CNC machinable aluminum alloys are aluminum alloys that are ideally suited for processing using computer numerical control (CNC) machines. These alloys have specific properties that make them easier to process, thereby increasing the efficiency and precision of the manufacturing process.
Some commonly used CNC machined aluminum alloys include:
6061 aluminum alloy: This alloy is one of the most widely used and versatile aluminum alloys. It has good machinability, excellent weldability and high strength. It is commonly used in a variety of applications, including aerospace components, automotive components, and consumer products.
7075 Aluminum Alloy: Known for its high strength-to-weight ratio, 7075 aluminum alloy is often used in applications where strength and durability are critical, such as aerospace, military and high-performance sports equipment. While it may be more challenging to machine than other aluminum alloys, it is still considered amenable to CNC machining with the proper tools and techniques.
2024 Aluminum Alloy: This alloy is known for its high strength and good machinability. It is commonly used in aerospace applications, including aircraft structures and components.
6063 aluminum alloy: 6063 aluminum alloy is mainly used in the extrusion process and has good machinability and excellent corrosion resistance. It is often used in architectural applications such as window frames and trim.
These are just a few examples of aluminum alloys that can be machined by CNC. The choice of alloy depends on the specific requirements of the application, such as required mechanical properties, corrosion resistance and machinability characteristics.
