Name a common material used in precision machining.

Aluminum is widely utilized in precision machining due to its favorable properties. It is lightweight, which makes it easier to handle and reduces the overall weight of the final product. Aluminum also has excellent machinability, allowing for efficient cutting and shaping during the machining process. Its ability to resist corrosion enhances durability, making it suitable for a variety of applications, including aerospace, automotive, and consumer goods. Furthermore, aluminum can be easily anodized for added surface protection or aesthetic appeal, making it a versatile choice for machinists. The combination of these characteristics makes aluminum a common material in precision machining.
