- Q: I take an extracurricular aircraft class, and I got the okay to take some old painted sheet aluminum for another project I'm working on. The problem is, what I'm using it for I need bare aluminum. I heard around that air crafts are painted with something that regular (store-bought) paint stripper can't remove. Is this true? I am aware of the fact that stripping something like that will result in a toxic paint sludge, so I've taken precautions for that. I just need to know if heavy-duty paint stripper from Home Depot will do the job. Thanks :)
- It depends on how old the paint is. If your panel was painted before the 1970's, then pretty much any chemical paint stripper will work. After the 70's, they started using epoxy based primers and paints and those are more resistant to chemical strippers. In any case, wear rubber gloves and breathing protection while using chemical paint strippers. They can burn your skin and create toxic fumes when in use.
- Q: I have been trying to make some thermite for a while now, and I haven't had much success. I have tried using iron oxide and that didn't work. then I tried using manganese dioxide, also without success. I'm pretty sure I have the right proportions for each of the corresponding oxides, but it just isn't working. I am using magnesium ribbon to light it.The aluminum I am using is the byproduct of me trying to cut a block of aluminum with a hacksaw (best way I have available to cut it) and there is a lot of aluminum powder that is being made. But i'm not sure if it is fine enough to be effective. I don't have an etch-a -sketch so that's not an option. I know that it has to be fairly fine grained, but how small do the particles need to be?FOR EVERYONE WHO IS GOING TO TRY AND TELL ME THAT MAKING THERMITE IS DANGEROUS OR SOMETHING ALONG THOSE LINES......DONT!!!!!!!!.......... IM NOT GOING TO LISTEN SO SAVE YOURSELF THE TYPING AND ME THE READING
- In 35+ years of demonstrating the thermite reaction, I have used fine aluminium powder to quite visible small bits. The proportions don't seem too critical, but try and keep near the amounts represented by the balanced eqtn. The difficult bit is getting the wretched stuff to ignite. With some mixes several strands of magnesium ribbon as fuse still wouldn't get it to ignite. I found a pile of 'ignition powder' at the base of the Mg often helped. There was a good commercial one available in the UK but I often made one up, main ingredients barium peroxide and magnesium powder, about 50/50. Needless to say, ignite with this mix where you won't breathe any nasty fumes. To get a good result, if I didn't use a proper crucible, I shaped one of Al foil about the capacity of 2-3 eggcups. This was put on sand in a big coffee tin, then more sand added to fill round the sides. This would give a good amount of iron. I once made the mistake of rushing in too quickly to get out the red hot iron.... and completely melted the ends of a large pair of Nickel tongs!
- Q: What are the different joining methods for aluminum coils?
- Depending on the specific application and desired bond strength, there are multiple methods available for joining aluminum coils. Some commonly used techniques include: 1. Welding: TIG welding, MIG welding, and laser welding are all viable options for welding aluminum coils. These methods create a robust and long-lasting bond that ensures structural integrity. 2. Brazing: By melting a copper-based alloy filler material, two aluminum coils can be joined together. Brazing is particularly useful for joining thin aluminum coils and provides a strong and leak-proof connection. 3. Adhesive bonding: This non-destructive method involves using a high-strength adhesive to bond the aluminum coils. Adhesive bonding is often preferred for applications where aesthetics and surface finish are vital, as it does not leave any visible welding or brazing marks. 4. Mechanical joining: Techniques such as riveting, clinching, and using fasteners like screws or bolts are categorized under mechanical joining. These methods offer a reliable and easily reversible bond, making them suitable for applications that require disassembly. 5. Roll bonding: Roll bonding is a process that involves passing two or more aluminum coils through a rolling mill under high pressure, resulting in the creation of a single composite coil. This method is commonly employed for joining dissimilar metals or creating laminated structures with different alloy combinations. Each joining method has its own advantages and limitations, and the choice depends on factors such as desired strength, cost, production volume, and specific application requirements. It is crucial to carefully consider these factors to ensure the most appropriate method is selected for aluminum coil applications.
