Technical Data Sheet Alloy 200 (UNS N02200) is a commercially pure wrought nickel, with good mechanical properties and an excellent resistance to many corrosive environments. Alloy 200 has good thermal, electrical and magnetostrictive properties. Alloy 201 is exactly the same but with less carbon for hotter applications. Both Alloy 200 and Alloy 201 are generally used in food processing equipment, chemical shipping drums, caustic handling equipment and piping, electronic parts, aerospace and missile components.
