What's the difference between aluminum part and anodized aluminum part?

“CNC aluminum machined parts”, refer to components or products made from aluminum using computer numerical control (CNC) machining processes. CNC machining is a manufacturing method where pre-programmed computer software is used to control the movement of machine tools to cut, drill, and shape raw material (in this case, aluminum) into the desired final product.

The difference between regular aluminum part and anodized aluminum part lies in the surface treatment.

Aluminum: Aluminum is a lightweight metal known for its excellent strength-to-weight ratio, corrosion resistance, and conductivity. When left untreated, aluminum has a natural oxide layer that provides some level of protection against corrosion. However, in certain environments, it may be prone to surface discoloration and wear over time.

Anodized Aluminum: Anodizing is an electrochemical process that enhances the properties of aluminum by forming a thicker and more durable oxide layer on its surface. This oxide layer is integral to the metal and offers improved corrosion resistance, increased hardness, and enhanced wear resistance. Anodized aluminum also allows for a wide range of color options and can provide a more aesthetically pleasing finish compared to bare aluminum.

In the context of "CNC aluminum machined parts," the choice between regular aluminum and anodized aluminum depends on the specific requirements of the application. If the parts need better corrosion resistance, wear resistance, or a specific color finish, anodized aluminum may be preferred. On the other hand, if those characteristics are not crucial, regular aluminum might suffice, offering a cost-effective solution for certain applications.
