OhmAlloy135
(Common Name:0Cr23Al5, D, , Alloy 815, Alchrome DK, Alferon 901, Resistohm 135,Aluchrom S, Stablohm 812)
Fechral can most likely be attributed to metals with a very high electrical resistance, which explains its widespread use in electrical products associated with high temperatures. This article describes in detail the physical properties of the application area, various brands of fechral and types of goods in which metal is used.
Fechral itself is an alloy consisting of elements such as chrome
aluminum and iron with a small percentage of nickel of about 0.6
percent. The low content of the latter gives the alloy an
undeniable advantage over nichrome making it cheaper. With a
melting point of -1500 degrees, the fechral can withstand operating
conditions and at 1400 degrees, plus, the resistivity is 1.39 μOhm.
With a density of 7.21g / cm3, this alloy can be confidently
considered a serious competitor to nichrome.
Fechral has a high degree of resistance, which is a distinctive and
main useful feature of this alloy. It is also characterized by heat
resistance and is not prone to corrosion. The alloy is hard and
works in conjunction with various materials as well as in
aggressive environments and atmospheres. The only weak point of
fechral is the presence of iron in its composition, which makes the
alloy brittle enough, which in turn complicates the processing of
metal to obtain the final product.
OhmAlloy135 is a iron-chromium-aluminium alloy (FeCrAl alloy) characterized by high resistance, low coefficient of electric resistance, high operating temperature, good corrosion resistance under high temperature.It is suitable for use at temperatures up to 1250°C.
Typical applications for OhmAlloy135 are used in home appliances and industrial furnace,and kinds of elements in heaters and dryers.
