What material should be used for auxiliary anodes in acid zinc? [Mexico] 

+++++

Greetings,

I want to use auxiliary anodes in a zinc acid bath. I wonder what materials are recomended to use in that kind of bath. Maybe there are plenty of options, yet I have the restiction of availability. The materials I was thinkinking of are (in order of what is more available o easy to get to me):

Stainless steel
Nickel plated metal
Titanium

Do you have other recomendations?
Thanks four your help and advice.

Use conforming soluble zinc anodes.

The other alternatives will dissolve eventually in acid zinc contaminate the bath and give you rejects due to missed plating and contaminated electrolyte.

Replace the zinc anode periodically after inspection.
