Custom Door and window building profiles

How are the temperature and time of aging treatment determined to improve the mechanical properties of door and window building profiles?

Aging treatment, also known as artificial aging or stabilization treatment, is a process in which aluminum alloy materials are heated to a certain temperature and maintained for a certain period of time, followed by natural cooling or forced cooling. This process aims to eliminate or reduce the residual stress generated during the processing of the material, while promoting the stabilization of the internal structure of the alloy, thereby improving the hardness, strength, corrosion resistance and dimensional stability of the material. For door and window building profiles, good aging treatment can significantly improve its wind pressure resistance, air tightness and water tightness, extend its service life, and meet the high standards of energy conservation, environmental protection and aesthetics of modern buildings.
Aluminum alloys with different alloy compositions respond differently to aging treatment. For example, the optimal temperature and time during aging treatment of commonly used construction aluminum alloys such as 6061 and 6063 will be different. The content of copper, magnesium, silicon and other elements in the alloy will directly affect the aging effect. Therefore, we first initially set the temperature range for aging treatment based on the specific composition of the alloy, combined with past experimental data and industry experience.
The microstructural structure of aluminum alloys, such as grain size, phase distribution and morphology, will also affect the effect of aging treatment. Through advanced testing equipment such as metallographic microscopes, we can observe the microstructure inside the material and adjust the aging treatment parameters accordingly to achieve the best microstructure optimization effect.
Based on customer needs and international standards, such as air tightness, strength, leakage prevention and other specific performance indicators, we will further fine-tune the temperature and time of the aging treatment. For example, for door and window profiles that require extremely high wind pressure resistance, a higher aging temperature and a slightly longer aging time may be required to obtain a more stable structure and higher strength.
Based on the above analysis, we will conduct a series of experiments to draw performance change curves (age hardening curves) under different temperature and time combinations to find the best balance point for performance improvement. During this process, we will use testing equipment such as Vickers hardness testers to conduct hardness tests on samples that have undergone different aging treatments, combined with other mechanical property tests, such as tensile tests, to determine the optimal aging treatment parameters.
In our production practice, the temperature of aging treatment is usually controlled between 150°C and 200°C, and the time ranges from several hours. The specific value is determined based on the above principles. In order to ensure the performance consistency of each batch of products, we adopt an advanced temperature control system that can accurately control the temperature fluctuation in the furnace within ±5°C. At the same time, we use the timer on the automated production line to accurately record the aging time to avoid Human error.
In addition, we continue to develop and optimize the cooling process after aging treatment, using rapid air cooling or water cooling technology to effectively control the cooling rate of the material, further promote the release of internal stress and the stability of the organizational structure, thereby improving the overall performance of the product.
