6061 aluminum: Strength: It has higher tensile strength and is generally stronger than 6063 aluminum. Machinability: It has good machinability, making it easier to work with for various applications. Structural applications: Due to its strength, 6061 is commonly used in structural components, such as frames, aircraft parts, and automotive parts. Heat treatable: 6061 aluminum can be heat treated, which further enhances its mechanical properties.
6063 aluminum: Extrusion: It is primarily known for its excellent extrudability, meaning it can be easily shaped into complex profiles. Aesthetics: 6063 is often preferred for aesthetic applications because it has a smooth and shiny surface finish. Moderate strength: Although not as strong as 6061 aluminum, 6063 still offers sufficient strength for many applications. Architectural applications: It is commonly used in architectural applications like window frames, doors, and trim.
Ultimately, the choice between 6061 and 6063 aluminum will depend on the specific requirements of your project or application. It's advisable to consult with an engineer or metallurgist to determine the most suitable alloy for your needs.
