What is electroplating lead-tin alloy

Lead-tin alloy plating is widely used in industry. By changing the concentration ratio of two metal ions in the plating solution, various lead-tin alloys with different lead and tin contents can be obtained. Alloys containing 6% to 10% tin in the coating are plated on steel strips to improve corrosion resistance, solderability and adhesion to paint, and have good lubricating properties; coatings containing 15% to 25% tin are commonly used in Surface lubrication, adhesion and soldering; alloy coating containing 45% to 55% tin can be used to prevent corrosion of seawater and other media; coating containing 55% to 65% tin can improve the solderability of the surface of electronic components. Adding 1% to 3% of lead to pure tin can prevent the formation of "tin whiskers". The content of tin in the lead-tin alloy coating increases with the increase of tin content and current density in the bath.

1) Prevlaka od legure s masenim udjelom kositra od 5% do 15% ima dobre antikorozivne performanse i performanse podmazivanja, a često se koristi za antikorozivnu zaštitu čeličnih proizvoda.

2) Prevlaka od legure s masenim udjelom od 6% do 20% kositra ima izvrsne performanse smanjenja trošenja i često se koristi za galvanizaciju na površini kliznih ležajeva.

3) Prevlaka od legure s masenim udjelom od 60% do 65% kositra ima izvrsnu otpornost na koroziju i lemljivost, a često se koristi za galvanizaciju tiskanih ploča.

4) Prevlaka od legure s masenim udjelom kositra od 75% do 90% ima dobru lemljivost i često se koristi u galvanizaciji elektroda elektroničkih komponenti.

5) If 1% to 3% lead is added to pure tin plating, it can effectively prevent the formation of tin whiskers.
