Super Alloy 1 Multi-Metal Solder



These pics come from a new aerospace test facility that they are constructing at the University of Notre Dame. The SSF-6 is working great.


welding stainless steel

I am attempting to make all of these fittings air tight as they are used for pressure measurements. We can¹t have any leaks. I had very little warpage of my base metal and I think this is really going to work out very well.

The 350º Pot Metal/White Metal/Zinc Die Cast Solder

Super Alloy 1 is a white metal solder that joins all white metals including pot metal, zinc die cast, lead, and aluminum. Its unique properties can also join any of these to practically any other metal—bronze, steel, copper, or brass. The rod also lets you join metals such as steel to aluminum, which some welding instructors are still claiming can't be done.  


Unique Characteristics:

  • The low temperature solder has a working temperature of 350°F for preventing warpage and base metal damage
  • Can be used to join aluminum with a soldering iron
  • Rod and flux work synergistically to prevent oxidation during soldering.
  • Super Alloy 1 flux is completely non-corrosive and washes off with warm water

Joining Dissimilar Metals

There are various applications in which repairs are made from materials with different compositions. Conditions like these bring about the need for soldering different metals, which can be effectively done by using a product such as Super Alloy 1.


An effective repair between dissimilar metals is that which is as durable as the weaker of the two metals being joined. Using a low temperature solder, the repair can possess enough tensile strength and ductility so that joints don’t fail later on. Such repairs, especially those done on white metals such as aluminum, stainless steel, and zinc die cast, can be accomplished using a white metal solder and specific welding processes. 


Note:  Super Alloy 1 cannot be used for aluminum boat repair, large masses of aluminum, or thick aluminum.  Please use Super Alloy 5 and an oxyacetylene torch for these applications.
