Minimum substrate thickness required for aluminum to be anodized




April 17, 2013

Q. Does anyone know if there is minimum material thickness required for anodic coating class 2 or 3.
I have cartridge that needs to be coated on inside. There is a "U"-shaped .063 thick divider inside the cartridge that divides it into two chambers as such that it has air gap on top and bottom of the divider. Manufacturer says that wall is too thin and acid will eat through the wall when they will try to achieve a uniform coating on inside.
Is this a true statement?

A. Hi Dmitriy. Aluminum foil can be anodized, so a material thickness of .063 is not inherently non-anodizable. But that doesn't mean your vendor is necessarily wrong that this part cannot be uniformly anodized without special measures being taken. Send us a drawing of the part for posting if you can.
