The 75 ohm cable is fine for usage. There are several minor problems

There was a guy at the Fort Tuthill hamfest who was
soldering aluminum. Has anyone ever tried his technique
on aluminum coax? I still have some of that aluminum
solder.

Has been my lot that the "solder" is the least important part (got 60/40

Aluminum has the nasty habit of oxidizing almost immediately on
cleaning/brightening. I have had some luck by using a silicone oil/lub
on the braid and scrubbing/sanding the braid clean and then soldering.

Your milage may vary ...
