Alloy 400 Bar & Forgings

A nickel copper grade, that combines high strength and corrosion resistance.

Alloy 400 is a ductile, nickel copper based alloy comprised essentially of two thirds nickel and one third copper. Alloy 400 is known for resistance to a variety of corrosive conditions, including alkalies (or acid like substances), saltwater, hydrofluoric acid and sulphuric acid. Other advantages of using this alloy are its toughness and high strength over a broad temperature range; it can also be manipulated to become magnetic if desired.
