Anodize Color issues
We do typcially have an approved color range. That is fine, but what I have found is that even within the same batch (all anodized at once) there is a variation. For instance an assembly with A, B, and C anodized parts. The vendor will anodize A, B , and C all together, but we will still see...- Eng5100

Aluminum Surface Finish cost comparison
I might suggest tapping into the AL or using PEMs. Al isn't great for grounding, but if it this is related to ESD issues at all then I would consider taptite screws into the Al or machince screws into PEMs. Order for your options may be 2, 3, 4, 5, 1 least to most expensive. Most depend on...- Eng5100

Anodize Color issues
Ah...words I haven't been around since I finished my materials engineering degree! So, there is no great way to control color variation unless the extrusion vendor is also the anodizing vendor. I suppose even then you can't always guarantee the alloy homegeneity from billet to billet. Thanks!- Eng5100

Anodize Color issues
I have found that aluminum extrusion vendors have a hard time controlling the anodizing process on seperate mating parts even when those parts are anodized at the same time. I believe this is due to the variance in the actual aluminum alloy billet (percent of each element in the alloy) rather...- Eng5100
