Aluminum is damaged by alkaly bath so i have to use the acid or neutral bath.
I want to use neutral bath and I tried many times, but i couldn't because it is hard-anodized aluminum.
I used this.
CuSO4 (main metal source)
NaH2PO2 H2O (reducing agent)
C6H5Na3O7 2H2O, NH4Cl (complex agent)
NiSO4 6H2O (catalyser for the oxidation of the reducing agent)
NH4OH (adjust pH to neutral)
