Re: VEX PRO. To use it or not to use it.

Most Aluminum materials that we deal with here that are required for applications such as gears would be made from 6XXX or 7XXX Aluminum.

MIL-8625 T2-C2 Anodizing is a general use dyed Sulphuric anodize process. Anodizing being inclusive does not change dimensions of a machined part until you strip the coating off.

Anodizing being an electrochemical process is subject to all the same current density pitfalls as any other electroplating process. You will have a thicker coating in the highs and thinner in the lows. In the case of a gear the top of the tooth would be high current the ID bore would be low.

This info is just basic stuff. Finishes are engineered just like material choice, many times they go hand in hand.

Take this info for what you may, it never hurts to learn a little.
