FeCrAl alloy 0Cr27Al7Mo2hege termyske effisjinsjeAlchrome Alloy Resistance Wire (wurktemperatuer 1400C)
Nominale analyze
27.00 Cr, 7.00 Al, 2.00 Mo, Bal. Fe
Maksimum trochgeande wurktemperatuer: 1400 C.
Wire diameter: 0.5~12mm
Smelttemperatuer: 1520 C
Elektryske Resistivity: 1,53 ohm mm2 / m
Is wiidweidich brûkt as ferwaarmingseleminten yn yndustriële ovens en elektryske ovens.
Hat minder hjitte krêft as Tophet-legeringen, mar folle heger rylpunt.
