HAOMEI Aluminum produces a wide range of 6063 aluminum sheets, including O, T4, T5, and T6 tempers in various thicknesses. Laser cutting services and highly competitive wholesale prices are available.
6063 aluminum sheet is a heat-treatable Al-Mg-Si alloy in the 6000 series. With a well-balanced and relatively mild alloy composition, it has moderate strength compared with 6061 aluminum sheet and is more suitable for forming processes and decorative surface finishing.
It contains no harmful impurities, is clean and environmentally friendly, and can be fully recycled.
As a 6000 series aluminum alloy, 6063 aluminum sheet offers excellent processability, weldability, extrudability, electroplating performance, corrosion resistance, and toughness. It is easy to polish, apply protective film to, and anodize. Its anodized finish is particularly attractive.
T6 is the most commonly used temper, while T4 temper provides better formability. 6063 aluminum sheet has been widely used worldwide in industrial manufacturing, architectural decoration, electronic equipment, and transportation applications.

Good Weldability: 6063 aluminum sheet can be welded using TIG welding, MIG welding, and other methods. It provides stable welded structures and is suitable for frames, brackets, enclosures, connectors, and related products.
Good Corrosion Resistance: 6063 aluminum sheet has good oxidation resistance and corrosion resistance. It can maintain stable performance in both indoor and outdoor environments. After anodizing, its weather resistance and wear resistance are further improved.
Excellent Surface Finish for Anodizing: One of the main advantages of 6063 aluminum sheet is its excellent surface-treatment capability. Processes such as anodizing, sandblasting, brushing, and coating can produce a delicate, uniform, and visually appealing finish. It is ideal for decorative products and applications with high appearance requirements.
Excellent Processing Performance: It is easy to cut, bend, stamp, drill, mill, and weld. It supports a wide range of fabrication methods and can meet the production requirements of various structural and appearance components.
Lightweight with Moderate Strength: 6063 aluminum sheet has a low density and light weight. While maintaining sufficient strength, it supports lightweight product design and helps reduce transportation, installation, and operating costs.
| Temper | Characteristics | Typical Use |
| O | Extremely soft with high ductility; ideal for deep drawing and complex bending/forming | Deep-drawn and highly formed parts |
| T4 | Moderate strength with good toughness; a preferred choice for general fabrication | General processing and formed products |
| T5 | Artificially aged with moderate hardness; commonly used for structural support | Structural support components |
| T6 | Higher hardness and good flatness; suitable for precision sheet applications | Precision panels and higher-strength parts |
| T651 | T6 temper with stretch stress relief; minimizes internal stress | Precision machining, such as CNC engraving and machining of thin sheets |
6063 aluminum sheet can undergo a variety of secondary processing methods:
Cutting: Saw cutting, laser cutting, waterjet cutting, etc.
Machining: CNC machining, milling, drilling, tapping, etc.
Forming: Bending, stamping, stretching, rolling, etc.
