2014 T6511 Aluminum
Similar to 2014-T651 aluminum, 2014-T6511 aluminum is first heated to a specific temperature through solution heat treatment, allowing the elements such as copper, manganese, and silicon in the alloy to dissolve evenly, improving the overall uniformity of the aluminum alloy.
2014-T6511 aluminum is the 2014 aluminum alloy in the T6511 temper, which undergoes a series of heat treatment processes to enhance its properties. Similar to 2014-T651 aluminum, 2014-T6511 aluminum is first heated to a specific temperature through solution heat treatment, allowing the elements such as copper, manganese, and silicon in the alloy to dissolve evenly, improving the overall uniformity of the aluminum alloy. Next, the aluminum alloy undergoes stress relief treatment to reduce the internal stresses generated during the processing, preventing deformation or cracking during subsequent use. Finally, artificial aging treatment is applied, causing the alloying elements dissolved in the aluminum matrix to precipitate, thereby significantly improving the strength and hardness of the alloy.
