wire Oxidated Colour for Industrial Furnace Heating

     

    FeCrAl alloy has the characteristic of high resistivity,low temperature resistance coefficient,high operating temperature,good anti-oxidation and anti-corrosion under high temperature.

     

    It is widely used in industrial furnace, household appliances, industry furnace, metallurgy, machinery, aircraft, automotive, military and other industries producing heating elements and resistance elements.

     

    FeCrAl alloy series: OCr15Al5,1Cr13Al4, 0Cr21Al4, 0Cr21Al6, 0Cr23Al5, 0Cr25Al5, 0Cr21Al6Nb,0Cr27Al7Mo2, and etc.

     

    The alloy’s high resistivity and extremely low electro-motive force (EMF) versus copper are highly desired properties in precision resistance wire. It also possesses high tensile strength, high resistance to corrosion and is non-magnetic.

    The temperature coefficient of resistance of this material is very closely controlled by the addition of aluminum, manganese and silicon combined with critical processing controls.

    FeCrAl alloy is supplied in the annealed and heat treated condition to ± 5 ppm in the temperature range of -67°F to 221°F (-55°C to 105°C). This results in very stable resistance.

    Although FeCrAl alloy is the only high-resistance, low-TCR alloy on which extensive stability tests have been conducted, EVANOHM alloy S is heat treated in the same manner and is believed to have equal stability because its properties are produced by the same short range ordering as FeCrAl alloy.
