The 798 aluminum profile produced through extrusion is used extensively in construction, automotive, and aerospace industries.
Heat treatment processes are crucial for developing the desired mechanical properties in the 798 series aluminum. Solution heat treatment involves heating the alloy to a high temperature to dissolve soluble phases, followed by rapid cooling to retain a supersaturated solid solution. Aging, either at room temperature (natural aging) or elevated temperatures (artificial aging), allows for precipitation hardening, increasing the alloy's strength and hardness.
The careful control of heat treatment parameters is essential to achieve optimal properties. Factors such as time, temperature, and cooling rate must be precisely managed. These processes enable manufacturers to customize the alloy's properties for specific applications, enhancing performance and extending the service life of the components.
