Passivation of aluminium, stainless steel and other materials
Adruu specialises in yellow passivation of aluminium parts. Since yellow chromate contains hexavalent chromium and, as a result, is forbidden, Adruu has developed a chromium free passivation replacement treatment. Contrary to yellow chromating, yellow passivation is RoHS compliant.
Other materials, like stainless steel, can also be passivated on our large line.
