Konstantan / Kupfer-Nickel-Legierungen

Nickel Copper Alloy. These alloys contain Nickel with Copper and small amounts of Iron and Manganese. A typical alloy within this range is the 400 grade (UNS N04400). This contains nominally 65% Nickel, 32 Copper, a maximum of 2% Manganese and 2.5% Iron Alloy K500, also found within this group of alloys has additions of Titanium and Aluminium in order to enhance its strength and hardness after precipitation hardening. These alloys are used where a higher strength is required compared to pure Nickel. They have a wider range of environments where they resist corrosion but in some specialised applications, where strong alkali contamination is likely, then Nickel would be superior. These alloys are used widely in Oil refining and Marine applications where long corrosion-free life is required. Good thermal conductivity lends the use of these alloys to the manufacture of heat exchangers, particularly where sea water is involved.
