Q:what's the size of gap while pressing 6mm aluminum sheet?
unilaterial gap is 0.1-0.15mm, and you can change the gap according to cutting effect.
Q:could aluminum sheet be attracted by magnet?
no, it couldn't.
Q:Who knows the ceiling size of aluminum hang-parcel?
General size of aluminum hang-parcel: 100mm、150mm、200mm、250mm, you can order the length according to your actual demands. General color of aluminum hang-parcel: white, black, blue, pearl white, bianco canopus, etc. you can order the color according to your actual demands. General thickness of aluminum hang-parcel: 0.4mm、0.5、0.6、0.7、0.8mm, you can order the thickness according to your actual demands.
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: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 ring-pull can be transformed as aluminum sheet?
Q:Could induction heating fuenace be packaged with aluminum foil as insulation material?
It’s useless. Aluminum foil will generate eddy and emit heat after medium induction, which will reduce the thermal efficiency of medium frequency. Now I provide a method for reference only. Induction coil will be water cooling and is packaged by thermal cement and other materials. Use asbestos sheet and other materials to transform the both ends of induction heating coil as baffle which is mobile and convenient for load and unload. When steel tube is heated in the induction coil, you can put down the baffle to prevent large loss of heat, shorten heat time and improve heat efficiency. When the seamless steel tube is heated into setting temperature, you can open the baffle to conduct expanding process, and you don’t need to think about the thermorytic problem of steel tube in the expanding process. It’s important to shorten the time of expanding process. Baffle is used for heat retaining of medium frequency heating and extrusion forming in our factory. The method above for reference only.
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 will happen when aluminum sheet is put into copper chloride solution?
the chemical equation of the reaction, 2Al+3CuCl2=2AlCl3+3Cu, the phenomena when aluminum sheet is put into copper chloride solution: there is red solid generating on the surface of aluminum sheet.
Q:what’s the difference of activated aluminum and aluminum sheet?
39,the thermal treatment of age hardening aluminum alloy, 40, lanthanum-praseodymium-cerium aluminum alloy and its producing technology, 41,casting method of cool room pack alloy without draft angle, 42, use the anti-corrosion alloy layer to protect the surface of nickel base alloy products, 43,saltless and inoxidizability remelting method of aluminum, aluminum alloy and aluminum waste...
