You can't weld steel to aluminum, just bolt/rivet/glue. You're talking about a dissimilar metals reaction, which can be a real problem. The e-brake levers in the 60 and 80 series (not sure about the 100) are aluminum with a metal pin holding them in place, very common for corrosive issues and binding up. So, you'd have to really coat one of the metals or both (paint or powder coat) to prevent this from happening.
