Description |
Advantages |
Disadvantages |
|---|---|---|---|
| Chromated | A layer of chromate coating is applied. | - Excellent corrosion resistance<br>- Enhanced paint adhesion | - Contains hexavalent chromium (environmental concerns)<br>- Requires additional safety measures |
| Non-Chromated | Uses alternative chemicals to provide corrosion resistance. | - Environmentally friendly<br>- Good corrosion resistance | - May have slightly lower corrosion resistance than chromated |
| Oiled | A thin layer of oil is applied to the surface. | - Temporary corrosion protection<br>- Facilitates further processing | - Needs to be removed before painting or further coating |
| Dry | No additional surface treatment after the coating process. | - Cost-effective<br>- Ready for immediate use in some applications | - Limited corrosion protection |
| Anti-Fingerprint | Special coating to prevent fingerprint marks and smudges. | - Maintains aesthetic appearance<br>- Provides additional corrosion protection | - May increase production cost |
| Phosphated | A phosphate conversion coating is applied to enhance adhesion. | - Excellent paint adhesion<br>- Additional corrosion resistance | - Additional processing step<br>- Environmental considerations for disposal |
| Passivated | A passivation layer is applied to enhance corrosion resistance. | - Good initial corrosion resistance<br>- Cost-effective | - May not be as effective as chromated coatings in harsh environments |
| Painted/Pre-painted | A layer of paint is applied over the Aluzinc coating. | - Aesthetic flexibility<br>- Enhanced corrosion protection | - Higher production cost<br>- Paint may degrade over time |
