Commercially pure Nickel alloys find their main applications in chemical processing, automotive, electronics, and electrical sectors. These alloys offer good thermal conductivity, mechanical properties, resistance against many corrosive environments, in particular against caustic alkalis, low electrical resistivity, and good magnetostrictive properties. For instance these alloys can be used for heat exchangers in corrosive environments. In case mechanical parts require excellent corrosion and strong magnetic properties, pure wrought nickel is the best option among materials with high ductile properties at wide range of temperatures.
Our Alloys
- Nickel 200 (UNS N02200 , Werkstoff Nr 2.4066) – is the most widely used standard grade of unalloyed wrought nickel. It offers excellent corrosion resistance, good mechanical, magnetic and magnetostrictive properties and useful thermal and electrical conductivities.
- Nickel 201 (UNS N02201 , Werkstoff Nr 2.4068) – is a low carbon variation of Nickel 200 and has a very low work hardening rate which allows it to be easily cold formed. It also offers better creep resistance and is preferred over Ni 200 for applications that experience temperatures over 600°C.
- Nickel 205 (UNS N02205 , Werkstoff Nr 2.4061) – is used for applications similar to those of Nickel 200, but mostly where higher purity and conductivity are required. it is most commonly used for the anodes and grids of electronic valves, magnetostrictive transducers, lead wires, transistor housings and battery cases.
- Nickel 211 (UNS N02212 , Werkstoff Nr 2.4110) – is similar to Nickel 200 with manganese addition to improve resistance against sulphur at high temperatures. This allows for the use of this alloy in applications where sulphur is present in heating flames, such as in proximity to glass seals. It also retains higher strength than Nickel 200 at higher temperatures. This alloy is mostly used in lead wires, supporting components in lamps and cathode-ray tubes, and electrodes in glow-discharge lamps.
- Nickel 212 (UNS N02212 , Werkstoff Nr 2.4110) – This nuance of nickel preserves all the particularities of pure nickel but has been lightly strengthened with an addition of manganese. It is mainly used for cold connections but also for electrical and electronic applications such as lead wires, supporting components in lamps and cathode-ray tubes, and electrodes in glow discharge lamps. This alloy is similar to Nickel 211.
