Hi, I have a few questions about hard anodizing.

1. How many volts do I need to use?
2. What is the current density?
3. How well will the dyes come out, compared to room temperature anodizing?
4. What is the sulphuric acid concentration?
5. For how long do you leave the part in?
6. How can you test the thickness of the coating?

Thanks
Wayne
