The advantages of CNC aluminum turning, which include machinability, strength-to-weight ratio, corrosion resistance, adaptability, accuracy, precision, and consistency, make it a widely used manufacturing technique. The automotive, aerospace, electronics, and construction industries all frequently employ aluminum because it is a strong, lightweight metal that resists corrosion. In addition, aluminum is a reasonably priced metal, making it a sensible option for a variety of uses. The following aluminum alloys are suitable for CNC turning:

• 2000 series: These alloys are well recognized for their extreme hardness and strength. They are frequently employed in industries like aircraft and automobile parts, where strength and durability are crucial.
• 6000 series: These alloys are renowned for their excellent machinability and resistance to corrosion. They are frequently utilized for applications like electronic components and structural components where a good blend of strength, machinability, and corrosion resistance is necessary
• 7000 series: These alloys are renowned for their extraordinarily high hardness and strength. They are frequently utilized for things like aircraft parts and military gear where the highest levels of toughness and longevity are necessary.

Specific examples of aluminum alloys that are commonly used for CNC turning include:

• 2014: This alloy is renowned for its extreme hardness and strength. It is frequently employed in applications requiring great strength, such as automotive and aerospace parts.
• 6061:This alloy is renowned for its excellent machinability and resistance to corrosion. It is frequently used for applications like electronic components and structural components where a good balance of strength, machinability, and corrosion resistance is necessary.
• 7075: This alloy has a very high strength and hardness rating. It is frequently utilized in situations requiring the utmost strength and durability, like aerospace parts and military hardware.

Depending on the particular needs of the application, the appropriate aluminum alloy for CNC turning will be chosen. For instance, an alloy from the 2000 or 7000 family would be the ideal option if strength is the most crucial component. An alloy from the 6000 family may be the ideal option if machinability is the most crucial aspect.

It is significant to remember that not every aluminum alloy is the same. While some alloys are more prone to corrosion than others, some alloys are more challenging to machine. It is crucial to select an alloy that is appropriate for the application's unique requirements.
