Low Price Solid Nichrome FeCrAl OCr25Al5 resistance wire Alloy Ribbon Flat Electrical Wire
Iron Chromium Aluminum alloy wires have high resistance, low temperature coefficient of electric resistance, high operating
temperature, and good corrosion resistance under high temperature, especially under the atmosphere containing sulfides.
Iron Chromium Aluminum alloy wire possesses good oxidation and heat resistance.Iron Chromium Aluminum alloy wires are
creep-resistant over a wide range of temperature, which is another of their important qualities. Iron Chromium Aluminum
alloys wires have several potential advantages, such as lower raw-material cost, superior oxidation resistance, lower density,
and lower thermal expansion coefficient than the Ni-base super-alloys.However, Iron Chromium Aluminum Alloy wire has less
hot strength than nickel alloys but much higher melting point and lower price. After being heated the alloy's plasticity becomes
bad, easy brittleness, not to be easy to weld. However, If can be reasonably used, also be a kind of ideal electric heating material.
Iron Chromium Aluminum alloy wires are made of iron chromium aluminum base alloys containing small amounts of reactive
elements such as yttrium and zirconium. The high aluminum content, in combination with the high chromium content causes
the scaling temperature to increase up to 1425ºC (2600ºF ); Iron Chromium Aluminum alloys also have excellent oxidation
properties at 800-1300ºC because of the formation of a highly protective Al2O3 scale.
