Q:could you please help me find information of the element aluminum??? all the information i can get will be great... thanks very mucho.... who discovered? where can i find pictures of it?: hi ive found this: Aluminium is a silvery white member of the boron group of chemical elements. It has the symbol Al and its atomic number is 13. It is not soluble in water under normal circumstances. Aluminium is the most abundant metal in the Earth's crust, and the third most abundant element, after oxygen and silicon. It makes up about 8% by weight of the Earth's solid surface. Aluminium is too reactive chemically to occur in nature as a free metal. Instead, it is found combined in over 270 different minerals.[5] The chief source of aluminium is bauxite ore. 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 very important in other areas of transportation and building. Its reactive nature makes it useful as a catalyst or additive in chemical mixtures, including ammonium nitrate explosives, to enhance blast power. Aluminium is a soft, durable, lightweight, ductile and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. Aluminium is nonmagnetic and nonsparking. It is also insoluble in alcohol, though it can be soluble in water in certain forms. The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa.[6] Aluminium has about one-third the density and stiffness of steel. It is easily machined, cast, drawn and extruded.

Q:Can aluminum coils be used in the production of aluminum windows?: Yes, aluminum coils can be used in the production of aluminum windows. Coils are often used to create the frames and profiles of aluminum windows, as they can be easily shaped and formed into the desired configurations. This makes aluminum a popular material choice for window manufacturers due to its lightweight, durability, and corrosion-resistant properties.

Q:What are the common surface defects or issues in aluminum coils?: Aluminum coils may exhibit various surface defects or issues that can arise from different causes. These defects can have detrimental effects on the appearance, quality, and functionality of the coils. Therefore, it is crucial for manufacturers and users to be mindful of these defects and implement necessary measures to prevent or reduce their occurrence. Scratches, for instance, are visible marks on the coil surface that result from contact with abrasive materials or mishandling during production, transportation, or storage. Streaks, on the other hand, manifest as long, narrow lines or bands on the coil surface, often caused by irregularities in the rolling process or impurities present in the aluminum material. Dents are localized depressions or deformations that can occur due to mishandling, accidental impacts, or improper storage practices. Corrosion, though aluminum is generally resistant, can arise from specific environmental conditions or exposure to corrosive agents, leading to the formation of oxide layers or pitting on the coil surface. Edge cracks refer to fissures that appear along the coil edges, resulting from improper cutting or shearing during manufacturing. Surface roughness, characterized by an uneven or bumpy texture, can arise from inadequate smoothing or finishing during rolling or processing. Oil stains may be observed as dark or discolored areas on the coil surface, caused by improper cleaning or lubrication during production. Coil set refers to the coil's tendency to retain a curvature or shape after unwinding, resulting from stresses induced during rolling, coiling, or cooling, leading to an uneven and non-flat surface. Roll marks are patterns or imprints left on the coil surface by the rolling mill or equipment, caused by uneven pressure or improper tool alignment. Discoloration, characterized by changes in color or appearance, can result from exposure to high temperatures, chemical reactions, or oxidation. It is essential to recognize these surface defects and their potential impact on the quality and performance of aluminum coils. By taking appropriate preventive measures, manufacturers and users can minimize these defects and ensure the desired appearance and functionality of the coils.

Q:How do aluminum coils perform in saltwater environments?: Aluminum coils perform exceptionally well in saltwater environments due to their natural resistance to corrosion. Unlike other metals, aluminum forms a protective oxide layer when exposed to saltwater, creating a barrier that prevents further corrosion. This oxide layer acts as a durable and long-lasting shield against the harsh effects of saltwater, ensuring the longevity and performance of aluminum coils in marine applications. Additionally, aluminum coils are lightweight and possess high thermal conductivity, making them popular choices for heat exchangers and condensers in saltwater-based cooling systems. Overall, aluminum coils are highly reliable and efficient in saltwater environments, making them a preferred choice for various marine applications.

Q:What are the different coil slitting methods used for aluminum coils?: There are several coil slitting methods used for aluminum coils, including rotary shear slitting, loop slitting, and simultaneous multi-blanking. These methods involve different techniques and equipment to precisely cut and separate aluminum coils into narrower strips or sheets. Each method has its advantages and is chosen based on factors like coil thickness, width, and desired output.

Q:show step by step: First write out the formula reaction: 4Al + 3O2 --- 2Al2O3 Next, find the number of moles of oxygen gas needed to oxidize 3.42 g of aluminium completely. From the cchemical equation above, 3 mol of oxygen is used to oxidize completely 4 mol of aluminium. Calculate the no. of moles of aluminium used: no. of moles of aluminium used = 3.42 g / molar mass of Al = 3.42 g / 26.98 g mol^-1 = 0.127 mol Use the mole ratio concept to find the no. of moles of oxygen required: no. of moles of oxygen required : no. of moles of aluminium used = 3 : 4 no. of moles of oxygen required / 0.127 = 3 / 4 no. of moles of oxygen required = (3 / 4)(0.127) = 0.095 mol Next, use the gas equation PV = nRT [P: Pressure of gas in Pa; V: Volume of gas in m^3; n: no. of moles; R, gas constant, 8.314 J mol^-1 K^-1; T, Temperature of gas in K] -Convert 0.975 atm to Pa: 0.975 atm = (0.975 x 101325) Pa = 98791.875 Pa -Convert 25 oC to K: 25 oC = (25 + 273) K = 298 K -Substitute into the equation PV = nRT and solve it: (98791.875)(V) = (0.095)(8.31)(298) (98791.875)(V) = 235.2561 V = 235.2561 / 98791.875 = 0.002381 m^3 = (0.002381 x 10^3) L = 2.381 L
