T451 Temper 6082 Aluminum Treatment Process

Solution Heat Treatment: The aluminum alloy is first heated to a suitable temperature (around 530°C) to allow the alloying elements dissolved in the matrix to distribute evenly.
Stress Relief: The alloy is stretched by a certain amount to relieve internal stresses generated during the processing. The amount of stretching depends on the product type (thin sheet, plate, rod, or forging). This process helps reduce the internal stress of the material and improves the dimensional stability of the finished product.
Natural Aging: The alloy is allowed to naturally age at room temperature for a period of time, enhancing the material's strength and hardness.
