Which Aluminum Profile T4, T5, T6 Is Better For Door & Window?

When it comes to choosing the right aluminum profile for doors and windows, the decision often boils down to the temper grades: T4, T5, and T6. Each of these tempers offers unique properties that cater to different needs, but which one is the best fit for your project? Let’s break it down.

T4 Aluminum Profile:
T4 is a naturally aged aluminum profile that offers good formability and moderate strength. It’s often used in applications where the material needs to be bent or shaped after extrusion. However, it may not be the best choice for high-stress environments, as it lacks the hardness of T5 and T6.

T5 Aluminum Profile:
T5 is artificially aged after extrusion, providing a balance between strength and formability. It’s a popular choice for door and window frames because it offers better mechanical properties than T4 while still being relatively easy to work with. T5 profiles are known for their durability and resistance to deformation, making them ideal for residential and commercial applications.

T6 Aluminum Profile:
T6 is the strongest of the three, offering superior hardness and tensile strength. It’s artificially aged and then solution heat-treated, making it perfect for high-stress applications. However, this increased strength comes at the cost of reduced formability, so it’s less suitable for projects that require extensive bending or shaping.
