FAQ

Why does fillet appear when rolling aluminum coil?

How thick and wide is it when there is such problem? Which is the rolling pass? And what is the type of the rolling mill? The simple 4 rollers or CVC and HC rolling mill with roller control. Does the filler appear in rolling or out of roller? Different thickness will lead to different analysis.

I'm ball milling aluminum into powder and I have filled the canister with some water to prevent the aluminum from igniting. The powder has begun to dissolve in the water. I'd like to know the best way to remove the dissolved aluminum from the water so I can get to the powder.There is around of cup of water in the canister, just to give an idea of the situation.

Boil the water. The water will evaporate, leaving the aluminum behind.

I heared the aluminum weakens or melts.

Mercury readily combines with aluminium to form a mercury-aluminum amalgam when the two pure metals come into contact. However, when the amalgam is exposed to air, the aluminium oxidizes, leaving behind mercury. The oxide flakes away, exposing more mercury amalgam, which repeats the process. This process continues until the supply of amalgam is exhausted, and since it releases mercury, a small amount of mercury can “eat through” a large amount of aluminium over time, by progressively forming amalgam and relinquishing the aluminium as oxide. Aluminium in air is normally protected by a thin layer of its own oxide, which is not porous to mercury. Mercury coming into contact with this oxide does no harm. However, if any elemental aluminium is exposed (even by a recent scratch), the mercury may combine with it, starting the process described above, and potentially damaging a large part of the aluminium before it finally ends.

Aluminum coils play a crucial role in the production of furniture and fixtures, particularly in the manufacturing of lightweight and durable pieces. These coils are typically made from high-quality aluminum alloys, which offer excellent strength-to-weight ratios and corrosion resistance properties. One common application of aluminum coils in furniture production is in the creation of frames for chairs, tables, and other seating arrangements. The lightweight nature of aluminum makes it easier to handle and transport, while still providing the necessary structural integrity. Aluminum coils can be easily formed, welded, and assembled into various frame designs, allowing for flexibility in creating different furniture styles. Additionally, aluminum coils are often used in the production of fixtures such as cabinets, shelves, and display racks. These coils can be cut, shaped, and bent to create customized components that fit specific design requirements. The corrosion resistance of aluminum ensures that these fixtures can withstand exposure to moisture, making them suitable for both indoor and outdoor settings. Moreover, the use of aluminum coils in furniture and fixture manufacturing provides benefits beyond their physical properties. Aluminum is a highly recyclable material, making it an environmentally friendly choice. It also offers cost-effectiveness due to its durability and low maintenance requirements, reducing long-term expenses for both manufacturers and consumers. In summary, aluminum coils are integral to the production of furniture and fixtures due to their lightweight, durable, and corrosion-resistant properties. Their versatility allows for the creation of various designs, while their recyclability and cost-effectiveness make them a preferred choice in the industry.

To ensure the production of high-quality and defect-free aluminum coils, a variety of methods are employed to inspect for surface defects. Visual inspection is one commonly used technique, wherein trained inspectors carefully examine the entire surface of the coils for imperfections such as scratches, dents, or unevenness. This inspection takes place in optimal lighting conditions to ensure visibility and accuracy. In addition to visual inspection, more advanced techniques are utilized to detect subtle surface defects. An example of such a method is fluorescent penetrant inspection, where a fluorescent dye is applied to the coil surface. This dye seeps into any surface defects or cracks, and after a certain period of time, the excess dye is removed. The coil is then examined under ultraviolet light, which causes the dye to fluoresce, thereby making any defects easily visible. Another frequently used technique is eddy current testing, a non-destructive method that employs electromagnetic induction to identify defects like cracks or delaminations on the surface of aluminum coils. A probe is passed over the coil surface, and any variations in electrical conductivity caused by defects are detected and analyzed. Furthermore, automated systems equipped with high-resolution cameras and image-processing software can also be utilized for surface inspection. These systems capture detailed images of the coil surface, which are then analyzed by the software based on predefined criteria to identify any defects. This method ensures consistent and objective inspection results. Overall, thorough inspection procedures are implemented to detect and address any surface defects in aluminum coils before further processing or usage. These inspections are vital in maintaining product quality, adhering to industry standards, and ensuring customer satisfaction.

I know when you stick weld aluminum you're more brazing than actually welding but i was just wondering about this, i want some electrodes just in case i need a temporary repair. Also what Amperage should i run it at,and what polarity?? my friend told me to run hotter than usual but hes only 14, and I dont know how reliable he is. Im 14 by the way also and have been welding for two years now and im always out running around the ranch doing small repairs. thanks ahead of time!

Aluminum will oxidize quickly when it is heated in the air. You must have an inert gas around the weld when you are working it. A wire feed or T I G system is better than a stick machine. I suggest you do a lot of reading about aluminum and how to it is welded before you buy any tools. For small repairs that do not require much strength J B Weld will work.

Various products can be created from aluminum coils by undergoing a series of steps for further fabrication. To begin, the coil is typically uncoiled to separate it into individual sheets or strips, which can be done manually or through automation. Next, the coils are cleaned to eliminate dirt, oil, or other contaminants. This step is crucial to ensure proper adhesion and surface finish in subsequent fabrication processes. The cleaning process may involve chemical treatments, rinsing, or mechanical brushing. Following the cleaning process, the coils often go through a pre-treatment stage, such as chemical conversion coating or anodizing. These treatments enhance the surface properties of the aluminum, providing improved corrosion resistance, better adhesion for coatings, and enhanced paint adhesion. Once the pre-treatment is finished, the coils are prepared for fabrication. This can be accomplished through various techniques, such as cutting, bending, stamping, or roll forming. Cutting can be performed using shearing, sawing, or laser cutting techniques, depending on the desired dimensions and accuracy. Bending and forming are commonly utilized to shape the aluminum coils into desired profiles or structures. This can be achieved through the use of press brakes, roll forming machines, or specialized bending equipment. Stamping is another popular method of fabrication, where the coils are pressed into specific shapes using dies and punches. This technique is commonly employed in the production of automotive parts, household appliances, and electronics. Upon completion of the desired fabrication, the coils may undergo additional surface treatments or coatings to provide protection or enhance their appearance. This can include painting, powder coating, or the application of protective films. In conclusion, aluminum coils undergo a series of steps including uncoiling, surface cleaning, pre-treatment, cutting, bending, stamping, and surface treatments to facilitate further fabrication. These processes enable the transformation of the coils into various products with the desired properties and characteristics.
