　　III. Strategic Material Selection: Matching Materials to Performance Requirements

　　(A) Alloy Steels

　　Alloy steels are widely used in CNC turning parts due to their high strength, toughness, and wear resistance. They contain alloying elements such as chromium, nickel, molybdenum, and vanadium, which enhance their mechanical properties. For example, 4140 alloy steel, with its good combination of strength and hardenability, is commonly used for parts like shafts, axles, and gears in industrial machinery and automotive applications. Its ability to withstand high torque and bending forces makes it a reliable choice for components that are subject to heavy loads and dynamic stresses.

　　(B) Aluminum Alloys

　　Aluminum alloys are highly valued for their lightweight properties, excellent formability, and good corrosion resistance. Alloys such as 6061 – T6 and 7075 – T6 are commonly used in aerospace, automotive, and electronics industries. 6061 – T6 offers a good balance of strength, corrosion resistance, and machinability, making it suitable for a variety of applications, from structural components to consumer products. 7075 – T6, on the other hand, is a high – strength alloy often used in applications where maximum strength – to – weight ratio is required, such as in aircraft structures and high – performance automotive parts. In CNC turning, aluminum alloys can be machined quickly and accurately, allowing for the production of lightweight yet strong components.

　　Stainless steels are preferred for applications where corrosion resistance is crucial. They contain chromium, which forms a passive oxide layer on the surface, protecting the material from rust and chemical attack. 304 stainless steel, with its good corrosion resistance and formability, is suitable for a wide range of applications, including food processing equipment, medical devices, and general industrial components. For more aggressive environments, 316 stainless steel, which contains molybdenum for enhanced corrosion resistance, is often the material of choice. CNC turning of stainless steel parts requires specialized tools and machining strategies to prevent work – hardening and ensure a smooth surface finish.
