Hi my name is Dave Edwards. I am currently manufacturing some carbon fiber products and I am investigating switching to using some 7050 and 7075 series aluminum. I have read several papers on metallurgy but I still have some questions. Any help you could provide will assist me in making my choice as to which manufacturer to select. Thank you.
1. Is there a way to anodize multiple colors? To make a design integral to the metal¡¯s surface?
2. What is the difference in the composition of 7005, 7050 and 7075 aluminum?
3. How are Vickers calculated?
4. Are the benefits of Chem-Film over anodizing simply that Chem-film is more conducive to electrical transmission? Is the process cheaper or easier to do?
5. What is the difference between hard coat anodizing and clear cost anodizing?
6. Does using a bright-dip have any adverse effects on the strength of aluminum?
7. What are the benefits of integral coloring as opposed to electrolyte coloring?
8. What are the benefits and challenges of Interference coloring over Organic dyeing? I assume the cost of Interference coloring is significantly higher
9. How would you conduct QC of my production to ensure the highest quality products?
10. How would you finish aluminum if the color is more important than the strength? What if strength is more important than color?
11. What is the best method for adding a multiple color paint job over an anodized coating?
