A series of fishing weight alloys is designed from the Tin based substrate, which is a non-toxic and environmental friendly metal. This series of 6 fishing weight alloys are: (1) Tin & Silver; (2) Tin & Copper; (3) Tin, Silver & Coppe r; (4) Tin & Antimony; (5) Tin & Zinc; (6) Tin; (7) Tin & Nickel; and (8) Tin, Co pper & Nickel. These 6 alloys are non-corrosive when exposed to sea water, so that if it is chipped or broken, the environmentally safe Tin-based alloy of the weight will not contaminate the environment.
