  • Introduction
Introduction
Adding Ni and Zn elements to the copper matrix results in a silver white alloy with excellent mechanical properties, deep drawing properties, good cold working formability, and easy cutting. It can be used to manufacture precision parts such as communication shielding forest materials, instruments and meters, medical equipment, daily necessities, and decorations.
