Welding/soldering SS or brass to Al, help please.

Hi all,

I've got a project going where it would be advantageous to either weld or solder stainless steel or brass/bronze to Al. I know welding Al requires Tig, and soldering Al is an art form too, and SS ain't no walk in the park either. But, brass and bronze I have at home, and would like to know if these copper based alloys can be welded/soldered successfully to Al, and without major galvanic problems in the long term.

I'm also open to other ways of joining them, like cold riveting, glueing, etc. Brass and the bronze I have is particularly malleable, and I've cold riveted this stuff successfully before.

The project is a secondary mirror holder, so the joints are small, and there really are no significant stresses that the joints will be subjected to. The number of joints are as few as 2, and as many as 4. And the temperature range the finished piece will be subjected can go from warm to sub zero as can be experienced with astronomy here in Oz.

Any help would be appreciated.

Mental.
