Features and Application Notes
ISA
®
13 is known for low resistivity and a relatively low temperature
coefficient, as well as its relatively high corrosion resistance. It is
used for low-value resistors and for heating wires and mats in heating
cords and in heating cables. The maximum working temperature
in air is +200 °C. ISA
��
13 can also be used as welding wire, e. g.
for building-up welding in copper-plated steel-tanks, as well as for
tube-weldings.
Form of Delivery
ISA
®
13 is supplied in the form of round wires in the range 0.05 to
8.00 mm Ø in bare or enamelled condition, flat wires, stranded wires
and ribbons.
1) ISA
®
13 is a registered registered trademark of Isabellenhütte Heusler GmbH & Co. KG.
2) This value applies to wires of 2.0 mm diameter. For thinner wires the minimum values will substantially increase, depending on the dimensions.
Notes on Treatment // ISA
®
13 can be worked easily. This alloy
can be soldered and brazed without difficulty. All known welding
methods can be used.
