Hii.... Want to knw whether Nickel Alloy 200 is used to make the body parts of the aircraft??? I have got an article related to the same from this link - http://www.regentsteel.com/nickel-alloy-201.html
Nickel alloys, such as Inconel, are generally used in the engines of turbine aircraft where their high temperature, corrosion, and oxidation resistance are invaluable. I've worked with Inconel at UW-Madison's Supercritical Water Loop; it's an amazing metal.
