Our company's PE Coated Aluminum Coil/Sheet have been widely used in the fields of construction and decoration(garage doors, ceiling etc.), electronic appliances, lighting decoration, air-condition air pipe, sanwich panels and drainage, etc.

Q: Can aluminum coils be used in chemical processing plants?: Yes, aluminum coils can be used in chemical processing plants. Aluminum is a versatile and widely used material in various industries, including chemical processing. It has excellent corrosion resistance properties, which make it suitable for handling and transporting various chemicals. Aluminum coils can be used in heat exchangers, condensers, evaporators, and other equipment in chemical processing plants. Additionally, aluminum coils offer lightweight and high thermal conductivity, which allows for efficient heat transfer and energy savings. However, it is important to consider the specific requirements and compatibility of the chemicals being processed to ensure that aluminum coils are suitable for the intended application.

Q: Can aluminum coils be used in the manufacturing of cans?: Yes, aluminum coils can be used in the manufacturing of cans. Aluminum coils are often used to produce the thin sheets of aluminum that are then formed into cans. The coils are typically processed through a series of steps, including rolling, annealing, and slitting, to create the desired thickness and width for can production. The aluminum sheets are then cut into appropriate sizes and shaped into the familiar cylindrical can shape. Aluminum is a popular choice for can manufacturing due to its lightweight, durable, and corrosion-resistant properties. It also provides a barrier to light, oxygen, and moisture, helping to preserve the quality and shelf life of the contents inside the cans. Overall, aluminum coils are an essential component in the manufacturing process of cans and play a significant role in the packaging industry.

Q: How are aluminum coils cut to size?: Aluminum coils are typically cut to size using specialized coil slitting machines. These machines have rotating circular blades that make precise cuts along the length of the coil. The coil is fed through the machine, and the blades cut the aluminum into the desired width. The cut pieces are then collected and further processed or used for various applications.

Q: What are the elements and compounds that make up an aluminum coil?: The chemical composition of an aluminum coil is primarily aluminum (Al), which is a lightweight, malleable, and ductile metal. It is usually represented by its elemental symbol 'Al' and has an atomic number of 13. Aluminum is often alloyed with other elements to improve its strength and performance. Common alloying elements include copper (Cu), magnesium (Mg), manganese (Mn), silicon (Si), and zinc (Zn). These elements are added in varying percentages depending on the specific properties required for the aluminum coil's application. The purity of aluminum in a coil can range from 99.00% to 99.7%, with the remainder being trace amounts of other elements.

Q: What is the typical thermal conductivity of aluminum coils?: Aluminum coils typically exhibit a thermal conductivity ranging from 205 to 220 W/mK. Renowned for its exceptional thermal conductivity, aluminum stands as a favored option for heat transfer purposes, notably within HVAC systems, refrigeration units, and heat exchangers. The remarkable thermal conductivity of aluminum facilitates effective dissipation and transfer of heat, thereby guaranteeing peak performance and energy efficiency in said systems.

Q: What is the typical yield strength of aluminum coils?: The typical yield strength of aluminum coils can vary depending on the specific alloy and temper used. However, for many common aluminum alloys, the yield strength typically ranges from 15,000 psi to 40,000 psi (100 MPa to 275 MPa). It is important to note that this is a general range, and there can be variations within different aluminum coil products. Additionally, the yield strength can also be influenced by factors such as the thickness and processing conditions of the coil.

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: How do aluminum coils compare to copper coils in terms of performance?: Aluminum coils and copper coils are two common types of heat exchanger coils used in heating, ventilation, and air conditioning (HVAC) systems. While both materials are effective in transferring heat, they do differ in terms of performance. Copper coils have long been the preferred choice for HVAC systems due to their superior heat transfer properties. Copper is an excellent conductor of heat, allowing for efficient transfer of thermal energy. This means that copper coils can cool or heat the surrounding air more effectively, resulting in faster and more efficient temperature control. On the other hand, aluminum coils are less efficient in terms of heat transfer compared to copper coils. Aluminum is a poorer conductor of heat, which means that it requires a larger surface area to achieve the same level of heat transfer as copper. Consequently, aluminum coils tend to be larger in size to compensate for their lower heat transfer capabilities. However, aluminum coils do have some advantages over copper coils. Firstly, aluminum is a lightweight material, making it easier to handle and install. This can be particularly beneficial in situations where weight restrictions or handling limitations are a concern. Secondly, aluminum coils are more resistant to corrosion compared to copper coils. Copper is prone to corrosion over time, especially in environments with high humidity or exposure to certain chemicals. Aluminum, on the other hand, naturally forms a protective oxide layer that helps prevent corrosion. This can result in longer-lasting coils and a lower likelihood of refrigerant leaks. In summary, while copper coils offer superior heat transfer capabilities, aluminum coils have their own advantages such as lighter weight and better corrosion resistance. The choice between aluminum and copper coils ultimately depends on the specific requirements of the HVAC system, including the desired performance, budget, and environmental factors.

Q: Is it possible to use a welding process to join two pieces of aluminum coil?: Yes, you can weld two pieces of aluminum coil together, but it requires specific techniques and equipment. Aluminum welding is different from steel welding and requires a TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas) welding process. It's crucial to use a clean, dry aluminum filler rod and maintain a clean, oxide-free surface on the aluminum. Additionally, a shielding gas like argon is necessary to protect the weld area from oxidation. Special precautions must be taken due to aluminum's high thermal conductivity and reactivity, so it's recommended to have experience or professional guidance when welding aluminum.

Q: Is it safe to use aluminum coil for food storage?: Using aluminum coil for storing food is not recommended. Aluminum can react with acidic or alkaline foods, potentially leaching aluminum into the food. This can be harmful to health, especially over time. Instead, opt for food-safe materials like glass, stainless steel, or BPA-free plastics for food storage to ensure safety and prevent contamination.
