Super Alloy 1 is a low-temperature multi-metal and pot metal solder that bonds all white metals. It can also join white metals to practically any other metal–even ferrous to non-ferrous metals, making it an effective solder for aluminum to steel repairs.
Many solders require high heat, which can damage or warp the base metals, but Super Alloy 1 is a premier low-temperature solder that bonds metals at half the melting point of pot metal. Its unique honey flux turns root beer brown when the base metal has reached the 350°F working temperature, enabling quick and easy soldering repairs with little or no preheating. This all-position rod is ideal for repairing pot metal pitting and building up worn or broken areas.
You can apply it with any heat source, including a soldering gun, heat gun, or propane torch, with no welding expertise required. Its user-friendliness and versatility make it a popular choice among DIY enthusiasts and hobbyists who need to perform quick repairs or tackle small projects, especially on their vehicles. Super Alloy 1 is the industry standard for classic car restoration and antique auto applications. This reliable, low-temperature solder has salvaged thousands of priceless classic car parts, from pitted pot metal grilles and emblems to cracked aluminum housings. Restorers trust Super Alloy 1 to create durable, high-strength repairs that they can then plate or paint to match the original finish. This process preserves the value and integrity of these vintage pieces.
Why Choose Super Alloy 1
Pot metal is notoriously difficult to work with: it melts easily, oxidizes quickly, and resists most traditional solders. Super Alloy 1 solves all those problems, allowing you to repair, rebuild, and restore your parts while keeping them completely original.
Keeps Parts Original — no fillers or shortcuts; restores real metal.
True Metal-to-Metal Bond — the repair becomes part of the original surface.
Low 350°F Working Temperature — protects delicate details.
Bonds Dissimilar Metals — pot metal, zinc, brass, copper, steel, pewter, galvanized metal, Zamak, and more.
Flux Temperature Guide — turns root-beer brown at the perfect soldering temperature.
Easy Clean-Up —flux washes off easily with warm water and a wire brush.
Can be plated, painted, powder-coated, shaped, polished, or machined.
Applies with any Heat Source — propane, MAPP, butane, oxyacetylene, or heat gun.

Shelf Life and Storage
Store rods in a dry, sealed container, away from extreme temperatures and humidity, to retain their effectiveness for years. Super Alloy 1 flux maintains its consistency and performance for two years when stored tightly sealed in a cool, dry environment below 77°F (25°C).
How to Use Super Alloy 1
Prepare Metal with sandpaper, emery cloth, or a wire brush. Remove all oxidation.
Apply Flux directly to the repair area. Dip the rod in the flux and apply directly to the parent metal.
Heat Base Metal, Not the Rod. Keep the torch 4–6 inches away and move the flame continuously to avoid overheating.
Watch the Flux — it bubbles and turns light brown at 350°F. That’s your cue to apply the rod.
Apply Rod. Drag the rod across the joint until it flows smoothly; remove heat immediately once it flows.
Cool Naturally; never quench in water.
Remove Flux with warm water and a wire brush
Tip: Bevel (“V-out”) cracks or pits before soldering for maximum strength and a smoother finish. For larger workpieces, lightly preheat the rod tip after heating the base metal to help flow evenly.

What Our Customers Say About Super Alloy 1
I would have bet this was a waste of money. Boy, was I wrong! The fan on my antique car hit the radiator when the one lower mount bolt fell out. It just hit 10 of the tubes slightly. Your Super Alloy 1 fixed the tubes without much difficulty. It did take a little learning experience, but I couldn’t be happier. It saved me a $450.00 custom-made aluminum radiator. — Barry Seel
In 40+ years as a jewelry repairman, pewter repair has always been considered “impossible” but the repair was fairly easy with the Super Alloy 1. Heat control was very important as the tankard lid was very thin, but in the end the repair was strong & serviceable. A quick touch-up with artist paint matched the old oxidized color of the lid & the customer was very happy. Thanks for an excellent product & the online videos were very informative and helpful. — David Weinstein, The Jewel Shop, Huntsville, AL
Just completed my first job with Super Alloy 1 on pot metal and it worked GREAT !!!!! After I filed it down and smoothed it out with emery cloth, my customers could not tell where the crack was originally. I would be more than willing to endorse your excellent product !!!! –Gerald Selden, President, Regloh, Inc
Chrome and Plating Instructions
Super Alloy 1 repairs can be polished or chrome-plated for a flawless finish. Be sure to remove old chrome prior to soldering, using a dip-and-strip process. Before plating, ask your plater to apply a slow copper charge beneath the nickel and chrome.
Frequently Asked Questions
What makes Super Alloy 1 better than Bondo or epoxy?
Unlike fillers, Super Alloy 1 restores the original metal — forming a permanent metal-to-metal bond instead of a patch.
Which torch should I use?
Super Alloy 1 works with propane, MAPP, butane, acetylene, or oxyacetylene torches — choose the right one for your project size and thickness.
Can I use Super Alloy 1 on aluminum?
Super Alloy 1 is designed for pot metal, zinc die-cast, brass, steel, copper, galvanized metal, and similar alloys. It is not recommended for aluminum boats, cast aluminum, diamond-plate aluminum, or heavy aluminum pieces. For those, use Super Alloy 5 with an oxyacetylene torch.
What is the remelt point of Super Alloy 1?
The remelt temperature is approximately 450 °F (232 °C). Avoid reheating above this once your repair is complete, or apply Heat Freeze Heat Paste to protect against remelt.
I purchased aluminum rods that were demonstrated on pop/beer cans at the fair and they didn’t work when I took them home. Is this the same rod?
If you saw a live “pop can” demonstration at a fair or trade show, please note that those rods are not Muggy Weld products. They’re often imitations that look similar but are made with inferior materials and don’t deliver the same results.
Summary
