Alloy X15S5 is a triple compound of iron, aluminum and chromium. Fechral X15S5 contains about 15% chromium and 5% aluminum, the remainder is iron and additives. This combination provides a sufficiently high melting point of the material, which significantly expands the field of its application.

The basis of the alloy is cheap iron, and the addition of chromium and aluminum increases its resistance to corrosion caused by both the environment and chemical agents of industrial importance. Chromium and aluminum also provide the ability to work in elevated temperatures. These characteristics may vary slightly depending on the percentage of the main elements in the alloy and the presence in it of various additions.


A successful combination of components in the composition of this type of material ensures its reliable performance in conditions of high temperature conditions. High resistance to electric current makes it possible to use the alloy in the electrotechnical sphere and in the production of heating elements of various equipment, and low density provides a lower weight of parts and assemblies constructed from such raw materials. If we compare it with nichrome, then the economy in weight from using fechrali will be about seventeen percent.


Most often this kind of material is used in the manufacture of various household appliances. Also, such raw materials are in demand for the manufacture of industrial furnace and heating equipment with a not very high temperature in the working area. The only significant drawback of such an alloy as fechral X15Y5 is its increased brittleness. This property makes it difficult to manufacture wire products and ribbon semi-finished products from a similar material.
