Metal Anodization
++
I would appreciate you help me on this need. I've seen your web site and it makes me write for help. My question is about aluminium anodization. How can I get a light violet color while anodizing aluminium? Is there any lamp reflector or another thing I can use? Thank you a lot for your time.

I did not understand the reference to a lamp reflector, although aluminum is often bright dipped and then anodized as a way of making lamp reflectors. The way to get a light purple color reflector would be to bright dip, sulfuric acid anodize, dye, and seal the parts. Remember that a lot of aluminums are alloys but only aluminum per se will bright sip and anodize. So good reflectors require an aluminum grade that is fairly pure. Good luck.
