6082 T651 Aluminum Composition and Properties

6082-T651 aluminum alloy belongs to the 6 series of aluminum alloys, with silicon (Si) and magnesium (Mg) as the primary alloying elements. This alloy is widely used in the aluminum alloy family due to its excellent overall performance, offering superior strength, corrosion resistance, and good welding characteristics. Especially in the T651 condition, it exhibits higher stability and stress resistance compared to other conditions (such as T6).

6082 T651 Aluminum Processing

• Solution Heat Treatment: First, the 6082 aluminum alloy is heated to a specific temperature, usually around 530°C, to fully dissolve the alloying elements into the aluminum matrix, forming a homogeneous solid solution.
• Stress Relief: To remove internal stresses generated during casting or processing, the 6082-T651 aluminum alloy undergoes a stress relief treatment. This process is achieved by stretching the metal by a certain amount, depending on the type of forged product being made (such as thin sheets, plates, rods, or forgings). Stress relief helps reduce warping and deformation that may occur during processing.
• Artificial Aging: After stress relief, the metal is heated to an appropriate temperature, usually between 160°C and 180°C, and held for a period of time to achieve the artificial aging condition. This process increases the strength and hardness of the aluminum alloy.
