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: What are the typical lead times for ordering aluminum coils?
- The typical lead times for ordering aluminum coils can vary depending on various factors such as the supplier, quantity, customization requirements, and current market conditions. However, on average, lead times can range from a few weeks to a couple of months. It is advisable to contact the specific supplier for accurate information regarding their lead times.
- Q: What is the common color of aluminum coil membrane?
- The blue transparent membrane is the most common.
- Q: How exactly can you tell (just by looking) that the nipple used to tighten a spoke is brass and not aluminum? I know some are silver - not sure if they are painted silver or what. But without scraping or causing any damage to the nipple, how would one know for sure if they have no experience between the two.p.s. I don't know how heavy or light either is, so if that is one way to tel, it's not a good way for me.
- Commercially pure aluminum has a tensile strength of approximately 90MPa and can be improved to around 180MPa by cold working. Typical Brass alloys have tensile strengths in the range 250 - 500MPa. There maybe different brass materials which exceed this limit. There may be those which are lower in tensile strength than the minimum of this range. Check in the web. But, according to these data, you can see that Brass is stronger than Aluminum. So, the brass plate is stronger than the Al plate. However, Aluminum is a pure metal. Brass is an alloy. So, there maybe different brasses depending on their composition.
- Q: What is the cost involved in the production of an aluminum coil?
- <p>The cost to produce an aluminum coil varies significantly based on several factors. These include the cost of raw materials, energy costs for melting and rolling, labor, and overhead expenses. Additionally, the price of aluminum on the commodities market directly impacts the cost. As of recent market trends, the cost can range from a few hundred to several thousand dollars per ton, depending on the specific alloy and thickness of the coil. It's essential to consider the current market prices for aluminum and the efficiency of the production process when calculating the cost to produce an aluminum coil.</p>
- 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?
- Anodising is a process in which the surface of a metal is modified. In the case of anodising aluminum the layer of aluminum oxide is made thicker. This is done by placing the aluminum in a sulfuric acid solution and passing a current through it so that it serves as an anode-the current releases oxygen at the surface of the aluminum increasing the aluminum oxide. I'm pretty sure this is from the reaction of the electric charge and the sulfuric acid producing oxygen as you showed in your last reaction with water. I hope this was helpful, I'm at work and don't have my old chem books and I dont' remember all this stuff off the top of my head.
- Q: This question asks if aluminum coils are suitable for use in cold weather conditions.
- <p>Yes, aluminum coils can be used in cold climates. Aluminum is a highly durable material that retains its strength and conductivity even in low temperatures. It does not rust or corrode, making it ideal for outdoor applications in cold weather.
