can I solder a spade connector to copper wire?

I have a large copper wire that goes from my battery to my voltage regulator (72 VW). It requires a spade connector, and all I can find is aluminum. The crimps tend to come loose after a while. Can I solder the stranded copper wire inside the spade connector? Thanks.

Might be hard to solder large gauge to aluminum depending on how big it really is. That spade connector might not really be aluminum, it could be pre-tinned.

Might want to try a trick I learned. Use a piece of copper pipe of the correct size (I used 1/2 for a battery-starter connection), pound one section flat with a hammer and anvil or a vise. Cut the size slot you need for the connection, then solder the wire in with a torch after crimping.

Worked for me....
