Type II vs Type III Anodizing of 2024 Aluminum

A. Type III anodize of 2024 is a risky venture due to the higher concentration of copper within the alloy. Not to say it can't be done, we do it often, but the risk of material degradation is increased. To answer your other question, 7075 would be more appropriate for a type III coating. -Bill.

Hard anodize for 2024 Al alloy

Of course, the 2024 alloy can be hard anodized. It is a tad more difficult but you can anodize it nonetheless! You can control your tank: T = -2 deg C to 0 deg C Free H2SO4 : 200 to 230 g/l, at around 210 g/l, you obtain the hardest coating. Current density = about 40 Amps/sqft.
