Melting aluminum
Just took off the aluminum siding on the front of my house. I don't know if
it's worth the gasoline to drive it to the scrap metal dealer. I probably have about 20 lbs. Is this siding aluminum suitable for melting and casting? Another question. My wife has three kilns. They go up to about 2000° F. Can I just simply snip up a bunch of siding, place it in a cast iron skillet and put it in one of her kilns? Just wondering. Ivan Vegvary |

Ivan Vegvary You are fighting physics. The ratio of surface area to volume of your siding is far too high and as you melt it, it will form a very large proportion of various aluminium oxides which will settle out as a thick layer of dross on the surface of your melt. Melting it commercially they would plunge it into an already molten pool of aluminium so as to exclude the air. I found all this out when I started casting a couple of decades ago and was re-cycling beer cans. Produced as much dross as aluminium. Now if you cut your siding into kiln sized pieces in a skillet, and filled the kiln with an inert gas you'd be fine ! AWEM |

AWEM Pretty much what Andrew said, although I'd add that the vessel in which you'd do the melting wouldn't be a good choice. Molten metals have considerable solvent power------and will dissolve other metals when well below their melting points. That principle is used in assaying, where molten lead, reduced from litharge, collects metals that melt at much higher temperatures (platinum, for example) and includes them in the button. Platinum melts well over 3,000 degrees F, yet it is dissolved nicely by the lead at a much lower temperature. If your objective were to reduce the aluminum for the sake of the exercise, a cast iron skillet would work, but you'd be contaminating the aluminum and altering its characteristics. You would end up with aluminum that is of poor quality. You'd also likely regret the stink and smoke that came from the finish on the siding. Extruded aluminum, or rolled aluminum doesn't cast as well as aluminum alloyed for the purpose. If your objective is to use the resulting metal for casting, you'd be far better served to re-melt existing castings, which are alloyed appropriately and flow much better. Right now, the scrap market is quite strong. If you have a recycling yard near, you might be pleasantly surprised to find your material is worth the trip. It's no retirement plan, but it should buy a nice lunch for you and the Mrs. Harold |

I have melted aluminum in sawed off propane torch cans (20 ga?) without any noticeable thinning of the steel. Bob It's a noticeable problem in aluminum diecasting, where the aluminum impinges on the steel with some pressure and cuts right through the oxide to the parent metal. Other than that, the process of dissolving iron in aluminum is pretty slow, although, as others have said, it quickly becomes enough to degrade the aluminum if you melt it in an iron or steel crucible. One useful solution is Dave Gingery's method of using crucibles made from "iron" pipe: he coated the inside with a thin wash of refractory clay and allowed it to dry before using the crucible to melt aluminum. Aluminum will dissolve in iron, and vice versa, even at temperatures far below the melting point of iron. The two metals can exist in a very wide range of solutions. -- Ed Huntress |

"Ed Huntress" fired this volley in
: It's a noticeable problem in aluminum diecasting, where the aluminum impinges on the steel with some pressure and cuts right through the oxide to the parent metal. It's not the high-temperature "corrosivity" of aluminum that's at issue. What happens is, iron oxide and aluminum enter into a Goldshmidt reaction -- that is, the combination is Thermite. This has the side effect of raising the interface temperature sharply, further increasing the solubility of the iron in the aluminum. Aluminum will dissolve in iron, and vice versa, even at temperatures far below the melting point of iron. The two metals can exist in a very wide range of solutions. Yup. The best miniature soldering irons have tips masked with aluminum plating to prevent any but the very tip to become tinned. LLoyd |

I have melted aluminum in sawed off propane torch cans (20 ga?) without any noticeable thinning of the steel." That seems to be consistent with results of aluminum melted via a rosebud acet heater in a crucible. This gets back to Harold's answer where he said (implied ? ) that aluminum melted without a sufficiently higher temperature than it's melting point would yield a great deal of dross. At least that is what I think he said. (Harold you want to jump back in here?) Bob (easily confused) Swinney That was Andrew, and it revolves around the huge surface area of thin objects, which readily oxidize to form aluminum oxide. Once formed, it is reduced only with an extremely high temperature, usually accomplished with an arc furnace. It's not materially different from the reduction of aluminum from ore, in other words.

Think how mercury reacts to form amalgams. That's an excellent opportunity to see it happen at ambient temperature. Harold |

I got married at 25 and yesterday marked 50 yrs with the same woman. Society just isn't the same any longer. Congratulations! I've got almost another twenty years to make it to that point, and since I married later, I will be 81 at that point.

Melting aluminum
One useful solution is Dave Gingery's method of using crucibles made from "iron" pipe: he coated the inside with a thin wash of refractory clay and allowed it to dry before using the crucible to melt aluminum. Ed Huntress This will work if you have to use a steel pipe crucible and is a good plan even with a cast iron pot. I discovered the solvent properties of molten aluminum back when I first started casting and decided to make a crucible from a length of 4" i.d. steel pipe with a 1/4" thick plate welded to the bottom. I fired it 4 times and a hole formed in the bottom. It was just a pinhole but it was enough to let aluminum flood the bottom of the furnace. Now I melt aluminum in a cast iron pot coated inside and outside with furnace cement from the hardware store thinned with water to a thick paint and brushed onto the warm metal. This lasts for 2 or 3 heats and can easily be renewed when neccessary. Mike |
