Polishing Machined Aluminum to a Mirror Finish

Polishing Machined Aluminum to a Mirror Finish



This is one of many strategies to get aluminum to a mirror finish. If you have sandpaper, a buffing wheel, and some compounds, you can get pretty close to mirror. To get clearer and clearer finishes, you can chrome plate, electro-polish, or do it the way NASA recommends.


Step 1: Machine the Aluminum

Picture of Machine the Aluminum
I started with machined aluminum from a Haas Mill, which saves a lot of sanding time. I recommend using the facing tool on all the flat surfaces you need to make shiny. End-mills are okay, but not as good. For this (kinda) cube, I rotated the piece and faced (with a facing tool) every side that was going to be polished. The sides of end-mills were leaving machine marks that were too deep.


Step 2: Sand to the Highest Grit You Have

Picture of Sand to the Highest Grit You Have
Because I had machined it with a very precise machine before all this, I could start with 1200 grit wet/dry sandpaper. After getting rid of all the machine marks, I sanded it with 1500, and then 2000, giving it enough time on each to make sure all of that surface gets to that grit-level.

You can see from my set up that I clamped the sandpaper down using a random piece of metal, to a flat table that I've cleaned off before. (Any dirt underneath will only cause scratches in your finish). Wetting the paper makes it stick to the table as well, giving it you a flat surface to push against. Every once in a while, I would rinse off the grit in a bucket of water right next to my whole setup.


Step 3: Buffing Wheel + Rouge

Picture of Buffing Wheel + Rouge
The next and magical step is to hit the surfaces with a buffing wheel. At Pier 9, I used a cotton wheel on the Burr King and applied some brown rouge to to it, after knurling and cleaning the cotton a bit. Use the rouge sparingly, otherwise you'll end up with streaks of it on your metal. I placed a spongy mat underneath the wheel, just in case the Burr King caught an edge and flung it to the ground. Be sure to not even come close to the edge that will catch (like I did). Simply flip the piece around and buff from a different direction.

I sand and buff all in the same direction. This is not necessary, but it creates a uniform sheen on it at each stage which makes it easy to see what you have yet to sand/buff.

You should see it become reflective after just a light touch on the buffing wheel. Buffing it further will give it a little more clarity.


Step 4: Hand Buffer + Metal Polish

Picture of Hand Buffer + Metal Polish
Apply some appropriate metal polish, and follow the directions on the back of the tube. At Pier 9, we have a buffing hand-tool with some nice cotton buffing heads. This saves some time and arm movements of rubbing the polish in. But after buffing it, you still need to rub the compound away with a clean microfiber cloth. If you watch the video, it's kinda magical to rub away this black tarnish to reveal a near-mirror finish.

And that's it! Be patient, and whatever strategy you use, try it on a test piece first. There are a lot of little nuances that only come with doing it a few times.

Step 5: Take Some Selfies and don't touch it without gloves on.

Mirror aluminum sheet metal is the eye of the art

Mirror aluminum sheet metal is the eye of the art



Speaking of mirror aluminum sheet metal, the first reaction is the reflective material of lighting industry. Nowadays, it is no longer just reflective material, because of its beautiful appearance and superior performance, it is recognized by more and more industries, mirror aluminum is also favored in the construction industry, the France Louvre Lens branch project built in 2012 is the best description which use of a large number of mirror aluminum sheet indoor and outdoor.



The French Louvre Lens Branch is a unique project in the world. Ordinary aluminum sheet can not meet the needs of this design for reflective levels, but the mirror aluminum sheet can do it. While exhibiting exhibits in the Louvre Lens Branch in France, visitors are attracted by the magnificent atmosphere interior and exterior mirror walls. Looking from outside, the mirror aluminum bring the curtain wall noble and elegant art, its establishment is undoubtedly add the cultural atmosphere which enough to change the old mining area image. Mirror aluminum and glass build a rectangular modern pavilion, showing a very different style with the Paris Museum, giving the Louvre a new era. Into the interior of the museum, mirror effect of the exhibits will be set off to make life, so that the indoor visual effects more illusory and open. Mirror aluminum sheet metal is the art eye.


The best mirrors are in Germany,china and Italy. Japan's mirrors are oxide-free and are standard-sized sheets with high losses, but their unique textured effect is favored by manufacturers of electronic and signage casing.

if you want to do high-end products, then use the imported mirror, low-end, then choose domestic. Domestically made mirror is characterized by no protection of the surface treatment, mirror aluminum will change over time, the price is cheap; imported products are characterized by a stable reflectance, 86% of the ordinary mirror and 95% of the super-mirror two grades, the price to a little more expensive.

The processing technology of aluminum embossed sheet

The processing technology of aluminum embossed sheet

As early as many years ago, the industrial aluminum sheet usually through cutting, carving, milling and other processes, these processes are completed through the equipment to improve the shape and performance. Among them, the processing technology of aluminum embossed sheet is more complex than ordinary aluminum sheet. Let us go to understand the processing technology together.

Now many factories using intelligent equipment - computer controlled CNC machine, it built-in CAD mapping software. We compiled the needed shape of the aluminum plate into the computer, after a period of time, we can get the aluminum sheet we need. The anti-skid effect, decorative effect of aluminum embossed sheet is very good, so it is one of the main types of industrial aluminum. In order to press out the lines of aluminum sheet, the drawing process is used. In simple terms, the external force the metal go through the mold, the cross-sectional area of the metal is compressed, resulting in a variety of lines. And retention of metal texture form, gloss and characteristics of its surface for different treatment. This drawing process makes the aluminum embossed sheet with anti-rust, anti-oxidation and chemical reagents and other properties. 

