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?
According to metal reactivity series order table, aluminum has a better metallicity, but it will be passivated soon after contacting concentrated sulfuric acid, and won’t react again. But copper and concentrated sulfuric acid can react continually. So aluminum sheet becomes the positive pole after passivation.
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: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:As for graphite and aluminum sheet, which one has a better thermal conductivity?
Aluminum sheet has a better thermal conductivity, because metal is good conductor of heat, graphite is n't metal.
Q:what's the difference between zinc sheet and aluminum sheet?
Only zinc sheet can react, zinc is amphoteric.
Q:how to make aluminum products bright? How to polish or clean the products punch formed by 0.3mm aluminum sheet?
you can try to grind it with magnetic grinder.
Q:as for heating coil and aluminum sheet, which one is better for heating?
Both of them have advantage. It depends on the new product type it’s applied. Heating coil: it’s applied in some products with high temperature and large heat release, such as oven and other types.
Q:which is the best bonding method for aluminum sheet and plastic?
smear glue, there is a glue special for the bonding of plastic and steel materials.
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.
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.
