Purpose

This specification covers the requirements for electrodeposited tin-zinc alloy plating. 

Application

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. 

Classification

Plating covered by this specification is classified as follows:

Type 1 - As plated

Type 2 - With supplementary chromate treatment.

Grade A - Hexavalent chromate treatment, service temperature 250 °F (121 °C) maximum.

Grade B - Trivalent chromium treatment, service temperature 375 °F (191 °C) maximum. 

Unless a Type is specified, Type 2 shall be supplied. 

For Type 2 plating, if no grade is specified, Grade A shall be supplied. Processors have the option of using Grade B if permitted by the cognizant engineering organization. 

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.
