Nickel silver alloy and processing technique
2004
This invention relates to a zincum-white copper alloy and its processing technique. It comprises of 67~69wt% of Cu, 14~16wt% of Ni and 15~19wt% of zincum. Due to the creativity in weight percentage of the Cu-Ni-Zn ternary alloy in this invention, the alloy shows a considerably silvery color, an outstanding strength, wear resistance, corrosion resistance and discoloration resisting properties. This invention stressed a raw materials cost as low as possible, meanwhile assures excellent founding properties, corrosion resisting properties and coin processing properties.
