FeCrAl (Kanthal) is an alloy of chrome, ferrum, aluminium. A composition of alloy is represented in its name. Ferrum — «Fe», Chrome — «Cr», Aluminium — «Al». Ferrum constitutes a basis of alloy. Its quantity in alloy is generally more than 70%. Additionally, it compounds with mangan, silicon, and sometimes with nickel. Every variation has its marking, which depends on a content of the main components.

The main properties

This alloy combines a high temperature of melting (1500 °C) and mighty real resistance to 1,3 Ohm-mm2/m. Fairly low density (7,2 g/cm³) makes it lighter than nichrome for 17%. By virtue of using cheap aluminium instead of insufficient nickel, production cost becomes 6 times cheaper than when using nichrome. Fecral differs with a high corrosive resistance in a vacuum condition, on air, in carbon-bearing, oxidation, and a sulphuric environment. An Achilles' heel of fecral is a frailty. As a consequence, a manufacture of thin strips and wire is obstructed. This demerit can be eradicated with the masteralloys of nickel, but then a fecral alloy price becomes higher.

The most popular grades are Cr23Al5T, Cr15Al5, Cr23Al5. Usually, grade Cr23Al5Ti is used for a manufacturing of a wire, and Cr15Al5 for a manufacturing of a strip. Before buying, it is necessary to get acquainted with a marking by means of using.

Manufacture, delivery

A wire is produced with a help of pressing, drawing and cogging methods. It can be spooled or coiled. A strip is produced with a help of cogging or electrowinning methods, after which it has to be rolled. By means of «Auremo» company’s website, where is represented a huge assortment of heat-resistant alloys, including eurofecral and such grades as Cr23Al5Ti, Cr15Al5, Cr23Al5, you can become acquainted in more detail with a production, to clarify its main properties and to make an order.

International grades

Cr23Al5Ti — 875 (W-KA1) consists of 22% of Cr, 72,2% of Fe, 5.8% of AL, t° of melting 1500 °C. International name: eurofecral, Kanthal D, Alloy 815, Alchrome DK, Resistohm 135, Megapyr, Aluchrom 5, GS SY. Analogous grades: OCr25Al5, 1Cr13AL4, OCr15Al5.

Kanthal D (Cr21Al) consists of 22% of Cr, 73,2% of Fe, 4,8% of Al, t° of melting 1500 °C. An international name: eurofecral, Kanthal D, Alloy 815, Alchrome DK, Resistohm 135, megapyr, Aluchrom 5, GS SY. Analogous grades: OCr27Al7Mo2, OCr15Al5, OCr21Al6Nb, FeCrAl+Y.
