Aluminum is a lightweight metal and is currently the most widely used metal material in precision manufacturing.

Aluminum alloys are used in a variety of industrial and manufacturing fields, including aerospace, automotive, construction, and packaging. It is widely used for its light weight, good electrical and thermal conductivity, high reflectivity, and oxidation resistance.

Aluminum is an ideal material for CNC machining shops because it is easy to machine and can produce precise parts quickly. CNC machining involves the use of computer-controlled machine tools to precisely cut, drill, and mill aluminum parts. This type of machining allows for complex designs and produces parts with tight tolerances and an excellent surface finish. The machinability of aluminum alloys directly affects machining speed and production efficiency.

Aluminum Alloys Commonly Used in CNC Machining

• 6061 aluminum: The main alloying elements of 6061 aluminum are magnesium (Mg) and silicon (Si). In terms of CNC machining, 6061 aluminum alloy is very suitable for applications that require precise dimensions and surface finish due to its excellent mechanical properties and processing performance. It has good processing performance and is easy to cut, mill and drill, so it is very popular in the manufacture of complex parts. Major uses include building structures, automotive parts, furniture, ships, musical instruments, etc;
• 7075 aluminum: The main alloying element of 7075 aluminum is zinc, and magnesium and copper are added at the same time. These elements form MgZn2 with significant strengthening effect, making the heat treatment effect of the alloy far better than that of aluminum-zinc binary alloy. It is widely used in aerospace, automobile, mold manufacturing, mechanical equipment, tooling and fixtures and other fields. Although the machinability of 7075 aluminum alloy is not as good as some other aluminum alloys, such as 6061, it can still be made into various precision parts through CNC machining.

Aluminum alloy is a material that adds a certain amount of other alloy elements to aluminum. In addition to the general properties of aluminum, aluminum alloy also has some specific properties of the alloy due to the different types and quantities of added alloy elements.

Aluminum Parts

There is a big difference between aluminum CNC turning parts and aluminum CNC milling parts. This is mainly due to the difference in turning and milling processes. The manufacturing process of CNC aluminum parts depends on the design of the parts themselves and the application environment. Our CNC experts will select the most cost-effective processing solution based on your requirements.

In addition, CNC machined aluminum parts usually need surface treatment to meet customer requirements. Currently, anodizing is the most common surface treatment method for aluminum parts. For more information, see anodizing aluminum parts.
