Thank Durafix a zinc-based alloy and other materials, have managed to repair a bike aluminum BH we had forgotten in the attic for having a broken rear frame.
Welding aluminum is very complicated, or at least it was until I tried to use Durafix; No welding aluminum and I can stand. The welds are stronger than aluminum itself, and instead the material melts before I do the base (aluminum) material, so that we can "work it" with some tool.
Moreover it serves to weld many types of materials, such as brass, bronze, copper, non-ferrous etc.
