Hi - I have a CNC Mill and I have been CNC'ing aluminum. I have a few questions...

Q1> Can aluminum be hardened like steel? I recently took a machining class and learned how to harden steel. But was thinking it might not work with aluminum. Wanted to be sure though.

Q2> Also - some items I see where people mill out a section of sluminum and place a piece of cut carbon fiber down into the aluminum for looks and to reduce over all weight. I want to do this with one of my projects but want to know what kind of glue or what is used to hold the carbon fiber onto the aluminum like that?

Thanks!!! :cheers:
