Aluminum Alloy CNC Machining in Electronic Industry

The application of aluminum alloy parts is more and more extensive, which puts forward higher requirements for CNC machining processing technology. The aluminum alloy CNC precision parts machining industry has entered a new era of rapid development. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, chemical industry and daily life. Aluminum is very strong, making it an ideal material for mechanical parts, and its oxidized outer layer can resist element corrosion. These advantages make aluminum parts common in all industries.

There are always many advantages of aluminum alloy CNC processing

.

1. Easy to process

.
One of the main reasons for engineers to choose aluminum alloy cnc machining parts is that it is very simple and the materials are easy to process. Although this seems to be more beneficial to the machinists who make the parts, it is also very beneficial to the companies that order the parts and the end users who end up using it.

Because aluminum alloy is easy to be chipped and formed, it can be cut quickly and accurately with CNC machine tools. This is more important: First, CNC processing cycle is short, and product processing is cheaper (because less labor requires machinists, and less machine processing time). Secondly, good cutting performance means that when the tool passes through the workpiece, the deformation of the workpiece is very small. This allows the machine to meet tighter tolerances (down to ± 0.015 mm), resulting in higher accuracy and repeatability.

2. Corrosion resistance

.
Different grades of aluminum alloy materials have great differences in corrosion resistance, oxidation resistance and chemical destruction. Fortunately, some of the most popular cnc machined aluminum alloy part grades are the most wear-resistant.

3. Strength weight ratio.

Aluminum alloy has ideal physical properties, making it an ideal material for mechanical and appearance parts. The most important two points are the high strength and light weight of this metal. These two factors enable this material to be used in the manufacture of critical components, such as those required by the aerospace and automotive industries.

However, different grades of aluminum alloy materials have different uses. Due to its good strength to weight ratio, general brands such as 6061 can be used for various components, while high strength brands such as 7075 may be more suitable for aerospace and marine applications.

4. Conductivity.

Cnc machining parts can be used for electrical components because of their conductivity. Although the conductivity is not as good as that of copper, the conductivity of pure aluminum at room temperature is about 37.7 million Siemens/m. The conductivity of the alloy may be low, but the conductivity of aluminum is significantly higher than that of stainless steel and other materials.

5. Anodic oxidation potential.

Aluminum alloy cnc machined parts are particularly popular in the consumer electronics industry, not only because of strength and weight requirements, but also because of important aesthetic considerations. In addition to being easy to accept paint and coloring, aluminum alloy can also be anodized, which is a surface treatment process that can thicken the protection and oxidation outer layer of parts.

The anodizing process is usually carried out after machining, including energizing in the electrolytic acid bath to obtain aluminum plates that are more resistant to physical impact and corrosion.

Importantly, anodizing is easier to add color to mechanical aluminum alloy parts because the outer layer of anodizing is highly porous. The dye can pass through the porous part of the outer layer, and because they are embedded in the outer side of the hard metal part, they are unlikely to crack or peel off.

6. Recyclability

.
Another advantage of aluminum alloy CNC machining parts is its high recyclability, which makes it more suitable for companies seeking to minimize environmental impact, or companies only want to reduce material waste and recover part of the cost. Recyclable materials are particularly important in cnc machining, because in cnc machining, the chip on the tool will produce a large waste.

7.Heat dissipation.

Radiator is a widely used electronic device, which can transfer heat from electronic components to liquid coolant or air. Radiators are used in computers and other equipment to cool critical components to maintain normal function.

Machinable metals such as aluminum or copper are used, and the radiator can be manufactured with CNC processing technology. Precision CNC machine tools can even manufacture very small radiators, and can produce various configurations of equipment according to requirements.

Why aluminum alloy cnc processing is very popular in the electronic industry.

Based on the process exploration of “appearance” and “performance”, the aluminum alloy shell of smart phones, smart TV frames, smart watches and other aluminum alloy surfaces, tablet computers and other smart wearable devices can all use high-quality aluminum alloy materials to make products lighter, more environmentally friendly, more practical and more beautiful. Because aluminum alloy materials have the strength of metal, light weight, easy heat dissipation, and strong compression resistance. With the development of consumer electronics products, consumer electronics enterprises pay more and more attention to product design and material technology., In order to enhance the brand image and user experience, the application potential of aluminum in the electronic industry has been constantly tapped. Aluminum alloy is mainly embodied in shell, frames and anywhere else.

Consumer Electronics

.

Apple MacBook and its various models (MacBook Pro, MacBook Air) are one of the most famous consumer electronic products in the world. Its durable aluminum body is made of cnc milling technology.

Although die-casting is a widely used process for manufacturing these shells, cnc machining is rapidly becoming a more reliable and preferred method. They can produce more complex geometries, achieve tighter tolerances, and provide higher strength than die-casting and injection molding.

Apple relies heavily on CNC processing to make integrated enclosures for iPhones, iPads and MacBooks. The MacBook shell is carved from the extruded aluminum block using a CNC machine. The keyboard hole and the “thumb spoon” (the circular groove that can open the display cover) are also made with a CNC milling machine.

Aluminum alloy cnc processing is widely used in consumer electronic products, from mobile phones, headphones, speakers, watches, to televisions, laptops and even various smart homes. With the continuous growth of economy, the global demand for electronic communication and other products will also continue to grow, which will also promote the expansion of the application scope of aluminum in various subdivisions, and gradually develop towards high-end and specialization.CNC proto lab offer high quality aluminum alloy parts produced by CNC Machining.
