- Q:how to avoid oxidation of aluminum sheet after wire drawing?
- leave it alone after wire drawing!aluminum sheet will formulate a layer of dense oxide film. So you don't need to worry about it! Don't often polish the aluminum wire, or they will be more and more slimsy, the oxide film is used for avoiding reoxidation.
- Q:Which kind of glue is best for bonding aluminum sheets?
- 502 or universal glue
- Q:why can't aluminum sheet burn after polishing?
- because aluminum will rapidly formulate dense oxide film once being exposed in air, oxide film will generate after polishing, it can't burn.
- Q:As for cast aluminum sheet or wrought one, which one has faster heat conduction?
- 1,duralumin: it's the alloy of aluminum, copper, magnesium, manganese and other metals. it's suitable for compacting by rolling, and it has a higher strength and hardness than common aluminum products. 2, aluminum: it contains many inpurities, is crisp and easy to be smashed.cast aluminum usually is secondary aluminum, and it is produced by remelting the collected old aluminum pots and spoons.3, wrought aluminum: it contains 98% aluminum and 2% or more inpurities, and is comparatively pure aluminum. its soft priority makes it suitable for being pressed into various shapes, aluminum pots,aluminum lunch box,aluminum sheets,aluminum wires,aluminum pipes are all made by wrought aluminum.you will know their defferences from their definition.
- Q:which kind of aluminum sheet could be bended after being etched?

- Q:why does the bubble apear a few minutes later after putting aluminum sheet into dilute sulphuric acid?
- Because there is oxide on the surface of aluminum, the reaction will be quicker after polishing the oxide with abrasive paper.
