Nickel alloys in Aerospace and defense

Inconel alloys are comparable to stainless steel. Alloys vary in values like corrosion resistance and tensile strength.
Alloy 718

Inconel 718 is the most widely used nickel superalloy in aerospace due to its excellent mechanical properties and corrosion resistance. 718 is an age-hardenable alloy that is often used for fasteners, sheet metal parts, and instruments in aircraft.
Alloy 625

Formed from molybdenum and columbium, Nickel Alloy 625 is used for its high strength and corrosion resistance. It is also known for its excellent weldability and high-temperature resistance. It is often used in plane engines and aircraft exhaust systems.

Whether they are made from stainless steel, titanium, nickel, or other metals, high-performance alloys are widely used in aerospace and defense manufacturing. Leading suppliers of aluminum aircraft extrusions can help a manufacturer choose the right alloy for a particular application.

Top suppliers also offer add-on capabilities like vendor-managed inventory and secondary processing so that manufacturers can get all of their materials from a single supplier. “We offer manufacturers a one-stop-shop for their kitting needs so that they do not have to break up a kit of materials across different suppliers,” Barron said.
