| Zusammenfassung: | Improved alternatives to cadmium plating have been sought for many years. Since cadmium is being banned by more and more governing agencies, it is imperative to find alternatives with as good a corrosion resistance as cadmium. One such material is tin-zinc plating. It combines the protection of tin and the sacrificial effects of zinc in one coating. The best coating is one with 70-80% tin with the balance zinc. It accepts chromate conversion coatings to further enhance its corrosion resistance. Tin-zinc also has excellent resistance to bending and crimping, and is solderable. Added advantages are that the tin in the deposit does not form whiskers or divert to beta tin (tin pest) and it has good wear resistance. |
