Clear Chromating
Clear chromating
Clear chromating is a chrome (VI)-rich chromating layer for aluminium components
The clear chromating process is a chemical surface treatment/conversion-covering that preserves and supplies the surface with new chemical and technical properties.
Advantages:
- Used for partial corrosion protection
- Especially good adherence ability
- Is not damaged when bent, etc.
- Temperature resistance at approx. 130 °C
- The chromating layer is insoluble in water and organic solutions – but can be dissolved in strong acids and alkalis.
- Weak electric resistance that does not influence welding options, for example
Application:
- Instruments, office equipment, electronics, etc.
Structure and appearance after treatment:
- The impression of metal is retained
- The chrome layer is transparent
- The surface takes on an appearance according to the treatment chosen
Layer thickness:
- The layer thickness is typically around X my depending on the treatment time
- The weight of the layer is around X to X g/m2
Colouring:
- Cannot be coloured
Alloys:
- The majority of alloys can be used
Standards
Clear chromating fulfils the requirements:
- DIN 50939
