Tin Plated Copper Bar

High humidity or moisture content areas and marine and offshore saline atmospheres.

Tin plated copper bar.

However bare copper bar begins to oxidize at higher temperatures and copper oxide has poor electrical conductivity. Tin plating parts allows for exceptional solderability for power electronics. Tinning protects the copper and protects the earth bars from the formation of copper oxide tin effectively prevents oxidation. Tinned copper earth bars could be used in external applications or where atmospheric conditions are more severe than normal i e.

In most fixed bus bar applications tin is recommended. Atotech used to offer and may still offer their alstan process for plating aluminum directly with tin skipping the copper plating step. Tin plating is the most versatile finish for copper bus bars. Hence the flashed bars can reach higher temperatures without degrading and losing their conductivity.

Tin provides excellent corrosion resistance for components susceptible to tarnish under a wide range of environmental conditions. When you choose storm to perform electroplating services you ll regain control over quality and mitigate exposure to extended lead times. Therefore copper busbar is usually plated. When working with copper bus bars plating is essential not only for longevity but also integrity and safety.

Tin plated bus bar. For both tin and silver plating anti tarnish is important to keep the surface clean and conductive. Tin is a soft white metal which can readily be polished scratch brushed or flowmelted to give a bright finish. The tin and silver flashing are more resistant to oxidation than bare copper.

Tin plated copper busbar helps upgrade design and provide the best quality for switchgears switchboards electrical panels power transformers and busducts by. Since 1999 storm has been electroplating right on premises. Yes entire manufacturing plants have been devoted to making aluminum bus bar and plating it with copper. When the plated copper components are returned for testing even the slightest scratch in the plated surface can mean a failed inspection.
