Anyone have experience with Alumiweld?

Does anyone have experience with a material called Alumiweld? It's material in a rod form, that supposedly you can use to join metals together by melting it with a torch. Apparently the joints are stronger than aluminum and mild steel, so not as strong as a weld, but strong enough perhaps for light to medium duty applications.
