6061 T651 Aluminum Sheet Overview
6061 T651 aluminum sheet is one of the most widely used aluminum materials due to its excellent combination of high strength, light weight, good formability, and strong resistance to moisture, heat, and corrosion. With an ultimate tensile strength of no less than 42,000 psi and a yield strength of at least 35,000 psi, 6061 aluminum sheet is suitable for a broad range of structural and industrial applications. Among all aluminum grades, 6061 aluminum alloy remains the most popular choice worldwide.
At GNEE, we supply high-quality 6061 T651 aluminum sheets that meet strict industrial standards and are widely trusted across multiple sectors.
6061 Aluminum Sheet vs 6063 Aluminum Sheet
6063 aluminum alloy is commonly manufactured as 6063 aluminum sheets and extruded profiles. Due to its excellent surface finish and extrudability, 6063 aluminum is widely used in architectural and decorative applications, such as building profiles, irrigation pipes, vehicles, gantries, furniture, elevators, fences, and similar products.
In comparison, 6061 aluminum alloy is mainly supplied as 6061 aluminum sheets and coils, typically in tempers such as T6, T4, and T651. With a hardness exceeding 95 Brinell, 6061 aluminum sheet is especially suitable for machining and load-bearing applications. Because of its higher mechanical strength, 6061 aluminum sheet is used more extensively than 6063 aluminum in industrial environments.
6061 Aluminum Sheet Applications
6061 aluminum alloy is well suited for applications that require high strength, good weldability, and excellent corrosion resistance. It is commonly used in:
Structural tubing and rods
Truck bodies and transportation components
Tower structures and industrial frameworks
Ships, trams, and marine equipment
Furniture and mechanical parts
Precision machining and CNC components
Thanks to its superior strength performance, 6061 aluminum sheet is preferred over 6063 aluminum sheet in demanding industrial and structural applications.
6061 T651 Aluminum Sheet Mechanical Properties
6061 T651 aluminum sheet is known for being strong, easily machined, and highly weldable. Compared with 6063 aluminum alloys, 6061 aluminum alloys offer nearly double the strength, making them more suitable for structural uses.
Key mechanical characteristics include:
Ultimate tensile strength: ≥ 42,000 psi (290 MPa)
Yield strength: ≥ 35,000 psi (241 MPa)
Elongation:
≥ 8% for thicknesses up to 0.250 inch (6.35 mm)
≥ 10% for thicker sections
The T651 temper provides mechanical properties similar to T6, while also offering improved stress relief through stretching, making it ideal for precision machining.
6061 Aluminum Sheet Historical and Industrial Significance
6061 aluminum alloy has a proven history in critical applications. One well-known example is the Pioneer plaque, which was manufactured using this specific aluminum alloy due to its durability and stability.
