To be honest, unless you are a professional aluminum soldering iron with a lot of experience you probably will not have success with this product. Also, trying to solder something thinner than the rod itself will likely end badly. In order to be customer friendly, the supplier of that product must also recommend or provide a suitable flux for use with it. I've been soldering brass and torch/wire iron/steel for years and I can't seem to get it to work (even watching videos). Maybe it's just me, maybe a flux and/or alloy, but this product isn't for everyone, even if you're talented.
