: After anodizing 6061 we get a chalky look on the parts, supplier says its from corrosion,tried wiping parts down after machining and now they say its bad material causing corrosion after anodizing. Any ideas what to look at?
: thank you In advance

6061 is non AQ, however we have obtained excellent results anodizing this alloy. This maybe a problem with the following:
Corrosion
Machining solutions absorbing into the parts
Dirty seal bath
