Super Alloy 1 multi-metal solder can be used to join dis-similar metals. In this video, aluminum is joined to stainless steel, using a propane torch. This same technique can be used to join many metals, in any combination:
- pot metal
- zinc die cast
- stainless steel
Previously, joining these two metals was unheard of in the welding community. Super Alloy 1, the 350 degree solder, makes easy work of this seemingly impossible of application.
This multi-metal solder is paired with a unique flux that works as a temperature guide, turning brown at the proper working temperature, and indicating when to add the Super Alloy 1 rod.
Tip: Indirect heating is very important when using this duo.
While almost any torch system can be used, we recommend larger torch tips to broadly heat the work piece. Oxyacetylene can be used with the oxygen turned low. A heat gun can also be used with this low temp solder.
