6063 Aluminum Alloy offers a unique combination of dimensional stability and flatness that makes it ideal for CNC machining, tooling plates, fixture bases, and vacuum chucks. At Mingtai Aluminum, we specialize in supplying premium-grade Aluminum 6063 T651 Plates designed for industries ranging from aerospace and medical devices to semiconductor equipment and high-end consumer electronics.
What Is 6063 Aluminum Alloy?
6063 aluminum is widely known as an architectural alloy, commonly used for extrusions such as window frames and railings. However, in its T651 temper and precision cast plate form, 6063 becomes an entirely different material—one that is highly favored for precision machining applications.
Key characteristics of 6063 aluminum include:
Excellent surface finish quality
Good corrosion resistance
Superior anodizing response
Moderate strength with excellent machinability

Why Choose Ultra Flat Aluminum 6063 T651 Plates?
Exceptional Flatness Tolerances
Our high precision ultra flat aluminum 6063 T651 plates are produced with flatness specifications as tight as 0.1 mm per square meter. This level of precision ensures that your finished components remain stable and true, reducing secondary operations and material waste.
Stress-Relieved T651 Temper
The T651 temper indicates that the material has been solution heat-treated and then artificially aged, followed by stress-relieving stretching. This process minimizes internal residual stresses, allowing for excellent stability during high-speed machining—even after significant material removal.
Superior Surface Quality
Ultra flat 6063 plates are typically offered with a polished or mill finish that requires minimal surface preparation. The fine grain structure also yields outstanding results after anodizing, making it a top choice for visible components in electronics and medical devices.
