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:what's the size of gap while pressing 6mm aluminum sheet?
choose the 8-10% of the thickness for two-sided gaps.
Q:How to clean the aluminium oxide on the surface of aluminum? What kind of materials should we use to clean the thin aluminum sheet, and what's the concentration?
you can answer sodium hydroxide solution, dilute acid is useless, aluminum's oxide film is very thick,as for concentration, aluminum will be passivating in concentrated sulfuric acid. if you are high school student,higher concentration is better, you can complete deoxidation by abrasive paper.
Q:why does the hardness of 2024 aluminum sheet not increase but decrease after thermal treatment?
The hardness of 2024 aluminum sheet will decrease after thermal treatment(solution treatment), and it will increase after aging treatment.
Q:what’s the difference of activated aluminum and aluminum sheet?
you can use weak acid ,weak base solvent or steam to clean the oil and dirt on the surface, it's activated aluminum, their difference is that activated aluminum has porous structure oxide film.
Q:could magnet attract iron with the seperation of rubber and aluminum sheets?
it does within the range of magnetic force.
Q:whst should I notice while welding aluminum sheet and aluminum block?
two types of aluminum reach melting points, aluminum block must be preheated when you weld them with small current, you will know how to do it. You can use argon-arc welding back and forth, preheat it with small current.
Q:could aluminum sheet be attracted by magnet?
no, it couldn't.
Q:is general aluminum sheet fire-proof?
aluminum products has low melting point and is nonfireproof,and aluminum alloys will be better.
