Q:How to press multilayer aluminum sheets (aluminum sheet's thickness: 0.2mm) together and keep them inseperate after pressing?
resistance welding usually overlays two pieces together and presses them, heating them to melting state through current, you can try multiple sheets.
Q:How to solve the loose bonding of aluminum sheet and silica gel?
Bonding silicone rubber needs surface treatment, after using silicone rubber surface treating agent of Kuer , you can bond them with 4211 adhesive.
Q:what's the size of aluminum sheet circle?
Aluminum sheet circle’s size is usually the width of coil stock (mm) : 500-1250,800-1400,1000-1600, thickness of coil stock (mm) : 0.4-3.0,1.0-6.0, weight of coil stock (kg) : 8000,10000, diameter of blank(mm) : 85-660,85-750,100-900. Aluminum sheet circle is broadly used in electron, daily chemical industry, medicine, education and car accessories industry. Electrical appliance, thermal insulation, machine manufacturing, cars, spaceflight, military industry, mould, construction, printing and other industries. Kitchenware, such as non-stick pan, pressure cooker, etc. and hardware, such as lampshade, shell of water heater, etc. they are one of the highly processed aluminum products with largest consumption.
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 clean the aluminium oxide on the surface of aluminum? What kind of materials should we use to clean the thin aluminum sheet, and what's the concentration?
You can sprinkle the mix of Alkaline water,vinegar,washing powder and liquid detergent on the surface. And after a period of time, rub it with soft silk, after it being dry,sprinkle again and rub until it's clean.
Q:does aluminum sheet need to conduct ROHS detection?it's metel material, how much detections should it conduct for ROHS detection?
it needs 4 CTI detections for ROHS.
Q:Could two pieces of aluminum sheets be welded together?
sure, it does.
Q:what's the temperature tolerance of aluminum sheets?
aluminum is a kind of silver white metal,melting point:660.4℃, boiling point: 2467℃,density: 2.70 g/cm³,very light, about 1/4 of iron's has low hardness and good ductility, which makes it suitable for being pulled into threadlets or pressed into aluminum foils, and the later is usually used for packaging candy and cigarette. it has good electrical and temperature conductivity. it's used for the manufacture of electric wire and cable in electric power industry, and for the manufacture of cooker in daily life.combined with the magnesium , copper,zinc,tin,manganese,chromium,zirconium,silicon and other elments,it can formulate various alloys that is broadly used for the manufacture of airplane,car,ship, materials of daily living equipment and the doors and windows of construction industry.aluminum is one of the best reflectors of heat and light, so it is used as thermal insulation material and the manufacture of reflecting mirror in the reflecting telescope.
Q:How to polish aluminum sheet to be bright?
you must do some protection work, or you will fail once aluminum contacts air. Aluminum sheet is easy to be oxided and volatilized.
Q:does aluminum sheet has a function of magnetism isolating?
