Tin plating has excellent luster and solderability, and is often used for electrical and electronic parts.
It is also used for piston parts of car engines because of its good slidability.
In addition to bright acid plating and matte alkaline plating, we also provide electroless tin plating on copper materials.

Features
Features 1Flexibility in tin plating
Tin-plated (Sn) film is flexible and malleable.
Therefore, it is often used for items that must be bent after plating and for contact parts such as crimp terminals to fill the gap when crimping.
Tin plating displays excellent low friction
Tin is soft and self-lubricating.
By applying soft tin plating on a hard material, it has the effect of reducing frictional force and improving the sliding performance of the sliding part.
As an alternative to soldering
Tin plating is also widely used as a substitute for soldering.
Conventional solder is an alloy of tin and lead, but environmental regulations have made it difficult to use lead.
Therefore, tin plating (Sn) is attracting attention as a lead-free soldering method.
