Application solutions of high-strength aluminum alloy in consumer electronic equipment and other fields

Driven by consumption upgrading, secondary consumption and diversified consumption of consumer electronic products have gradually become mainstream, and the market has entered a stable and rapid development stage. In this environment, consumer electronics enterprises pay more and more attention to product appearance design, materials, and processes to improve user experience and brand image. With the rapid development of the global consumer electronics market, the consumption of aluminum in the consumer electronics industry is increasing, especially with the growing demand for high-quality aluminum deep-processing products. CNC machining of aluminum parts can achieve high precision and high efficiency because it adopts a CNC system for automation control, which can complete a large number of machining tasks in a short period. Compared with traditional manual machining methods, CNC machining has higher precision, better quality of machined surfaces, and higher machining efficiency, significantly shortening the production cycle.

Given the future application and development needs of aluminum alloy machining technology for consumer electronic products, we focus on the in-depth application of aluminum alloy in the field of consumer electronics, open up communication channels between technology enterprises and brand manufacturers, and expand the application of aluminum in the consumer electronics market. The application of aluminum alloy in the appearance needs of consumer electronics products is becoming increasingly widespread.

With the rapid development of the consumer electronics market, the external packaging of various consumer electronics products is changing to aluminum alloy. This is because aluminum alloy costs are decreasing, and the products are light, environmentally friendly, practical, and beautiful.

Aluminum alloy is mainly embodied in consumer electronic products in the form of shells, frames, heat sinks, and aluminum tubes. The 5000-series and 6000-series are the most adopted aluminum alloy series. 7000-series aluminum alloys are mainly imported, and only a few companies, such as Apple, embrace them in high-end products. At present, the following alloy series are used primarily:

1.    Five series (especially magnesium) The main element of this series of aluminum plates is magnesium, containing magnesium between 3-5%. It can also be called an aluminum-magnesium alloy. The main features are low density, high tensile strength, and high elongation. It is widely used in conventional industry. Processing technology for continuous casting and rolling belongs to the hot-rolled aluminum plate series and can process deep oxidation. In our country, the 5000 series aluminum plate belongs to one of the more mature ones.

2. The Six series (mainly magnesium and silicon) contains two magnesium and silicon elements. It is a cold treatment of aluminum forging products suitable for high-application anti-corrosive oxidation requirements: good usability, excellent interface characteristics, easy coating, and good workability.

The 3.7 series (mainly zinc) contains zinc elements, is an aluminum-magnesium-zinc-copper alloy, is heat-treatable, belongs to the super-hard aluminum alloy, and has good wear resistance. The main feature is hardness; it requires high strength, corrosion resistance of high-stress structural parts, and mold manufacturing.

Aluminum Hex Nuts: One-third the weight of steel, these aluminum nuts are corrosion-resistant and nonmagnetic in wet environments. All meet ASME B18 dimensional standards.

Black corrosion-resistant coated aluminum nuts, also known as black luster nuts, are more corrosion-resistant than uncoated aluminum nuts.

They're Nylon-Insert Locknuts: One-third the weight of steel, aluminum nuts resist corrosion in wet environments and are nonmagnetic. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but they hold power with each use.

Aluminum Coupling Nuts: One-third the weight of steel, these aluminum coupling nuts are corrosion-resistant and nonmagnetic in wet environments. Also known as extension nuts, they are used to connect and extend threaded rods.

To improve the corrosion resistance, the surface of the aluminum alloy shell of the cell phone will do artificial anodic oxidation to make the appearance more beautiful and enhance the surface hardness. The anodic oxidation film's quality and adhesion directly affect the cell phone's appearance quality and corrosion phone's. Seven series aluminum alloy due to the high alloy composition. These alloying elements in the conventional melting and casting of aluminum rods make it challenging to avoid non-uniform distribution, producing bias polymerization, also known as macroscopic segregation. Part of the segregation will be partially improved in the subsequent homogenization treatment and extrusion of the aluminum row process, but it can not be eliminated. The existence of segregation means that the composition of each part of the material is not uniformly distributed. This uneven composition will cause the anodic oxide film quality and adhesion to be different, resulting in oxidation quickly appearing after the color difference and other appearance defects. The use of performance is not stable, and part of the position of the oxide film adhesion is not enough to fall off once the protection of the oxide film, coupled with hand sweat, humid air, and hot weather, accelerates corrosion.

With the advancement of science and technology, people cannot live, play, work, or work in an office without computers. Similarly, as one of the most abundant metals on earth, aluminum is used in aluminum application technology, computer mainframes, keyboards, mice, mouse pads, and innovations in aluminum applications. This is mainly based on the thermal properties of aluminum alloys and the simplicity of surface treatment.

Metallic materials are increasingly used in various products, such as laptops, cell phones, mobile solid-state drives, PSSDs, LED desk lamps, cameras, etc. The application of metal materials so that the product appears to be high-grade, texture, the embodiment of texture is the quality of the product such as metal-like stability, giving people a psychological sense of dignity, rather than a cheap feeling, more conducive to enhancing brand value.

Aluminum and aluminum alloys have easy processing, rich surface treatment, sound, visual effects, and other characteristics, and many products have applications. I once saw a video describing how the shell of an Apple laptop is machined from a block of aluminum alloy by CNC machining equipment and subjected to multiple surface treatments, which involves several significant processes, including CNC milling, polishing, high-gloss milling, wire drawing, and so on. The surface treatment for aluminum and aluminum alloy mainly includes milling/high-gloss cutting, sandblasting, polishing, brushing, anodizing, spraying, etc.

With the improvement of people's living standards and the development of information technology, more and more consumer electronic products are entering people's daily lives. Lightweight is the people's trend, and the application of high-strength aluminum alloy products is becoming increasingly widespread. We hope that our aluminum processing enterprises will actively support the R&D process of downstream enterprises so that more aluminum alloy materials can be applied to consumer electronics!
