I use paste flux from Home Depot to solder Cu clad Al. none of my 50 year old soldered to tin plated aluminum work has corroded yet. Have had excellent results with soldering duplex Cu Al. Just as easy as soldering new copper. A blip covers the exposed cut end of the wire just like a solid copper wire. I was shocked to find it was this easy. Use the paste flux and grin. The corrosion thing on non SMD to me is like campfire stories of Sasquatch. Many decades of soldering 18-20 AWG do not lie. Now the liquid acid is Mr Hyde personified. I was forced to use it once on an old International Harvester bulldozer with a 3/0 cable that traveled inside track channels to Nightmare, Nebraska. It worked but neutralizing it was a chore.
