EFINEA is a leading supplier of electrical Nickel 205 (UNS N02205) and Nickel 270 (UNS N02270).


Nickel 205 is a wrought nickel with properties similar to that of Nickel 200. The difference in chemistry provides Nickel 205 with a higher magnetostrictive coefficient and Curie temperature. Nickel 205 is known to exhibit excellent mechanical, electrical and corrosion-resistant properties as well as good oxidation resistance.


Nickel 270 (UNS N02270) is produced via powder metallurgy methods. This high-purity material contains a minimum of 99.97% nickel. The chemistry specifications indicate a 0.001 % maximum limit on cobalt, magnesium, chromium, titanium, sulfur, silicon, manganese and copper. The limit on iron is 0.005% along with a 0.02% limit on carbon. The high-purity of Nickel 270 results in a lower coefficient of expansion, electrical resistivity, Curie temperature coupled with greater ductility than the other grades of nickel. In addition, Nickel 270 has a low base hardness and high ductility. It is essentially free from non-metallic inclusions. These properties have proven to make Nickel 270 an advantageous component in select electronic applications.
