This specification covers the requirements for the electrodeposition of tin-zinc alloy plating.
This plating has been used typically as a corrosion resistant plating where cadmium cannot be used, as a replacement for tin plating where tin whisker growth is a concern, a coating for fasteners where thread lubricity is desirable, and for parts which are to be joined using tin-lead solders, but usage is not limited to such applications.
Plating covered by this specification is classified as follows:
Type 1 - As plated
Type 2 - With supplementary surface treatment
Safety - Hazardous Materials
While the materials, methods, applications and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards that may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take the necessary precautionary measures to ensure the health and safety of all personnel involved.
