Q:what kind of aluminum sheet is suitable for aluminum alloy double-edged saw?
general horizontal driving sawing and precision sawing.
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:Which kind of glue can bond two pieces of aluminum sheets?
you can use jellied universal glue, don't use the liquid one, because it's only suitable for plastics or materials easy for erosion.
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: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: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:what's the difference between zinc sheet and aluminum sheet?
Only the zinc sheet reacts after adding concentrated nitric acid in drops ,zinc is amphoteric.
Q:what's the difference between the knocking voice of aluminum sheet and stainless steel?
The voice of aluminum sheet is toneless, and the voice of stanless steel is more crisp.
Q:which kind of abraser should be used for deburring of aluminum sheet?
you can use soft resin grinding stone.
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.
