Regular solder does not stick to aluminum at all, making it extremely difficult to solder. However, there is a way that allows you to do this in literally half a minute. Moreover, this does not require soldering skills at all; absolutely anyone can do everything with an ordinary camping torch.

Aluminum soldering process
Before starting work, you need to warm up the aluminum part for soldering for 10-15 seconds, or a little more if it is massive.
When it warms up, apply a stick of Castolin 192 FBK solder to it. It should melt from the hot part, but at the same time we additionally heat its edges with a burner.
Use a solder stick to evenly apply the wire over the soldering area, periodically removing the torch to avoid melting excess. Castolin has a flux that breaks down the aluminum oxide film so everything sticks right away.
