Abstract

An alloy, adapted for use as a conductor for electrical resistors, consisting essentially of 30-45 wt. % Ni, 30-34 wt. % Cr, 25-35 wt. % Al and an effective amount of a corrosion inhibitor and stabilizer selected from the group consisting of transition metal elements and rare earth elements.

Claims

1. In an alloy, adapted for use as a conductor for electrical resistors, said alloy consisting essentially of 30% by weight to 45% by weight nickel and 30% by weight to 45% by weight chromium and in combination therewith, as a corrosion inhibitor and stabilizer, 25% to 35% by weight aluminum and at least one substrate selected from the group consisting of transitional metal elements, and rear earth elements.

2. An alloy adapted for use as a conductor for electrical resistors, said alloy consisting essentially of nickel at 33% by weight, chromium at 33% by weight, and aluminum at 33% by weight and as a corrosion inhibitor and stabilizer an effective amount of at least one substance elected from the group consisting of transitional metal elements, and rare earth elements.
