The purest chemical element aluminum is soft, malleable, non-magnetic, and silver-white. However, this element is not only used in pure form. Aluminum usually forms alloys with various elements (such as manganese, copper, and magnesium), forming hundreds of aluminum alloys with significantly improved properties.

Aluminum alloy precision parts have high strength, good plasticity, excellent conductivity, thermal conductivity, and corrosion resistance, and can obtain good mechanical properties, physical properties, and corrosion resistance through heat treatment. The processing of aluminum alloy parts is to process aluminum through lathes and CNC computers, and carry out subsequent processing such as sandblasting, polishing, wiredrawing, electroplating, spraying, anodizing, laser engraving, etc. as required. The appearance of aluminum alloy parts is full of unique metal texture, lightweight, and strong heat dissipation, which are favored by various industries.

Advantages of aluminum alloy CNC machining parts

Machinability

Aluminum can be easily formed, processed, and machined through various processes. Because it is soft and easy to break, it can be cut quickly and easily with machine tools. It is also cheaper than steel and requires less electricity. These functions are of great benefit to mechanics and customers who order parts. In addition, the good machinability of aluminum means that the deformation of aluminum in the processing process is small. This will lead to higher accuracy because it allows CNC machines to obtain higher tolerances.

Strength

Aluminum parts have a high strength-to-weight ratio. The density of aluminum is about one-third that of steel. The demand for aluminum parts has increased. The material has high strength but is lightweight. These two characteristics make it an ideal choice for manufacturing key components in the automotive and aerospace industries.

However, different grades of aluminum have different uses. Due to its good strength-to-weight ratio, general-purpose products such as 6061 can be used for various parts. It is worth noting that high-strength products such as 7075 may be the first choice for aerospace and marine applications.

Corrosion resistance

Aluminum has scratch resistance and corrosion resistance under common marine and atmospheric conditions. You can enhance these properties by anodizing them. It should be noted that different grades of aluminum have different corrosion resistance.

Can withstand temperature changes

Steel and aluminum have been popular for several years. These metals have unique advantages, making them an ideal choice for various industrial applications. In terms of durability, steel is the most popular of the two materials. However, if temperature changes are involved, steel is not the right choice. For example, steel cannot withstand high welding temperatures or extremely low temperatures. However, aluminum can effectively withstand both situations. Aluminum can maintain its softness, ductility, and strength at extremely low temperatures.

Conductivity

At room temperature, the conductivity of pure aluminum is about 37.7 million Siemens per meter. Although the conductivity of aluminum alloys may be lower than that of pure aluminum, their conductivity is enough to make their parts find use in electrical components. On the other hand, if conductivity is not the ideal characteristic of machined parts, aluminum will be an unsuitable material.

Recyclability

Aluminum parts are easy to recycle, helping to increase their use in industrial applications. Therefore, CNC-processed aluminum parts are an ideal choice for companies seeking to reduce their carbon footprint. As we all know, CNC machining is subtractive machining, in which a large amount of material waste is generated due to a chip. Material waste can be recycled to produce better products.

Anodic oxidation potential

The anodizing process is usually carried out after machining, including passing a current through parts in an electrolytic acid bath, which is easy to achieve in aluminum. And produce aluminum sheets that are more resistant to physical impact and corrosion.

Highly customizable

Aluminum can be easily customized to meet typical application requirements. CNC machining parts can be beautified or trimmed to the required specifications. For example, they can be plated with colors including green, black, blue, or any other desired color.

With the more and more extensive application of aluminum alloy parts, the processing of aluminum alloy parts, especially the quality and efficiency of CNC processing, has also been paid more and more attention by processing manufacturers.

Searching for an aluminum precision machining, aluminum precision casting, aluminum precision die casting manufacturer from China, you can get high-quality products at a nice price.
