Beschreibung
Zusammenfassung:	The SnPbBi alloy coating is suitable for making on the surface of various mechanical and electronic products and other metal products. The present invention features the introducing of certain amount of Bi to constitute the SnPbBi alloy coating and weight composition of the alloy coating including Sn 84.5-96.5 wt%, Pb 3-15 wt% and Bi 0.2-0.5 wt%. The alloy coating features no crystal whisker growth and no low temperature isomery change and thus improved long-term product storage performance.
