CHROMIC ACID ANODIZE - TYPE 1
KEY BENEFITS
- Chromic anodize yields the thinnest coating - Primarily used on parts that have very close tolerances, Chromic anodize will only build up between .00005 and .0003 max.
- Chromic anodize is an excellent choice when a part is complex and difficult to rinse.
- Chromic anodize reduces the fatigue strength of the aluminum.
- Chromic anodize resists corrosion – Surtronics test results on 6061 aluminum indicated that the chromic anodize treated surface withstood corrosion in a five percent salt spray test for 336 hours. Results vary depending on the alloy of the material and the surface finish.
- Chromic anodize provides an excellent paint base - Chromic anodize is well suited for use as a primer base prior to painting using conventional spray painting procedures.
TANK SIZES
Our current size limits for Chromic anodize processing is 24" X 24" .

MATERIALS
Aluminum alloys
DISSIMILAR MATERIALS
Aluminum parts which require installation of dissimilar materials (steel bushings, dowel pins, ect.) should not be installed prior to processing. However these materials can be masked using the best available techniques, but this type of processing can only be done at the customers risk.
When considering chromic acid anodize, it is important to consult with Surtronics to ensure receipt of a satisfactory product. Consider the following:
- The application of the component
- Environment of use
- The aluminum alloy and temper
- Corrosion and hardness requirements
- Thickness range
- Final dimensional tolerances allowances
- Optimum location for racking
