Cold Rolled Stucco Embossed Aluminium Checker Plate 5 Bars


According to the composition of alloy, it can be divided into 5 items.

1)    High purity aluminum plate (rolling by the content above 99.9 high purity aluminum)

2)    Pure aluminum plate (rolled by pure aluminum)

3)    Alloy aluminum plate (composition of aluminum and other alloy material, usually alu-copper, alu-manganese, alu-silicon, alu-magnesium, and so on)

4)    Composite aluminum plate or brazing plate (made by a variety of composite materials)

5)    Alclad aluminum (coated aluminium sheet outside of aluminium sheet used for special purposes)

 According to the thickness, it can be divided into 4 items.

1)    Thin plate (aluminum sheet) 0.15-2.0mm

2)    The conventional plate (aluminum sheet) 2.0-6.0mm

3)    Medium plate (aluminum plate) 6.0-25.0mm

4)    Thick plate (aluminum plate) 25-200mm

5)    More than 200 super- thick plate

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:why does the bubble apear a few minutes later after putting aluminum sheet into diluted hydrochloric acid?
Aluminum element is extremely activated and will react with oxygen, generating aluminum oxide, once being exposed in air, so there is a layer of aluminum oxide on the surface of daily aluminum products including aluminum sheet. When aluminum sheet is put into diluted hydrochloric acid, aluminum oxide on the surface will firstly react with hydrochloric acid, generating aluminium chloride and water, the process won’t generate bubble, but after finishing the reaction of aluminum oxide on the surface, when the exposed aluminum element reacts with hydrochloric acid, generating aluminium chloride and oxygen, the bubble appears.
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:why could aluminum pot be repaired by knocking the aluminum sheet into the pot but not being bonded by glue?
the oxidation rate of aluminum's surface is very quick, so we cann't use the method of tin welding, and the cost of argon arc welding is very high,so aluminum pot's repair usually uses riveting. aluminum has low hardness and good ductility, so it can be repaired by tightly knocking, without the bonding of glue. general glue will decomposed in open fire, if we bond pot by glue, the pot after repair won't be able to endure high temperature.
Q:As for graphite and aluminum sheet, which one has a better thermal conductivity?
aluminum sheet
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 enterprises are aluminium sheet circles used in?
user use cold squezz method to transform the aluminum sheet circle into various standard capacitor shell, aluminium collapsible tube shell, which are broadly used in electron industry, daily chemical industry, medicine, education and automobile products,electrical appliance, heat preservation, machine manufacturing, automobile,spaceflight,military industry,mould, construction, printing and other industries.
Q:can the oxide film on the surface of aluminum sheet prevent the erosion of acid liquid? Why?
yes, acid can react with aluminum oxide , generating salt and water, but its anti-corrosion will be stronger if oxide film on the surface is enough dense.
Q:what kind of aluminum sheet is suitable for aluminum alloy double-edged saw?
saw web size depends on the thickness and height of sectional material,equipment compatibility and permitted installed saw web size .
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.