It is because of excellent processing technology, which makes the modern technology more perfect and efficient, at the same time, the performance ofaluminum embossed sheet has also been improved greatly. Whether it is material selection or performance, all have a significant improvement. With the improving processing technology, there will be more and more people tend to choose this kind of healthy fashion sheet.

embossed aluminium sheet stucco embossed aluminum sheet has many uses across a number of industries. It is used in education, manufacturing, medical and more. Stucco sheet is available in Alloy 1150A / H14.
embossed aluminium sheetis more durable than plain aluminium sheet of similar charactiristics. Stucco embossing also reduces the light-reflecting ability of the metal. This is due to the pebble-like surface, which is imprinted once the aluminium has been given the required finish. Finally, stucco embossed aluminum sheet always looks more presentable.

Aluminum plate manufacturers talk about the reason of the aluminum plate

Aluminum plate manufacturers talk about the reason of the aluminum plate



With the continuous development of China's economy, the demand for aluminum plate is increasing. But the quality of aluminum plate is also has certain defects, production experience, production of  aluminum plate aluminum plate tend to have the phenomenon of brittle, so this is what causes, below small make up to tell you something about the causes, and how to change this phenomenon:

1, due to shunt bar is usually caused by poor convergence performance should be appropriately increased muscle and outside surface, reinforcement and reinforced the confluence of the length, or increase the compression ratios, the change of the die head pressure can change the die head straight length to adjust the material flow resistance; Different compression ratios can be selected to change the extrusion pressure in the mold design stage, but it must be noted that the compression ratio of the machine head is suitable to the compression ratio of the extruder screw. By changing the formula, the extrusion process parameters can be adjusted to increase the size of the melt pressure.

2. Insufficient head pressure. The pressure of the die head is determined directly by the compression ratio of the die, especially the length of the flat section. The compression ratio of the die head is too small or the flat section too short will cause the product not dense, affect the physical performance.

3. Unreasonable cross section design, especially the distribution and interface Angle of the inner ribs. This will result in a stress concentration phenomenon that needs to be improved to design and eliminate the right angles and acute angles at the interface.

Analysis of common problems of 5052 aluminum plates

Analysis of common problems of 5052 aluminum plates

The most common use of the 5052 aluminum plates is the appearance or electronic parts. The common problems of 5052 aluminum plates are as follows:


There are defects on the surface of the aluminum sheet.

The surface problem of 5052 aluminum plates, except for the case and billet, is derived from the production process of each machine.

2. After oxidation, color difference, black silk, sand hole and other defects.

Black silk can be caused by many reasons, such as the accessory machine drops of the mill on the oil due to poor management, such as stress or too much tension on the surface of indentation, if again to the thin material of rolling, the dark mark will become more and more to the more thin, dark lines or black line, and sometimes even can't distinguish oil or mark, even can't see what's the color on the surface, but were very obvious after oxidation, for the customer, see inconsistent phenomenon appearance, affirmation is to refuse. After oxidation, black silk is the most effective. Once this happens, there is almost no room for survival, and the loss and consequences are irreparable. Second off color, generally do look more products, also cannot appear off color, any customer is unwilling to accept a similar "two leatherface" products, in order to eliminate these problems, or want to rely on the source machine to control.

The reasons of sand hole, sand hole is commonly internal structure problem, because when slab ingot impurities or didn't rule out clean water, or other elements not mix factors such as, so request in ingot casting the source link to control testing.

3. Performance requirements: tensile strength, hardness, elongation, bending requirements, etc.

As for performance problems, the most is the bending deformation, this link because the customer product use different, cannot treat as the same, but in general the annealing at this stage, how many temperature, how long, how thick to retreat, there is a standard.

5052 aluminum plate has wide USES, the product is classified, but as long as pay attention to each link of the controls, to the common problem in source control, process stability, make sure to attract market products!

Storage of Aluminum Sheet, Aluminum coils and Aluminum Extrusions

Storage of Aluminum Sheet, Aluminum coils and Aluminum Extrusions



if at all possible, do not stack the aluminum plates in a flat stack on the ground. Storage in this way traps water between the sheets, increasing corrosion rates. Instead, stack the plates on edge to allow water to drain between the pieces. If sheets must be stacked flat, remove any paper interleaving or packing from between the plates. If left in place, the paper will act as a wick and draw water into between the plates. If the sheets are stacked flat, try not to stack one sheet directly on top of another. Instead, insert small wood or aluminum “stickers” between the sheets to let water drain.

Which Aluminum Alloy plate You Are Welding?

Which Aluminum Alloy plate You Are Welding?

It isn’t enough to know that you are welding aluminum plates . Welding professionals have to know which alloy is about to be welded, and they have to know the correct filler metal to use. The most common alloys used in shipbuilding are the Al-Mg 5XXX sheet alloys and the Al-Mg-Si 6XXX extrusion alloys, primarily because of their excellent resistance to corrosion.

Most Aluminum Alloy plates are easily arc weldable. Virtually all of the alloys in the 1XXX, 3XXX, 4XXX, 5XXX and 6XXX series can be arc welded using GTAW and GMAW. However, most of the alloys plates  in the 2XXX and 7XXX series cannot be arc welded. The only arc weldable alloys in the 2XXX series are 2219 and 2519. Almost all of the other 2XXX alloys will crack severely when welded. Similarly, the only alloys in the 7XXX family that can be arc welded are 7003, 7004, 7005 and 7039.

Specifically, be particularly wary of 2024 and 7075 aluminum plate. It is tempting to buy one of these alloys for repair welding because they are strong and commonly available, but they are crack-sensitive to arc welding.

Welding an “unweldable" alloy or using the wrong filler alloy can result in immediate cracking or a premature failure in service at a later time.
