For both tin and silver plating anti tarnish is important to keep the surface clean and conductive.
Tin plated copper bar.
Tin is a soft white metal which can readily be polished scratch brushed or flowmelted to give a bright finish.
Since 1999 storm has been electroplating right on premises.
When working with copper bus bars plating is essential not only for longevity but also integrity and safety.
When the plated copper components are returned for testing even the slightest scratch in the plated surface can mean a failed inspection.
Tin plating parts allows for exceptional solderability for power electronics.
Tinned copper earth bars could be used in external applications or where atmospheric conditions are more severe than normal i e.
Hence the flashed bars can reach higher temperatures without degrading and losing their conductivity.
Silver should be used for moving bus bar parts in which arcing may be a concern.
In most fixed bus bar applications tin is recommended.
Therefore copper busbar is usually plated.
Tin plated copper busbar helps upgrade design and provide the best quality for switchgears switchboards electrical panels power transformers and busducts by.
When you choose storm to perform electroplating services you ll regain control over quality and mitigate exposure to extended lead times.
High humidity or moisture content areas and marine and offshore saline atmospheres.
Tin plating is the most versatile finish for copper bus bars.
The tin and silver flashing are more resistant to oxidation than bare copper.
Tin plated bus bar.
However bare copper bar begins to oxidize at higher temperatures and copper oxide has poor electrical conductivity.
So both tin directly on aluminum and tin on copper on aluminum are common.
Tinning protects the copper and protects the earth bars from the formation of copper oxide tin effectively prevents oxidation.
Tin provides excellent corrosion resistance for components susceptible to tarnish under a wide range of environmental conditions.
