Nickel alloys for aerospace use are selected based on their ability to resist extremely high temperatures, corrosion and constant wear, and for their magnetic properties.

Titanium is the metal of choice for offshore oil rigs where its corrosion resistance makes the metal ideal for prolonged exposure to salt water and corrosive substances.

Titanium, which is relatively resistant to corrosion by a number of chemicals and seawater, is utilized widely in plants, such as liquefied natural gas (LNG) plants, seawater desalination plants, and chemical plants.
