Q: This question asks for a comparison between aluminum sheets and other roofing materials in terms of their characteristics and performance.: <p>Aluminum sheets are lightweight and highly durable, offering excellent resistance to corrosion and weathering. They are energy-efficient, reflecting heat and reducing cooling costs. Compared to materials like asphalt shingles, aluminum is more expensive but lasts longer, with a lifespan of 40-50 years. Unlike clay or concrete tiles, aluminum is less prone to breakage and is easier to install. It also doesn't rot or warp like wood, and it's fire-resistant. However, it can be noisy during rain and is less visually appealing than some other materials, but its modern and sleek appearance can be a design advantage.</p>

Q: What are the different methods of surface protection for outdoor aluminum sheet?: There are several methods of surface protection for outdoor aluminum sheet to ensure its durability and longevity. 1. Anodizing: This is one of the most common methods used to protect aluminum surfaces. Anodizing creates a protective oxide layer on the surface, making it more resistant to corrosion, abrasion, and UV rays. It also improves the appearance of the aluminum sheet by providing a range of colors and finishes. 2. Powder coating: Powder coating involves applying a dry powder to the aluminum sheet and then baking it in an oven to create a hard, protective coating. This method provides excellent resistance to weathering, corrosion, and chemicals. It is also available in various colors and finishes. 3. Paint coating: Applying a paint coating is another effective way to protect outdoor aluminum sheets. The paint forms a barrier between the aluminum surface and the environment, preventing corrosion and enhancing aesthetics. It is important to use a high-quality paint specifically designed for aluminum to ensure proper adhesion and durability. 4. Clear coating: Clear coating is mainly used to protect the natural appearance of aluminum while providing a layer of protection against corrosion, oxidation, and UV rays. It is often applied after anodizing or polishing the aluminum sheet. 5. Laminating: Laminating involves adhering a protective film or sheet onto the aluminum surface. This method provides excellent resistance to scratches, abrasion, and UV rays. It is commonly used in applications where the aluminum sheet is subjected to heavy wear and tear. 6. Chemical conversion coating: Chemical conversion coatings, such as chromate conversion coating or phosphating, are used to improve the corrosion resistance of aluminum sheets. These coatings chemically react with the surface to create a protective layer that inhibits corrosion. It is important to consider the specific requirements and environmental conditions when choosing a method of surface protection for outdoor aluminum sheets. Each method has its own advantages and limitations, and the choice should be based on factors such as durability, appearance, cost, and maintenance requirements.

Q: I have tried every possible method that I could find on the web for cleaning aluminum, tungsten, filler wire. Nothing has seemed to work. I've tried looking for leaks in the argon line. I'm getting decent welds but there is gunk in the welds for sure. I'm worried about overall strength of the welds. Does anybody out there know of a tried and true method for cleaning aluminum, tungsten, filler etc. that is sure to work? If I can follow that method and still have problems It could possibly be a problem with the machine. Any help would be much appreciated.: Preweld cleaning requires two operations: oil/grease removal and oxide removal. As below, remove oils and greases first, then remove the oxide. Don’t reverse this order. Take the following steps before welding aluminum: 1. Remove oil, grease, and water vapor using an organic solvent such as acetone or a mild alkaline solution like a strong soap. You may also use citrus-based degreasers, but be sure to rinse and dry the part before welding. 2. Remove surface oxides with a stainless steel wire brush (used only for aluminum) or strong alkaline or acid. Many welding suppliers sell oxide-removal solutions in spray or squeeze bottles for local application. Exercise extreme care when handling these solutions, and again, rinse and dry the part before welding. 3. Assemble the joint. If it won't be welded immediately, cover the joint with brown Kraft paper to prevent dirt and grit in the air from getting into the joint. 4. Keep the aluminum dry and at room temperature. 5. Weld within a few days. Clean the joint again if it isn't welded within that time. Good luck!!!

Q: I have a friend to purchase a number of aluminum, used to make computer cooling plate. He asked me to help with the supplier, can I look at the Internet, there are many kinds of aluminum, would like to ask: what kind of computer cooling plate used to do a bit better? What are the suitable suppliers in Guangdong?: Copper heat conductivity is good, but the price is more expensive, difficult to process, the weight is too large (a lot of pure copper radiator is beyond the limit of CPU), the heat capacity is small, and easily oxidized. The pure aluminum is too soft, can not directly use, are the use of aluminum alloy to supply enough hardness, aluminum alloy is the advantage of low prices, light weight, but the heat conductivity is much worse than copper. Some of the radiator embedded in a copper plate in each in his element, Aluminum Alloy radiator base.

