MANUFACTURING
Manfacturer of mechanical components, housings and entire assemblies in metal and plastic.
Passivation is a galvanic process for creating conversion layers. By treating metal surfaces with chrome(VI)-containing solutions, the corrosion protection and adhesion are increased. Aluminum, magnesium and zinc-coated steels are suitable for passivation. The layers which are less than 1 µm thick are electrically conductive and can be soldered. G.W.P. offers yellow passivation, green passivation and transparent passivation in accordance with DIN EN 12487. We can offer chrome(VI)-free alternatives (colorless) for orders in conformance with RoHS.
Passivation is particularly appropriate for aluminum components that must be conductively connected (housing parts, etc.).
