Fecral wire Cr23Al5


A fecral wire is an alloy that consists of iron, chrome, aluminium with masteralloys of manganese and silicon. It became an indispensable material in a manufacturing of electric appliance heating elements and industrial electrical furnaces. It is utilized also in convection heaters, blow heaters, hair driers, rheostats, and resistors while producing the nests of resistance. A huge application is conditioned upon a high temperature of melting and excessive specific real resistance.

Main properties of Cr23Al5

Fecral is an ideal alloy with an excessive specific real resistance (1,20−1,30 Ohm-mm2/m) which possesses heat resistance up to 1450 °C. It is claimed to be indispensable at temperature extremes. These properties allow using this alloy extensively while manufacturing the heating units. Such wire possesses a variety of further advantages: it has a perfect corrosive resistance on air, in argon, in a vacuum, oxidizing, sulfur-containing and carboniferous environments. It shows not very high relative density (7,2 g/cm3), but it has a great yield limit, which allows using this with a minimum diameter wire. It also has an excellent firmness against mechanical loads. The main advantage is its cost: it costs just 20% of a similar materials price. Among the demerits of alloy, there is only its frailty, which essentially complicates a process of a manufacture strips and thin wires. It can be eradicated with a help of nickel miscellaneous or analogues elements, but hereby final cost of a material will be increased.


Because of alloy frailty, a method of a cold work can not be applicable. Consequently, for drawing a filament are used special energy-intensive methods, which reflect on a pricing of alloy. At a manufacture, usually, are used methods of drawing and pressing. At a later stage, a finished product is going to be coiled or spooled for further use.

Fecral filament is one of the most popular and preferable material among the industrialists. Winning consumer properties, excellent technical properties and low price gain a contemporary market. Nowadays, fecral has almost displaced nickel from this section. In comparison with nichrome, a low fecral wire Cr23Al5 price is caused by using cheap aluminium instead of expensive nickel. A cost depends on a diameter.
