Tin - Zinc anti-corrosion electrolytic treatment
Tin - Zinc treatment consists of a co-deposit of tin and zinc by eletrolytic way in an alkaline medium without cyanide.
This breakthrough process offers a unique combination of anti-corrosion properties (> 1000 hours of resistance to salt spray test), electrical conductivity and solderability (very close to those of silver plating). The tin content of the coating is 65 to 85% by mass.
An automated line for medium and large series.
An automated line for very large series planned for 2023 (E-Volution 2 project, winner of the France 2030 award).
Operation of our production lines 7/7 and 24/24.
Adapted for the development of electromobility with the search for the best technical and economic compromise for very demanding applications (anti-corrosion, electrical conductivity, etc.).
