C19160 alloy

C19160 is a kind of precipitation strengthening alloy. Through solid solution and aging at a certain temperature, the dispersion distribution of phosphorus and nickel compounds will be precipitated in the material matrix. The precipitation of the compounds improves the strength and conductivity of the alloy. Then through cold deformation with a certain processing rate, the tensile strength of the material can reach up to 700MPa, and the material has good electroplating performance and corrosion resistance.
