The study use a company"s production of electroplating nickel plate as the object, studied the mechanics performance of the electrodeposition of nickel:At the same time in order to explore the mechanical behavior of the metal plastic deformation mechanism, in particular, on the different degree of cold rolling deformation.The experimental results show that:Electroplating nickel exist wide crystal,Size is about 0.5μm～1.5μm,At the same time there is growth twin.The average tensile strength from 385 MPa to 461 MPa,In vertical beginningless product direction has reached the lowest (385 MPa); in parallel beginning product direction has reached the highest (461 MPa).
