Q:Aluminium plate A1100P is equivalent to GB, what model?
1, aluminum plate A1100P equivalent to national standard AL1100 aluminum plate.2 and 1100 are pure aluminium, the content of aluminium is 99%, which can not be improved by heat treatment. With high corrosion resistance, electrical conductivity and thermal conductivity, and its small density, good plasticity, through pressure processing can produce all kinds of aluminum, but the strength is low. Other process properties are basically the same as those of 1050A. 1100 commonly used to have good machining performance, high corrosion resistance, high strength does not need not see, such as video and chemical handling and storage equipment, sheet metal products, hardware, hollow spinning drawing goods welding key combination, reflector, nameplate.
Q:Would you please tell me what putty to use on the aluminium board, what kind of putty, and the painting process?
Applied atomic ash.Consider adding an interface agent, that is, applying an interfacial agent on the aluminum plate, and then applying a topcoat on the interface agent after drying.
Q:polish aluminum on my motorcycle?
Q:Why should we recycle aluminium?
Aluminum has to be extracted from the earth which is costly and takes a lot of energy. Then the aluminum needs to be smelted out of the rock that it is in, again this takes a lot of energy and creates toxins. Aluminum like all metals are finite, we conserve resources and the land where they will need to be extracted by recycling it.
Q:I have a number of existing 4mm aluminum plate,
5052, aluminum stamping bending will not break it.
Q:Aluminum vs. steel shoes for H/J?
Like others have pointed out aluminum are lighter but more expensive and must be replaced more often, but they are also much lighter. When I am seriously competing I put aluminum shoes on my horses just for the summer show season to take advantage of the lighter weight, then back to steel for the rest of the year (and with steel being as durable as it is I can keep the same pair stored away to be put back on in the fall.) It's your call, its not a HUGE difference but it might help him pick his feet up better.
Q:Why does deodorent have aluminum in it?
Well, I'm looking at my deodorant now, it looks like aluminum zirconium tetrachlorohydrex is the active ingredient, the actual anti perspirant part. This is probably why it is a bad idea to eat it.
Q:Why is aluminum conductive if alumina is an electrical insulator?
Corroded aluminum is not the same substance as rust is not the same as iron. Iron is simply Fe, rust is Fe2O3 if I am correct. So the alumina is not the same as aluminum. Just because something has an element in it doesn't mean it has the properties of the material, or is even similar to that element in anyway. Glass is conductive when its molten, but not when its cool and hard, like windows. So unless what you are dealing with is exactly the same thing, you can't assume anything about it, generally. EDIT: Aluminum is Al, alumina is Al2O3. Alumina is an oxide, aluminum is a pure element, they aren't the same so they can have different properties. As for being an insulator, the layer of alumina is usually so thin it only adds a small amount of resistance to a circuit. If you had a block made of pure alumina and you tried to run current through it it would add lots of resistance or so much there would be virtually no flow.
Q:which is the right machine for aluminum welding,,,tig? , mig? or what?
It all depends on what you are doing. For light duty stuff 1/8 to 1/4 inch a spool gun will be the cheapest option. For intricate work tig. For production a push pull unit with a pulse arc but these are big $.
Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
it's metal and belongs to hardware
