Q:which kind of aluminum sheet could be bended after being etched?
general etching materials include stainless steel and copper.
Q:could aluminum sheet be attracted by magnet?
no, it couldn't.
Q:why is copper sheet but not aluminum sheet that becomes the negative pole after putting copper sheet and aluminum sheet connected with wire into concentrated nitric acid?
it may be that aluminum won't react with concentrated nitric acid.
Q:Which kind of solution should I use while welding aluminum sheet and copper pipe by tin soldering?
1, you must use over 350W soldering iron, 2,prepare some borax and tin soldering paster, you can’t use rosin to weld it, 3, polish the pipe to clean with fine abrasive paper and borax, 4, put the pipe and sheet into borax, use the soldering trip to rub on the weldment with some borax. 5, after the pipe and sheet become hot, use the soldering iron with the paster and tin to rub the pipe and sheet in borax, then it can be welded. 6, they can be welded together after welding.
Q:Could two pieces of aluminum sheets be welded together?
youcan use aluminium soldering,what do you want to weld?
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.
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 will know their defferences from their definition.
Q:after putting aluminum sheet into the area between magnet and iron products, could magnet attract iron again?
magnet can attract iron if the aluminum sheet isn't too thick. Because aluminum can't cut off magnetic line of force, unless aluminum sheet's thickness surpass the range of magnetic attraction.
Q:How to polish aluminum sheet to be bright?
you can try mirror polishing agent.
Q:has aluminum sheet reacted with concentrated sulfuric acid?
it can be regarded as no reaction, concentrated sulfuric acid will make aluminum's surface inactivation,and produce a layer of dense aluminium oxide film which will prevent further reaction.
