SurTec 650

What is SurTec 650?

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.


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.
