What are SurTec 650 and SurTec 650V?
SurTec 650 is a passivation process based on non-toxic trivalent chromium, suitable for aluminium, aluminium alloys and magnesium.
Key features include low surface resistance (electronics) and high corrosion protection on bare surfaces (aerospace).
It can be applied both to raw pieces or those already anodised to increase resistance to corrosion.
Whether you are upgrading from hexavalent chromium or optimising your current process Surtec 650 offers:
REACH, RoHS and WEEE compliance that is kinder to the environment.
SurTec 650V is designed for industries requiring robust protection, it delivers a durable, visible iridescent aluminium coating ranging from blue-grey to yellow. Used across aerospace, defence, electronics and precision manufacturing sectors.
Applications
SurTec 650 is particularly suitable for the electronics, automotive and aerospace sectors.
Also, it is recommended for pre-treatments before welding, enamelling and electrostatic painting.
