VP Finish’s Tin Plating is widely used to impart a ductile and corrosion resistant finish while also increasing solderability and conductivity of the substrate. It is also an excellent choice when resistance to harsh acid/base chemicals is desired. Our Tin Plating is an electrolytic process that deposits a single layer of lead free tin over an underlayment of Copper Plating on many metal substrates.
Tin
Types
- Bright Tin
- Matte Tin
Both our Tin Plating processes are lead free, low organic occlusion coatings that are both solderable and corrosion resistant over a wide range of conditions. Our Bright Tin Plating provides a deposit that is a brilliant whitish silver while our Matte Tin provides a brightener free white matte finish.
Substrates
The following are just some of the machined part substrates we can successfully deposit Tin Plating on:
- Steel
- Stainless Steel
- Aluminum
- Brass and Copper Alloys
- Beryllium Copper
- Cast Iron
- Tungsten
Grades
- Commercial Grade
- Commercial Grade with Certification (RoHS)
- Specification Grade with Certification
NOTE: Both types of our Tin Plating are Food Grade and RoHS compliant coatings.
