2. Application of Coated Aluminum Sheet Coil For Roofing And Cladding System

Building, curtain wall, ceiling, panels, food packaging, condenser, air filter, refrigerators, washing machines, solar energy, automobile manufacturing, ship manufacturing, machinery manufacturing, electric equipment such as cosmetic packaging, machinery manufacturing industry, can also be used in power plants, chemical anti-corrosion insulation in petrochemical industry, etc.  


3. Feature of Coated Aluminum Sheet Coil For Roofing And Cladding System

*Such coil is specially designed to replace aluminum ingot, due to the high export tax of aluminum ingot, the coil has better price than ingot.

*This type of coil can fit customer's remelting furnace just like ingot, no need to make any change to the production line that was previously used for ingot. The standard coil size and weight is very suitable for the feed gate of furnace.

*This type of coil causes less material wastage than ingot when remelted.

*Our coil is made directly from ore, no need to go though the ingot making process, quality is much better than other suppliers who use ingot scrap to make coil.

Be free from Oil Stain, Dent, Inclusion, Scratches, Stain, Oxide Dicoloration, Breaks, Corrosion, Roll Marks, Dirt Streaks and other defect which will interfere with use

Q:how much should the current be adjusted when I use pulse aluminum welding machine to weld 0.7 aluminum sheet?
60-70A current is enough for 0.7 aluminum sheet,the key poiny is that the thin sheet should be bonded with iron sheet or other assistant cooling device when you weld it, or it will be burned through.
Q:could aluminum sheet be attracted by magnet?
no, it couldn't.
Q:why can aluminum sheet after oxide film removal react quicker with hydrochloric acid?
the reason is very simple, the original aluminum sheet has a layer of dense oxide film AI2O3, which has prevented the inner aluminum sheet from reacting with hydrochloric acid. but after oxide film removal, aluminum sheet will directly contact hydrochloric acid, generating H2.
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:Could copper wire be welded with aluminum sheet?
Copper wire could be welded with aluminum sheet, and it needs to use low temperature welding method, if copper wire is in the unit of millimeter and aluminum sheet is also in the unit below 1 mm, you can use electric soldering iron to heat it as hybrid welding and choose low temperature welding materials, you can use WEWELDING M51 welding wire and M51-F flux to complete welding. As for the large aluminum sheet, you can take liquefied gas multihole lance as heat source, then choose the same low temperature materials as welding materials, you can use WEWELDING M51 welding wire and M51-F flux to complete welding. Welding fundamentals of these two welding methods: both of them are use heatable heat source to heat the matrix to 179 degree, the melting point of WEWELDING M51, then use matrix’s heat conduction to melt welding wire, completing welding. The process of melting welding wire is the process of smearing the welding wire with flux into welding area, melting welding wire completely depends on matrix’s heat conduction.
Q:why does 10% sulfuric acid not react with aluminum sheet?
10% sulfuric acid has a high concentration and will be passivated and formulate a layer of oxide film after reacting with aluminum,and the reaction will stop after seperating sulfuric acid and aluminum. there is a layer of Al2O3 oxide film on the surface of aluminum, so it's hard for sulfuric acid to break the oxide film and react with aluminum.
Q:how to produce aluminium sheet circle?
As for the process, you can use punch.. as for professional machines, for example, stationary press in open type, mechanical press/ single-point press. The material you say is neither big nor small, blanking…(cutting them into sheet circle you want) you can add an uncoiling if it’s coil stock: open-type inclinable press, four-point press,ect. It’s not certainly accurate) punch, oil press, double , four-column hydraulic (oil) press,etc. it needs about 315T,(estimated value, closed type single, blank material cutting (cutting into square ) 2, it contains sheet metal forming technology, crank press: 1: straight side two : 1, but the components you said is simple, only two steps.
Q:does aluminum sheet has a function of magnetism isolating?
copper sheet is better.
Q:which kind of abraser should be used for deburring of aluminum sheet?
you can use soft resin grinding stone.
Q:how to process 0.3mm hole on aluminum material?
It's bored by drill.
