LVEP “lider Electrik” provides high-resistance precision Cr23Al5Т, Cr23Al5, Cr15Al5 alloys supply under GOST 12766.1-90 and GOST 12766.2-90. Total output has quality certificates
Fecral is alloy that consist of Cr (12–15 %), Al (3,5–5,5 %), Si (1 %), Mn (0,7 %) and Fe
Fecral combines heat resistance with high electrical resistivity (1,15–1,35 mkOm*m); fusion temperature is 1470 °С; denity - 7,3 g/sm3. It has high hot and cold deformation technological plasticity and produced in form of wire or ribbon for heating spiral manufacture
Application. Fecral wire is used not only as household or industrial electric appliance spirals, but in heating constructions (ventilators, fans, fan heaters, convecting heaters and so on)
Cr15Al5 is used for heater furnaces, household electric appliance and thermal action devices
