Galvanic corrosion between brass component and aluminum conductor
We manufacture terminal blocks. I have a brass contact wherein aluminum conductor/ wire shall be tightened using brass (CuZn37) screws. Will galvanic corrosion occur between brass and aluminum. Will tin plating on brass prevent galvanic corrosion?
It depends. If the Aluminium parts are much larger than the screws then it may take a long time for the corrosion to spread; but if the parts are evenly sized then it may be sooner. Yes, tin or zinc will reduce the speed of galvanic corrosion.

I have to replace all my brake lines. They don't sell them any more for my car. It's going to be very difficult with all the bends and turns. I thought I could use aluminum tubing and maybe some would short connected with a brass fitting.
How long do you think this will last before it's corroded enough be on use?

Aluminum is not legal to use for brake lines. it will not stand the needed pressure.
