Anodizing Cast Aluminum - Finishing

Mar 02, 2021 Cast aluminum contains a lot of garbage that isnt aluminum and will not anodize. You can somewhat improve the situation by de-smutting before anodizing, with acids tailored to the specific contaminants (like nitric acid for the copper, fluoride-bearing acids for the silicon), but youre unlikely to get great aesthetics from anodized cast aluminum.

Anodizing Die Cast Aluminum Alloys Products Finishing

Aug 01, 2004 I am interested in finding some information about anodizing an aluminum die cast parts. The two alloys I am looking at are 360F and 380F. Are there any aluminum die cast alloys that would take an anodized finish better than others? I am planning on having the parts polished before the finishing operation.

Anodizing On Cast Aluminum (ADC 12 grade)

I am not expert in Aluminum Die casting, but I have been doing anodizing on ADC 6(5xxx)- Magnesium Alloy, cast parts. ADC 12, cast parts also we have tried, but it is a Silicon alloy not suitable for anodizing, finish as well as the SST results are problematic there.

More on Anodizing Die-Cast Aluminum Alloys Products ...

Feb 01, 2009 Most die-cast alloys are high in silicon with the exception of the Aluminum Association designated 200 series alloys. Silicon is not soluble in the aluminum matrix and does not anodize. So with high-silicon alloys (usually above 7 or 8% silicon) the anodizing can result in a brownish gray or black, sometimes ooty appearance.
