Nickel Alloys

Nickel alloys generally fall into three categories – heat resistant alloys, corrosion resistance alloys controlled expansion alloys. A wide variety of alloys have been developed often with specific applications in mind. Aerospace, Oil & Gas, nuclear and petrochemical industries are all major users of these alloys although they are used in many other harsh or extreme environments.

Available Products

ALLOY 200/201

Commercial pure (99.6%) wrought nickel alloy with good mechanical properties and resistance to a range of corrosive media. Alloy 201 has lower carbon content to prevent embrittlement at temperatures over 315°C.

UNS
BS

N02200/N02201
3072-76 NA11/NA12

ALLOY 276

A nickel-molybdenum-chromium alloy with a tungsten addition that has excellent resistance to corrosion in a wide range of severe environments. The high molybdenum content confers very high pitting and corrosion resistance.

UNS