Q: Curtain wall aluminum plate reinforcement spacing between the number of appropriate, the country has no standard?: As to the stiffener of the aluminum veneer, what are the following points?:1, aluminum reinforcement spacing is generally around 600mm, in order to ensure the aluminum plate in the positive and negative pressure conditions within the scope of deformation. When aluminum plate is welded, there is internal stress due to welding deformation (this internal stress can not be completely eliminated for a long time), and the rigidity of reinforcing bar should also be increased.2. The sectional dimension and spacing of stiffeners shall be determined according to the calculated wind pressure of the aluminum plate. But it is worth noting that the reinforcement calculation of single aluminum plate strengthening is different from the glass curtain wall, first, its strength is certainly no problem (still not seen the wind blowing broken plate, there is no joke) deflection possibility, bend off and windy weather also very few people to pay attention to the single aluminum plate plate surface after deformation the scenery. Therefore, the calculation of deflection of stiffeners are considered under the condition of wind strength and deflection when the winds of aluminum can cause permanent plastic deformation.In fact, aluminum veneer manufacturers generally use the single aluminum plate edge folding groove made of aluminum and 20*40*20, installed in the distance about 600mm. Also useful for profile (grooved aluminum) stiffenersThe spacing between stiffeners is very important to the cost of production. Generally speaking, the spacing of stiffeners will be changed from 600 to 350, and the cost will be increased by 8~15 yuan / square meter

Q: How do you prevent fingerprints on aluminum sheets?: There are several strategies you can use to prevent fingerprints on aluminum sheets: 1. Opt for gloves: To avoid leaving fingerprints on aluminum sheets, a simple solution is to wear gloves while handling them. This creates a barrier between your hands and the surface, preventing any marks or smudges. 2. Thoroughly clean the surface: Before touching aluminum sheets, ensure that the surface is clean. Use a suitable cleaning agent or mild detergent to remove any dirt or oils. Dry the sheets completely with a lint-free cloth to minimize the chances of fingerprints sticking to the surface. 3. Apply a protective coating: Prevent fingerprints by applying a protective coating on the aluminum sheets. Clear lacquer or a clear protective film designed for this purpose are viable options. These coatings create a barrier that reduces the visibility of fingerprints and makes them easier to clean off. 4. Handle with care: Minimize direct contact with aluminum sheets to reduce the likelihood of fingerprints. Fingerprints are more likely to occur when pressure is applied or when the surface is repeatedly touched. Whenever possible, use tools or gloves to manipulate the sheets instead. 5. Proper storage: Ensure that aluminum sheets are stored in a clean and dust-free environment, away from potential contaminants. Consider using protective sleeves or covers to shield the sheets from fingerprints and other marks. By implementing these preventive measures, you can significantly decrease the occurrence of fingerprints on aluminum sheets, maintaining their cleanliness and visual appeal.

Q: I was quoted $5000+ to upgrade my house from 100A electric service to 400A. Part of the reason for the high cost is the cost of copper. What size copper wire is needed for 400A, and how much does it cost per foot? Would it be a lot cheaper to use aluminum wire?: They can be joined but only through a suitable device marked specifically for aluminum to copper connections. See website below.

Q: What are the different methods of surface cleaning aluminum sheets?: There are several methods for surface cleaning aluminum sheets, depending on the level of dirt or contamination present. Here are some of the most commonly used methods: 1. Mechanical Cleaning: This method involves physically scrubbing the surface of the aluminum sheet using brushes, abrasive pads, or sandpaper. It is effective for removing light dirt, grease, or oxidation. However, caution should be exercised to avoid scratching or damaging the surface. 2. Chemical Cleaning: Chemical cleaning involves the use of specific cleaning agents or solutions to remove dirt, stains, or oxidation from the aluminum sheet. Commonly used chemicals include alkaline cleaners, acidic cleaners, and solvents. It is important to follow the manufacturer's instructions and take necessary safety precautions when working with chemicals. 3. Pressure Washing: Pressure washing utilizes high-pressure water jets to remove dirt, grime, and other contaminants from the surface of aluminum sheets. It is a quick and efficient method, particularly for large or heavily soiled surfaces. However, care should be taken to avoid using excessive pressure, which may dent or damage the aluminum. 4. Electrolytic Cleaning: This method involves the use of an electrolyte solution and an electric current to remove corrosion, oxidation, or tarnish from the aluminum sheet. The sheet is submerged in the electrolyte bath, and the electric current helps to dissolve the contaminants. Electrolytic cleaning is particularly effective for heavily oxidized or tarnished surfaces. 5. Chemical Etching: Chemical etching is a process that uses a combination of chemicals to selectively remove the surface layer of the aluminum sheet. It is commonly used for removing anodized coatings or for creating decorative patterns on the surface. However, this method requires specialized equipment and expertise. It is important to note that the choice of cleaning method should be based on the specific requirements of the aluminum sheet, the level of contamination, and the desired outcome. It is always recommended to consult the manufacturer's guidelines or seek professional advice to ensure the most appropriate and safe cleaning method is used.

Q: why does the bubble apear a few minutes later after putting aluminum sheet into diluted hydrochloric acid?: Aluminum element is extremely activated and will react with oxygen, generating aluminum oxide, once being exposed in air, so there is a layer of aluminum oxide on the surface of daily aluminum products including aluminum sheet. When aluminum sheet is put into diluted hydrochloric acid, aluminum oxide on the surface will firstly react with hydrochloric acid, generating aluminium chloride and water, the process won’t generate bubble, but after finishing the reaction of aluminum oxide on the surface, when the exposed aluminum element reacts with hydrochloric acid, generating aluminium chloride and oxygen, the bubble appears.
