Tin plating on leaded bronze bushings: serious I.D. issue

Summary for tin plating on leaded bronze bushings Discussion

Tin plating on leaded bronze bushings is the focus keyphrase issue here: Sandeep Kumar reports that an acid tin bath based on stannous sulfate gives good appearance on the outside diameter, but non-uniform or no plating on the inside diameter. The thread excerpt only includes the question, so no corrective answer or agreed solution is shown in the source provided. The practical problem is therefore clearly identified as an inside-coverage issue on a leaded bronze bushing, likely related to throwing power, part geometry, or process setup, but the excerpt does not supply a confirmed remedy. Because no respondent answers are included, no named advice can be attributed from this source.
