Tin

Brief technical description:

• By passing a current through a component switched to a tin galvano-electrolyte, a tin coating is precipitated onto the surface of the component. The precipitated tin coating typically has a silvery-white colour and a glossy and soft surface. This decorative surface also provides good corrosion resistance, as a fine passivation layer is formed at the surface.  The method used leads to very good throwing power, so that excellent results can be achieved, even on components with a very complex geometry. The dreaded "whisker formation" effect is suppressed. This lead-free method is RoHs-compatible. Components can be finished on the rack as well in the drum. Among other materials, aluminium, steel, stainless steel, copper, brass and Zn die-cast components can be coated.

Advantages:

• Very good soldering properties, suitable for soft-soldered surfaces
• Good sealing of pipes and crimp connections (soft surface)
• For decorative and technical solutions
• Safe to use with food and drinking water

Please note:

• The tin coating is prone to fingerprint effects and may tarnish. Approximately 80% of our customers request anti-tarnish passivation. This is achieved via a post-dip solution.

Fields of application:

• Automotive and supplier industry
• Electrical industry
• Consumer (household items, decorative items, sporting trophies, etc.)
• Mechanical engineering (food industry, etc.)
