ISA13

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.
