The sublimation aluminum sheet, aluminum circle sheet, 16 gauge aluminum sheet and offset printing plates have been pursued by many customers. Learn more. Sublimation Aluminum Sheet The brushed aluminum is a manufacturing process where lines are repeatedly scraped out of aluminum using sandpaper. In the process of processing the aluminum plate under pressure, the aluminum plate is forced through the mold under the action of external force, the metal cross-sectional area is compressed and the required cross-sectional area shape and size is obtained. 1xxx pure aluminum is one of the commonly used aluminum sheet for making brushed aluminum sheets wholesale. It is also one of the most commonly used raw materials in industrial production. It has good electrical conductivity, good welding performance, corrosion resistance, and low strength. 3xxx Al-Mn alloy has good corrosion resistance, good welding performance, and good plasticity. It cannot be strengthened by heat treatment, but its strength can be improved through cold work hardening. The main alloy grades are 3003, 3004 and 3105. 5xxx aluminum alloys are one of the mature aluminum series. It has low density, so its weight is lower than other series under the same area. It has good tensile strength, 1

The strength can only be improved by cold working. The brushed aluminum sheet can be one of the choice for sublimation. Dye-sublimation is the process of directly penetrating the pattern on the transfer paper into the material to be printed. Dye-sublimation requires the use of special dye-sublimation transfer photo paper. The advantage of sublimation over thermal transfer is that it has a high transfer rate and is not easy to fade. Haomei Aluminum can provide sublimation aluminum sheet with a thickness of 0.2-1.0 mm and more than 30 different colors. The main colors are glossy silver, glossy gold, glossy copper and glossy champagne, brushed silver, brushed gold, brushed copper and brushed stainless steel, titanium silver and titanium gold, pearlescent silver, pearlescent gold and pearlescent white, mirror silver, mirror gold and mirror champagne, high-gloss white and matte white, double-sided bright silver, flash silver, etc. The surface of our aluminum sheets is clean and perfect and has high thermal transfer rate. Aluminum Circle Sheet In terms of aluminum circles itself, how should you choose a aluminum discs circle? 2

Physical and chemical properties Aluminum circle sheet should have good thermal conductivity, electrical conductivity and good corrosion resistance. At the same time, related properties such as the strength, hardness and toughness of the material also need to be considered. Different processing techniques require different performance requirements for aluminum discs. 2. Purity and composition Generally speaking, aluminum discs with higher purity have better electrical and thermal conductivity. High-purity aluminum discs have good corrosion resistance and are suitable for use in corrosive environments. At the same time, attention should also be paid to the additional elements of aluminum discs, such as magnesium, manganese, etc. Their content has a certain impact on the performance of the material. 3. Strength and toughness When selecting a material, its balance of strength and toughness needs to be considered. Generally speaking, there is a certain antagonistic relationship between strength and toughness, that is, the stronger the material, the relatively poor 3

In practical applications, it is necessary to select the appropriate aluminum round sheet according to the specific situation to meet the use requirements after processing. 4. Processing performance Processing properties include plasticity, weldability, machinability, etc. During the processing, aluminum discs need to undergo shearing, stamping, welding and other processes. Therefore, aluminum circles with good processing properties need to be selected to ensure the smooth progress of the process. 5. Surface treatment Surface treatment can improve the corrosion resistance, oxidation resistance and surface finish of aluminum discs. Common surface treatment methods include anodizing, electroplating, spraying, etc. When selecting materials, you need to consider the need for surface treatment and choose the corresponding material. 6. Aluminum round blanks thickness and size The thickness selection of aluminum discs is determined based on specific usage requirements. The first thing to consider is the mechanical performance requirements of aluminum wafers. Aluminum discs of different thicknesses have different mechanical properties such as load-bearing capacity and strength. If the application needs to bear larger loads or has higher tensile strength requirements, thicker aluminum discs will be selected to meet these requirements. If it is for decoration or thermal conduction, then you can choose thinner aluminum discs. For road signs, large size aluminum circles are often chosen like 24 aluminum disc. For cookware or small household appliances, small size aluminum disc circles are chosen. 16 Gauge and 28 Gauge Aluminum Sheet Ga. Is the abbreviation of gauge. It is a length measurement unit for diameter originating in North America and belongs to the Brown & Sharpe measurement system. It was originally used in the fields of medicine and jewelry. The larger the 4

5. More information at https://www.alumhm.com/ Email: dolly@alumhm.com number, the smaller the diameter. Later, it was also popularized to express thickness. Since the Ga. Base and inches are different, there is no conversion formula. 16 gauge aluminum thickness is 0.0508 inch, that is 1.29032mm. 28 gauge aluminum sheet is 0.0126 inch, that is 0.32004 mm. The thickness of the aluminum sheet is linked to the price. Usually the aluminum sheet price with a thickness of 0.8-6.0mm is the lowest. The price of the aluminum plate thinner or thicker than this thickness is slightly higher, mainly because the thin one requires more rolling mill processing, while the thick one requires a hot rolling mill. Generally, the thickness of aluminum tread plate is between 0.8mm and 20mm. Common thicknesses are 1.0mm, 1.2mm, 1.5mm, 2.0mm, etc. Patterned aluminum plates of different thicknesses have different strengths and stiffnesses and can meet the needs of different projects. In addition to their own high requirements on performance, the thin aluminum sheets like 16 gauge aluminum sheet also has high requirements on the surface quality. There are clear requirements and regulations for surface defects such as sticking, scratches, marks, pine branch patterns, metal and non-metal press-in, oil stains, 5

In many cases, aluminum bottle cap materials are superior to traditional bottle caps such as natural or synthetic corks due to their excellent barrier and sealing properties in various types of wine, liquor and distilled spirits. In addition to the wide variety of diameters and sizes, the high caps made of aluminum alloy sheet provide sufficient space for cap printing and bring more product marketing possibilities to manufacturers. The alloys are 1100, 8011, 3003, 3105 and 5052. 8011 and 8011A are more common. Offset Printing CTP Plate Offset printing is a common printing technique in which an inked image is transferred from a printing plate to a blanket and then to the printing surface. Specifically, the printing plate must be able to transfer the image to paper or other substrate. Printing plates are usually made from aluminum printing sheets. There are mainly two types: offset printing ctp plate and PS plate. 6

However, judging from the development in the past two years, commercial printing companies, especially those that pursue printing quality, have become the protagonists of CTP applications. In terms of the CTP printing process, because the layout information of the publication is directly output to the printing plate, compared with PS printing, the film output link and PS plate printing link are reduced, so the cost of the CTP printing link includes: Output digital sample printing fee, printing fee (CTP plate making fee), and printing fee. Commercial and packaging printing companies that have high requirements for print quality mainly undertake printing tasks such as high-end quality albums and exquisite packaging products, all choose thermal CTP plate. Thermal CTP is characterized by using a laser with a wavelength of 830nm or 1064nm to record the printing plate. Violet CTP technology uses high-sensitivity violet printing plates specially produced for it. The grain of violet printing plats is finer than that of traditional plates, and the coating process is more complex. Of course, the photosensitive layer is also different from traditional PS plates. After development in recent years, it has become the three 7

The thickness of the aluminum sheet for CTP plates is generally 0.280mm, which is slightly thicker than the currently produced PS plates (the thickness of the PS plate base is 0.270mm±0.005mm). Some foreign companies also use 0.275mm thick aluminum plate base, and the thickness tolerance is ±0.005mm. If the aluminum plate base is thicker, the printing plate for sale will be stiffer and less likely to bend. 8
