What is the main working principle of aluminum profiles?

Aluminum profiles are formed by extruding aluminum alloy bars into T- and U-shaped cross-sections through a die. Their primary working principle is to control shape and size through plastic deformation of the metal. Specifically, the raw material is first heated to a certain temperature and then heat-treated to achieve a certain strength. A dedicated extruder is then used to cut the aluminum bar into small sections of the desired specifications and feed them into a die. The plastic deformation under high pressure and high temperature causes the aluminum profile to undergo significant elastic deformation before cooling and setting the shape. This process, due to the material's plasticity and excellent heat dissipation properties, gives aluminum profiles excellent mechanical properties and a wide range of applications.
