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:how to connect copper pipe and aluminum sheet?
it depends on the size and requirement, we can use ultrasonic wave rolling welding to connect copper pipe and aluminum sheet.for example, solar energy radiator-fan contains connection of copper pipe and copper sheet, ultrasonic wave rolling welding equipment is used here.ultrasonic wave welding of metals is suitable for the welding of copper to copper, copper to aluminum and aluminum to aluminum.
Q:What does exterior wall imitate aluminium paint have? Imitate aluminium plate paint is fluorocarbon paint?
The exterior walls are painted with aluminium and plastic panels, and only fluorocarbon metal paint is used. The fluorine content determines the service life;The construction technology of fluorocarbon metal paint is relatively complex, and the price is more expensive, generally including the construction is roughly equivalent to more than half the price point to use aluminum plate;
Q:What are the aluminum plates for?
The products are widely used in construction, curtain wall, packaging, food, air conditioners, refrigerators, solar energy, automobile manufacturing, ship manufacturing, machinery manufacturing, cosmetics packaging and other electrical appliances, machinery manufacturing industry, can also be used in power plants, chemical and petrochemical industry factory anticorrosion & insulation etc..Shandong Pingyin Hengshun Aluminium Co., Ltd. specializing in the production of (hot rolling, cold rolling aluminum alloy) roll. Aluminum coil. Alloy aluminum. Aluminum. Ultra wide / ultra thick aluminium alloy. Sawing, shearing customer requirements specification aluminum alloy thick aluminum wire, aluminum, aluminum flange with aluminum, power plant / chemical anticorrosion and insulation alloy factory aluminum moisture-proof aluminum roll roll.
Q:which kind of aluminum sheet could be bended after being etched?
general etching materials include stainless steel and copper.
Q:identify and clasify the products made from aluminium?
airplanes are made from aluminum. certain beverages are also. aluminum is cheaper and lighter. the biggest problem is the amount of electricity that it takes to make aluminum
Q:Using aluminum to cast aluminum?
Aluminum okorder.com/... I use investment lost wax casting.
Q:aluminum boat vs fiberglass?

Q:Bohr Model?! Aluminum?
An atom is made up of protons. electrons and neutrons. The protrons and neutrons are located in the nucleus, while the electrons are located on the shells outside the nucleus. Think of the shells as orbits, orbits which can only hold a certain amount of electrons. In the Bohr's model of Aluminum there will be 2 elctrons on the first shell, 8 electrons on the second shell, and 3 electrons on the last shell.
