Alloy 200 (UNS N02200) is an unalloyed wrought nickel. It offers excellent corrosion resistance, good mechanical, magnetic and magnetostrictive properties and useful thermal and electrical conductivities.
Alloy 201 (UNS N02201), with reduced carbon content (0.02% max), shows better corrosion resistance at elevated temperatures above 300°C (570°F) by avoiding graphite precipitation.
These alloys are characterised by:
• excellent corrosion resistance in many alkaline media
• good mechanical properties within a wide range of temperatures
• magnetization decreasing continuously between -273 and 360°C (-458 and 680°F) and showing paramagnetism above the Curie point
