Features and Application Notes
ISA
®
-NICKEL is known for its high resistance to oxidation and
chemical corrosion. These features govern the application: Wire
cloth, connecting braids for heating elements, welding wires and
many more applications. The maximum working temperature in air
is +700 °C.
Form of Delivery
ISA
®
-NICKEL is supplied in the form of round wires in the range
0.03 to 8.00 mm Ø and stranded wires in bare condition.
1) ISA
®
-NICKEL is a registered trademark of Isabellenhütte Heusler GmbH & Co. KG.
2) ISA
®
-NICKEL is not standardized as a resistance alloy.
3) This value applies to wires of 2.0 mm diameter. For thinner wires the minimum values will substantially increase, depending on the dimensions.
General Note // Since ISA
®
-NICKEL alloy itself cannot
be used as a resistance material, but merely for accessories for
resistive components, no resistance values per meter are given.
The weight values correspond to those of ISOTAN
®
wires of the
same diameter.
Notes on Treatment // ISA
®
-NICKEL can be worked easily. It
can be soldered and brazed without difficulty. All known welding
methods are applicable.
