Nickel-based superalloys are used in load-bearing structures requiring the highest homologous temperature of any common alloy system (Tm = 0.9, or 90% of their melting point). Among the most demanding applications for a structural material are those in the hot sections of turbine engines (e.g. turbine blade ).
Inconel 718 is commonly used for cryogenic storage tanks, downhole shafts, ... which are nickel superalloys (improvement over older Inconel alloys). [56] Automotive
For example, alloy 020 is designed to be resistant to sulfuric acid, and the DS Incoloy is to be used in heat-treating furnaces with reactive atmospheres and many heat cycles. Incoloy 020 "exhibits excellent corrosion resistance in chemical environments that contain sulfuric acid, chlorides, phosphoric acid and nitric acid."
Nickel aluminide refers to either of two widely used intermetallic compounds, Ni 3 Al or NiAl, but the term is sometimes used to refer to any nickel–aluminium alloy. These alloys are widely used because of their high strength even at high temperature, low density, corrosion resistance, and ease of production. [1]
The most common commercial niobium alloys are ferroniobium and nickel-niobium, produced by thermite reduction of appropriate mixtures of the oxides; these are not usable as engineering materials, but are used as convenient sources of niobium for specialist steels and nickel-based superalloys. Going via an iron-niobium or nickel-niobium alloy ...
Hiduminium or R.R. alloys (2% copper, iron, nickel): used in aircraft pistons; Hydronalium (up to 12% magnesium, 1% manganese): used in shipbuilding, resists seawater corrosion; Italma (3.5% magnesium, 0.3% manganese): formerly used to make coinage of the Italian lira; Magnalium (5-50% magnesium): used in airplane bodies, ladders, pyrotechnics ...

Alloys of nickel are the most common but includes iron aluminum alloys. [1] Applications include high temperature turbine blades and heat exchanger tubing, [2] while steels are used in nuclear applications. [3] ODS materials are used on spacecraft to protect the vehicle, especially during re-entry. Noble metal ODS alloys, for example, platinum ...
