Properties and Application Notes
Alloy 90 is especially noted for low resistivity and high resistance to oxidation and chemical corrosion. It is used for low-value resistors, for heating wires and mats in heating cords and in heating cables with low conductor temperatures, as well as for tube-weldings “electrical-welding-fittings”. Ribbons are used for heating of bimetals.
The maximum working temperature in air is 400 °C.
Form of Delivery
Alloy 90 is supplied in the form of round wires in the range 8.0 to 0.05 mm Ø in bare or enamelled condition. To a limited extent flat wires, stranded wires, ribbons and sheets are also manufactured.
Notes on Treatment
Alloy 90 can be worked easily. This alloy can be soldered and brazed without difficulty. All known welding methods can be used.
