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.
