Nickel 205 & 270 Properties

EFINEA knows that the mechanical and physical properties are one of the key factors in the selection of the grade of Nickel for an application. As a guide in your evaluation, we have compiled the typical physical and mechanical behaviors, along with the chemistry and specifications for these two grades we supply, Nickel 205 and Nickel 270.

 

For those interested in Nickel 270, we have included additional metallurgical properties as a guide for this 99.97% high-purity nickel. You will find mechanical property data by form (rod, sheet, strip) and condition (hot finished, cold rolled, annealed). Mean linear expansion, thermal conductivity, and electrical resistivity for Nickel 270 is also within this section.
