ZnBi2% Alloy
Zinc Bismuth Alloy
Zinc Galvanizing Alloys
Results of laboratory-scale testing showed that additions of bismuth to pure zinc provided equal drainage compared to conventional lead-containing zinc, while additions of combined bismuth and lead to pure zinc provided significant improvements in drainage.
Plant using Zn/Bi alloy reports performance equivalent to conventional lead-containing zinc, while plants using Zn/Bi/Pb alloy report reduced zinc consumption, especially in complex parts
