Topic: newbie needs rectifier pointers

I'm a machinist and I make some parts out of 6061 aluminum that I want to start anodizing. I just bought a kit with 8 colors and some cleaner. The parts are about the size of a regular cup of coffee. I'll be anodizing two at a time but may end up doing four at a time.

What size rectifier do I need to get?




Re: newbie needs rectifier pointers

Figure out the surface area. 10 to 12 amps per sq, ft is recommended for type II anodizing.

Depending on the alloy, expect to get 15 to 18 volts.
