What are the benefits of silver plating on spring materials?

(1) The hardness is high but the compression ductility is poor;

(2) Its G value is greater, so the stiffness of the torsion spring belt is greater;

(3) Better linearity, better weldability and greater resistance coefficient;

(4) Its E/G ratio is slightly smaller than that of tin zinc bronze, so its amplification ratio is slightly smaller than that of tin zinc bronze.
