Product Description
Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates.
Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically. In keeping with its pervasiveness, aluminium is well tolerated by plants and animals. Owing to their prevalence, potential beneficial (or otherwise) biological roles of aluminium compounds are of continuing interest.
The earliest citation given in the Oxford English Dictionary for any word used as a name for this element is alumium, which British chemist and inventor Humphry Davy employed in 1808 for the metal he was trying to isolate electrolytically from the mineral alumina. The citation is from the journal Philosophical Transactions of the Royal Society of London: "Had I been so fortunate as to have obtained more certain evidences on this subject, and to have procured the metallic substances I was in search of, I should have proposed for them the names of silicium, alumium, zirconium, and glucium."

- Q:How are aluminum coils tested for surface hardness?
- Aluminum coils are tested for surface hardness through a variety of methods to ensure their quality and suitability for various applications. One common method used is the Rockwell hardness test. In the Rockwell hardness test, a diamond or hardened steel ball is pressed into the surface of the aluminum coil using a specified amount of force. The depth of the indentation made by the ball is measured, and a hardness value is determined based on the difference in depth before and after applying the force. This value is then compared to a hardness scale to determine the surface hardness of the aluminum coil. Another method used is the Brinell hardness test. In this test, a hardened steel ball is pressed into the surface of the aluminum coil using a specified force. The diameter of the resulting indentation is measured, and a hardness value is calculated based on the applied force and the size of the indentation. This value is then compared to a hardness scale to determine the surface hardness of the aluminum coil. Both the Rockwell and Brinell hardness tests are non-destructive and provide accurate measures of the surface hardness of aluminum coils. These tests help manufacturers and customers ensure that the coils meet the required hardness specifications for their intended applications, such as in the automotive or construction industries. By testing for surface hardness, potential issues like brittleness or inadequate strength can be identified and addressed before the aluminum coils are used in the production process.

- Q:my text says aluminium does not corrode much as a passive aluminium oxide layer is formed on it.Well other metals such as sodium adn potassium also form oxides. Why dont their oxides prevent further oxidation ?
- sodium oxide and potassium oxide are water soluble aluminium oxide is not water soluble. the layer formed of oxide on the aluminium surface is coherent and adherent with no pores and stuck to the metal surface. the layer is also passive to most acids and alkalies except HCl and anti passive ions if present. sodium oxide and potassium oxide dissolve in any aqueous medium forming the corresponding alkalies NaOH and KOH leaving the fresh metal surface exposed to more corrosion. also the reaction of Na and K with aqueous media like water and acids is quite vigorous and fast unlike aluminium which is mu less reactive
- Q:Can aluminum coils be used in the manufacturing of cans?
- Aluminum coils play a crucial role in the production of cans. They are commonly utilized to manufacture thin aluminum sheets, which are subsequently molded into cans. To achieve the desired thickness and width for can production, the coils undergo a series of steps, including rolling, annealing, and slitting. Once the aluminum sheets are prepared, they are cut into suitable sizes and shaped into the familiar cylindrical can form. Aluminum is a favored material for can manufacturing because of its lightweight, durable, and corrosion-resistant properties. Moreover, it serves as a protective barrier against light, oxygen, and moisture, thus ensuring the preservation of the contents' quality and shelf life. In summary, aluminum coils are an indispensable element in the can manufacturing process and play a significant role in the packaging industry.
- Q:Can aluminum coils be used in chemical processing equipment?
- Yes, aluminum coils can be used in chemical processing equipment. Aluminum is known for its excellent corrosion resistance, making it suitable for use in many chemical environments. It is resistant to a wide range of acids, alkalis, and other corrosive substances.

- Q:How many atoms are there in a piece of aluminum foil, 7.3 inches in length and 12.0 inches in width, and 0.141 mm thick? According to this problem, aluminum foil is a flat-rolled product, rectangular in cross section, of thickness from 0.006(0.15mm) to 0.00025(0.006mm). The density of Al is 2.699 g/cm3.
- What you want to do is determine the mass of the piece of aluminum foil and then convert that to number of atoms. I'll give some pointers and you can fill in the rest: 1. Calculate the mass of the foil: a. Convert the length and width of the foil into centimeters. b. Convert the thickness of the foil into centimeters. Use your 0.141 mm figure. c. Now multiply the length times width times the height to give you the volume in centimeters. d. Now multiply this volume calculated in step c times the density of aluminum. That will give you the mass of your piece of foil. 2. Convert this mass into number of atoms. a. From the periodic table you know that there are 26.982 grams per mole of Al b. There are 6.02 x 10^23 atoms in a mole. c. So, take the mass calculated in Part 1 and divide it by 26.982 grams per mole of Al. That will give you the number of moles of Al in your piece of foil. d. Now take this number of moles and multiply it by 6.02 x 10^23 atoms in a mole, and that will give you the number of atoms in your piece of foil.
- Q:For the reaction at the anode:Al ----gt; Al3+ + 3eHowever, at the anode, oxygen are also produced and forms aluminium oxide(Al2O3) with aluminium.Are Oxygen produced by oxidation of water by electrolysis? or some reaction else?If Oxygen are produced by oxidation of water, then why it can be oxidise sinceAl ----gt; Al3+ + 3e E^0= + 1.66V2H2O ---gt; O2 + 4H+ + 4e E^0= - 1.23V(if refers to E null value) Oxygen should only be produced after all the Al have been finish oxidised.Both reaction happen at the same time? Is it possible?
- with respect to your massege, i must say that it depends of what electrode you choice for your work. but with refer to E i think oxidation of watter do not interference with oxidation of Al and only oxidation of Al happen .
