Detail:

The high demands placed by the automotive, electric and electronics industries on connectors and stamped grids, such as low insertion forces, good anticorrosion protection and 

good solderability, require the materials used to have surface treatment. Accordingly, copper and copper alloys are coated with a variety of metals,  of which pure tin is frequently 

selected for the surface coating. Pure tin is the first choice as surface protection for all connector and stamped grid materials, not only because of its properties, but also the cost 

advantage over precious and semi-precious metals.
