The material of an aluminium window profile is primarily aluminium. This metal provides a strong, lightweight, and durable framework for the window. Aluminium window profiles are often extruded, meaning they are formed by pushing aluminium through a die to create a long, seamless profile that can be cut to size.
Aluminum window profiles are made of aluminum alloys such as 6063, 6060, 6061, 6005, and 6082 12. These alloys are known for their corrosion resistance and strength-to-weight ratio. The aluminum billet used to make these profiles is typically of national standard .
To enhance the performance characteristics of the window profile, aluminium may be alloyed with other elements, such as copper or zinc, to increase its strength. Additionally, the surface of the aluminium can be coated with paint, anodized, or finished with a powder coating to improve its appearance, resistance to wear, and protection against the elements.
In some cases, other materials may be used in conjunction with the aluminium, such as polyamide or thermal breaks to improve insulation and reduce heat transfer. These materials are often integrated into the design of the window profile to create a more energy-efficient product.
