Below is a list of Nickel Forgings manufacturers from Aurora, Illinois. Nickel forgings are the product of a metallurgical process in which nickel is given a particular shape by the application of a strong compressive force. The pressure applied during the forging process not only shapes the nickel but also reorients its grain structure to follow the shape of the piece, making the forging much stronger. Nickel is a hard, ductile and magnetic metal, silvery white in appearance with a slight golden tinge.
