Hardness of 5052 aluminum plate Most people are mainly concerned about the hardness of aluminum materials, but in fact, hardness is not the main consideration factor for aluminum material selection. Generally speaking, there is a positive correlation between hardness and strength. Strength Usually refers to tensile strength, which is a key factor to consider when applying aluminum materials. Insufficient strength can cause deformation and failure of parts, leading to malfunctions. Pure aluminum is the softest and has the lowest strength, while heat treated alloys of the 2 and 7 series have the highest strength. Each alloy has significant differences in strength due to different states, so when selecting alloy strength, …

Pinhole Pinhole is the main defect of aluminum foil. In the raw material, the dust on the roll, rolled oil, and even in the air reaches 6μm both the left and right into the roller seam will cause pinholes, so it is impossible for 6 μ m aluminum foil without pinholes, and we can only evaluate the size and size of it. Of course, using alloying and other means to improve the hardening properties of materials can also help to reduce pinholes. High quality hot rolled rolled 6 μ m aluminum foil pinholes can be under 100 / ㎡. When the casting and rolling material is well purified, the 6 μ …

Development of aluminum foil packaging The development of aluminum foil packaging Aluminum foil packaging began in the early 20th century, when aluminum foil was used as an expensive packaging material, only for high-grade packaging. In 1911, Swiss confectionery companies began to pack chocolate with aluminum foil, gradually replacing tin foil. In 1913, the United States also began to produce aluminum foil based on the success of aluminum smelting, mainly used for high-end goods, life-saving products and chewing gum packaging. In 1921, the United States successfully developed composite aluminum foil board, which was mainly used as decorative board and advanced packaging folding carton. In 1938, hot-sealed aluminum foil was introduced. During …

Non-coated aluminum foil Non-coated aluminum foil is a rolled foil annealed without any form of treatment. China 10 years ago, foreign about 15 years ago for air conditioning heat exchange sheet of aluminum foil are non-coated foil. Even at present, about 50% of the heat exchanger tablets used in foreign developed countries are still non-coated foil, while in China, this rate is about 60%. Coated aluminum foil The so-called coated aluminum foil is the surface retreatment of non-coated foil, so that it has some special function. In Japan, Germany and other countries with rapid technology development, the use of coated foil has been used for more than 15 years. In China, …

Aluminum foil processing process is the aluminum product with the most processing processes, the smallest thickness and the greatest difficulty in the aluminum processing industry. At present, there are two common processing routes in the industry: (1) ingot hot rolling method; (2) double roll rolling method.(1)Ingot hot rolling method: first aluminum melt cast into flat ingot, and then after homogenization, hot rolling, cold rolling, intermediate annealing and other processes, continue to cold rolling into a thickness of about 0.4~1.0mm as foil billet (casting hot rolled billet cold rolled foil rolling). (2)Double roll rolling method: compared with the ingot hot rolling method, the process of producing aluminum foil billet is relatively …

First of all, according to the thickness, aluminum foil can be divided into double zero foil, single zero foil and thick foil. Double zero foil refers to the foil with two zero (thickness <0.01mm). When the thickness is mm, single zero foil with one zero (0.01mm thickness <0.1mm); thick foil refers to the aluminum foil with thickness between 0.1mm and 0.2mm. Different terminal applications will have different thickness requirements. Generally speaking, double zero foil is mainly used for food packaging, cigarette packaging, electronic foil, etc.; single zero foil is used for some food packaging, drug packaging, electronic circuit signal shielding, air conditioning foil, etc.; thick foil is mainly used for …

It is very important to maintain drug quality and safety when it is packaged. Advantages of aluminum foil Good barrier performance: aluminum foil can effectively prevent drugs from the moisture and humidity, because it is an impermeable material, which can maintain the dryness and stability of drugs. In addition, tin foil can prevent oxygen and other gases from entering the drug packaging, thus maintaining the stability and active ingredients of the drug. Some medicines deteriorate when in contact with oxygen, so aluminum foil can help protect their quality. Good thermal insulation: Aluminum foil is an excellent thermal insulation material that can help maintain the active ingredients and efficacy of drugs. …
