Features and Application Notes
ISA
®
-CHROM 60 is especially characteri zed by high resistivity and
high resistance to oxidation and chemical corrosion. The alloy is
suitable for high-value elec trical resistors and for heating wires for
any application, also for heating cords and cables. The maximum
working temperature in air is +600 °C when used for resistance
wires and +1,150 °C when used for heating wires.
Form of Delivery
ISA
®
-CHROM 60 is supplied in the form of round wires in the range
0.01 to 1.00 mm Ø in bare, oxideinsulated or enamel led condition,
fIat wires and stranded wires are also manufactured.
1) ISA
®
-CHROM 60 is a registered trademark of Isabellenhütte Heusler GmbH & Co. KG.
2) These values apply to the state after rapid cooling.
3) The resistivity of nickel-chromium Alloys can be modified by special heat treatment (see Technical information).
4) This value applies to wires of 2.0 mm Ø. For thinner wires the minimum values will substantially increase, depending on the dimension.
Notes on Treatment // lSA
®
-CHROM 60 can easily be spot-
welded. Under certain conditions brazing and soldering is
possible (see Technical Information).
