A new lean nickel alloy has recently been introduced that has excellent oxidation and creep properties for use in industrial and automotive applications. This material has so far been used in electrical heating element applications and is now being evaluated for use in fabricated car manifolds. This alloy was specifically developed for maximum resistance to oxidation and resistance to oxide spallation when thermally cycled, which is demanded by electrical resistance heating wires. However, these properties are also useful in other applications where similar demands are required. This new alloy is also optimized with respect to creep strength, which is demanded for the resistance wire applications in order to prevent sagging and electrical shorting of the heating elements. Although the new alloy contains less than 40% nickel, it has the properties of much higher alloys and is compared to traditional 60% nickel containing alloys.
