I search through the post and found this posting that relates to some questions I have.
I stripped and anodized some parts last night did a slow fade from color to silver anodized metal. We are extremely happy with the results however the silver anodized parts have a more matt, less shinny / glossy finish. We used the 720 rule for a max anodized layer.
After reading this post I assume cutting the anodizing time will result in a thiner layer that is shinny / glossy. If I’m using the 720 rule and I anodize a part for 120 minutes at 6 amps my coating will be .001” thick. Going by what MD said I will have to achieve a thickness of .00035 for a shinner surface. Using the 720 rule (720*.35 = 252/6Amps = 42 minutes). So if I anodize my part for 42 minutes will I achieve a shinier coating? I’m not using Ti racking but I’m using a CDW unit to attach my aluminum wire to my part, does this affect my numbers?
Finally not knowing how the thickness of an anodized layer affects the coating on the part I assume that the coating is less durable going from .001 to .00035. Is this a trade off you have to live with, finished look vs. durability?
Thanks again for your help.
