FAQ

Alumina is the protective coating that covers aluminum when exposed to oxygen. It's actually corroded aluminum that prevents the aluminum from continuously corroding.What I didn't know until recently was that alumina is an electrical insulator. If that's the case why then isn't aluminum an insulator if one is trying to pass current along its surface?

Corroded aluminum is not the same substance as rust is not the same as iron. Iron is simply Fe, rust is Fe2O3 if I am correct. So the alumina is not the same as aluminum. Just because something has an element in it doesn't mean it has the properties of the material, or is even similar to that element in anyway. Glass is conductive when its molten, but not when its cool and hard, like windows. So unless what you are dealing with is exactly the same thing, you can't assume anything about it, generally. EDIT: Aluminum is Al, alumina is Al2O3. Alumina is an oxide, aluminum is a pure element, they aren't the same so they can have different properties. As for being an insulator, the layer of alumina is usually so thin it only adds a small amount of resistance to a circuit. If you had a block made of pure alumina and you tried to run current through it it would add lots of resistance or so much there would be virtually no flow.

What kind of aluminum sheet can be bent with five millimeters?

Aluminum plate can not be called grade, I give the high-speed rail processing bending sound barrier is aluminum, bending effect is very good.

To achieve a flawless mirror-like appearance on aluminum sheets, a series of procedures must be undertaken to eliminate any flaws and create a sleek, reflective surface. The crucial steps involved are as follows: 1. Surface preparation: Commence by meticulously cleansing the aluminum sheet to eliminate any dirt, grease, or other contaminants. Utilize a mild detergent and water to accomplish this task. Thoroughly rinse the surface and ensure it is completely dry. 2. Sanding: Employ increasingly finer grades of sandpaper or abrasive pads to eliminate any scratches, oxidation, or unevenness on the aluminum surface. Begin with a coarser grit (around 120-180) and gradually progress to finer grits (up to 1000 or higher) to attain a smoother texture. It is essential to sand consistently in one direction to avoid visible scratches. 3. Polishing compounds: Administer a polishing compound or specialized metal polish designed explicitly for aluminum surfaces. Employ a soft cloth or a buffing wheel to apply the polish and work it into the surface. Apply gentle pressure and distribute the polish evenly by executing circular motions. Repeat this step until the desired level of shine is achieved. 4. Buffing: Utilize a buffing wheel, preferably composed of felt or cotton, to further enhance the luster. Apply a small quantity of a high-quality polishing compound to the wheel and meticulously buff the aluminum sheet in a consistent manner. Employ circular motions and maintain an unwavering, even pressure. 5. Final polishing: To attain an impeccable mirror-like finish, employ a specialized aluminum polish or a metal finishing compound. Apply a small amount onto a clean cloth and gently rub the surface using circular motions. This final step aids in eliminating slight scratches or imperfections, augmenting the brilliance of the aluminum sheet. Remember to meticulously cleanse the aluminum sheet after each step to eliminate any residue or excess polish. Furthermore, always adhere to the manufacturer's instructions when utilizing specific polishing compounds or tools as they may provide specific guidelines for optimal outcomes. By diligently following these steps, you can achieve a mirror-like finish on aluminum sheets, transforming them into highly reflective surfaces that are visually captivating and functionally efficient.

Trying to find the best aluminum powder I can buy for rocket engines and pyrotechnic (fireworks) uses?

It really depends on your formula and how the aluminum is being used in the formula. Is it a part of the fuel or is an additive to the fuel for sparks?

There are several methods that can be used to finish aluminum sheet edges, depending on the desired outcome and application. One common method is deburring, which involves removing any sharp or rough edges from the aluminum sheet. This can be done using various tools such as files, sandpaper, or specialized deburring machines. Deburring not only improves the appearance of the edges but also helps to prevent any potential injuries or accidents caused by sharp edges. Another method is chamfering, which involves creating a beveled edge on the aluminum sheet. This can be achieved using chamfering tools or by carefully filing or sanding the edges at a specific angle. Chamfering is often done to enhance the aesthetics of the aluminum sheet and to make it easier to handle and assemble. Additionally, edge rounding is a technique that involves smoothing the edges of the aluminum sheet to create a rounded or curved profile. This can be done using tools such as sanders, grinders, or specialized edge rounding machines. Edge rounding not only improves the visual appeal of the aluminum sheet but also helps to reduce the risk of injury from sharp edges. Furthermore, anodizing is a popular finishing method for aluminum sheet edges. Anodizing involves creating a protective oxide layer on the surface of the aluminum through an electrochemical process. This not only enhances the corrosion resistance of the aluminum but also provides a range of color options for the edges, allowing for customization and improved aesthetics. Lastly, powder coating is another method that can be used to finish aluminum sheet edges. Powder coating involves applying a dry powder onto the surface of the aluminum and then heating it to create a durable and decorative finish. This method offers a wide variety of colors, textures, and finishes, allowing for customization and enhanced visual appeal. Overall, the choice of finishing method for aluminum sheet edges will depend on factors such as the desired appearance, functionality, and application requirements. It is important to consider these factors and consult with experts to determine the most suitable method for a specific project.

I was looking at Audioque subs earlier and what is the difference between copper and aluminum coiled subs. do aluminum last longer or something?

Aluminum is stronger than copper. It takes more aluminum to make something strong as steel. However copper conducts electricty ans signals better than aluminum. People are switching to aluminum cause its cheaper.

8mm which type of aluminum plate is suitable for bending?

What is your bending angle?If only bending is required, the quality of the aluminum sheet is of little concern.First of all, the state is the most important, the state is divided into hard, semi hard, soft (usually soft called O state)(1) the bending effect of the whole hard is not too far (the aluminum plate is H18, H19, H38 and so on are all hard)(2) the aluminum sheet in the semi hard state can be basically bent (H24, that is, semi hard)(3) the bending of the O state is certainly not a problem, but as a result of being too soft, there is little bending in this stateSecond, you have to choose pure aluminum or alloy aluminum?Pure aluminum hardness is not very good, with 1100, 1050, 1060 and so on can be recommended 1100 H26Alloy aluminum hardness is better, can use 3003, 3005, 5052 and other semi hard state can be.

Would you please tell me what putty to use on the aluminium board, what kind of putty, and the painting process?

Applied atomic ash.Consider adding an interface agent, that is, applying an interfacial agent on the aluminum plate, and then applying a topcoat on the interface agent after drying.You can also consider adding primer or putty, and then spray paint.In summary, adhesion of the topcoat is reinforced with an agent.
