4 OVERVIEW
Nickel
Commercially pure or low-alloy nickel has characteristics that are useful in several fields, notably chemical processing and electronics. Nickel is highly resistant to various reducing chemicals and is unexcelled in resistance to caustic alkalies. Compared with nickel alloys, commercially pure nickel has high electrical and thermal conductivity. It also has a high Curie temperature and good magnetostrictive properties. Annealed nickel has a low hardness and good ductility and malleability. Those attributes, combined with good weldability, make the metal highly fabricable. Nickel has a relatively low work-hardening rate, but it can be cold worked to moderately high strength levels while maintaining ductility.
Nickel 270
Nickel 270 is a high purity grade of nickel made by powder metallurgy. It has a low base hardness and high ductility. It is essentially free from non-metallic inclusions.
Nickel 270 is non hardenable by heat treatment.
