What are the advantages of aluminum alloy CNC machining precision parts

Aluminum, the purest chemical element, is soft, malleable, nonmagnetic, and silvery white. However, this element is not only used in its pure form. Aluminum is often alloyed with various elements such as manganese, copper and magnesium to form hundreds of aluminum alloys with significantly improved properties.

It has high strength, good plasticity, excellent electrical 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, wire drawing, electroplating, spraying, anodizing, and laser engraving as required. The appearance of aluminum alloy parts is full of unique metal texture, light weight, strong heat dissipation, and is favored by various industries.

Now, it is obvious how cnc aluminum alloy parts are different from other metal parts. This article discusses some of the advantages of aluminum alloy CNC machined parts.

Machinability

Aluminum can be easily formed, processed and machined by various processes. Because it is soft and brittle, it can be cut quickly and easily with a machine tool. It is also cheaper and requires less electricity than steel. These features are of great benefit to mechanics and customers ordering parts. Additionally, aluminum's good machinability means that aluminum deforms less during machining. This results in greater precision as it allows CNC machines to achieve higher tolerances.

Intensity

Aluminum parts have a high strength-to-weight ratio. Aluminum is about one-third as dense as steel. The demand for aluminum parts has increased. The material is strong, yet lightweight. These two properties make it ideal for manufacturing critical components in the automotive and aerospace industries.

However, different grades of aluminum serve different purposes. General-purpose products such as 6061 can be used in a variety of parts due to their good strength-to-weight ratio, and it is worth noting that high-strength products such as 7075 may be the first choice for aerospace and marine applications.

Corrosion resistance

Aluminum is scratch and corrosion resistant under common marine and atmospheric conditions. You can enhance these properties with anodizing. It should be noted that different grades of aluminum have different corrosion resistance properties. For example, grades 6061 and 7475 are known to have excellent corrosion resistance.

Can withstand temperature changes

Steel and aluminum have been popular for several years. These metals have unique advantages that make them ideal for a variety of industrial applications. Steel is the most popular of the two materials when it comes to durability. 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 conditions. Aluminum retains 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 aluminum alloys may have lower electrical conductivity than pure aluminum, they are sufficiently conductive for their parts to find use in electrical components. On the other hand, aluminum would be an unsuitable material if electrical conductivity was not a desirable characteristic for the machined part.

Recyclability

Aluminum parts are easy to recycle, helping to increase their use in industrial applications. As such, CNC machined aluminum parts are ideal for companies looking to reduce their carbon footprint. As we all know, CNC machining is a subtractive machining in which a lot of material waste is generated due to chips. Material waste can be recycled to produce better products.

Anodic oxidation potential

The anodizing process, usually performed after machining is complete, involves passing an electric current through the part in an electrolytic acid bath, which is easily accomplished in aluminum. And produce aluminum sheets that are more resistant to physical shock and corrosion.

Highly customizable

Aluminum can be easily customized to meet typical application requirements. CNC machined parts can be embellished or trimmed to desired specifications. For example, they can be plated in colors including green, black, blue or any other desired color.

As the application of aluminum alloy parts becomes more and more extensive, the processing of aluminum alloy parts, especially the quality and efficiency of CNC processing, is also more and more valued by processing manufacturers.
