ABSTRACT:
The application discloses a method of terne coating, and a terne coated product, wherein the tin content of the terne is substantially lower than in conventional terne, without the need for other alloying elements in substitution for tin, such as zinc, antimony, silver, and phosphorus. The tin content of the terne bath is lowered below conventional percentages, to between about 2% and about 6.5% and the terne coated product, upon emerging from the coating bath, is jet finished. Such a terne coat has improved solderability and appearance with no change in pinhole frequency. Coating weight control is easier than with a terne coat having 7% or more tin in the bath.
