Advantages of ferrochrome electric heat alloy
High temperature is used in the atmosphere
HRE alloy of iron chromium aluminum alloy electrical highest
temperature can reach 1400 ℃, the highest Cr20Ni80 alloy of nickel
and chromium electrothermal alloy using temperature is 1200 ℃.
Long service life
At the same high temperature in the atmosphere, the chromium
aluminum element can live 2-4 times as long as nickel chromium.
Due to the high temperature and long life, the surface load of the
element can be higher, which not only makes the heating fast, but
also saves the alloy material.
Good oxidation resistance
The structure of Al2O3 oxide on the surface of ferrous chromium
aluminum alloy is compact, and it is good for adhesion of the
substrate, and it is not easy to be contaminated by the
scattering.In addition, Al2O3 has high resistivity and high melting
point. These factors determine the excellent oxidation resistance
of Al2O3 oxide film.The anti-carburizing performance is also better
than the Cr2O3 generated on the surface of nickel-chromium alloy.
The proportion of small
The ratio of chromium to chromium alloy is smaller than nickel
chromium alloy, which means that it is more efficient to use
chromium aluminium than nickel chromium when making the same
Resistivity than the nickel chrome iron chromium aluminum alloy of
high, when the design components can choose bigger specifications
of alloy materials, which is beneficial to prolong the service life
of components, it is particularly important for fine alloy
wire.When the same material is used for the same specification, the
higher the resistivity, the less the components are in the
furnace.In addition, the resistivity of ferrochrome aluminium alloy
is less affected by cold processing and heat treatment than nickel
Good anti-sulfur performance
Iron chromium aluminum has good corrosion resistance to
sulfur-bearing atmosphere and sulfur-containing substances, while
nickel chromium can be severely eroded.
Iron chromium aluminium is much cheaper than nickel chromium
because it does not contain more scarce nickel.
