→5.2.1 Technical Grade Pure Nickel
===5.2.1 Technical Grade Pure Nickel===
Technical grade pure nickel commonly contains 99.0 to 99.8 wt% Ni and up to 1 wt% Co. Other ingredients are iron and manganese [[#figures11|(Figs. 3 5 – 76)]] (Tables 5.21 and 5.22). Work hardening and softening behavior of nickel are shown in Figs. 5.45 and 5.46.
One of the significant properties of nickel is its modulus of elasticity which is almost twice as high as that of copper. At temperatures up to 345°C nickel is ferro-magnetic.
