Description
- Mechanical Property Changes: The yield strength and tensile strength of aluminum alloys gradually decrease with increasing temperature1. For instance, the strength of 6061-T6 aluminum alloy will decline at high temperatures, thus weakening the load-bearing capacity of the material.
- Thermal Expansion Issues: Aluminum has a relatively large coefficient of thermal expansion, which can lead to dimensional changes and thermal expansion and contraction problems1. In high-temperature areas, aluminum roofing and wall systems need to consider 预留伸缩缝等 to adapt to thermal expansion.
- Corrosion Resistance Changes: High temperatures can accelerate the oxidation reaction rate and diffusion process, increasing the corrosion rate of aluminum materials1. In high-temperature alkaline environments, the corrosion resistance of aluminum-magnesium-manganese alloy plates may decrease.
- Antioxidant Performance Changes: Although the surface of aluminum metal materials can form a dense oxide film, high temperatures may affect the stability of the oxide film, causing local rupture or peeling.
- Mechanical Property Changes: Some aluminum alloys show an increase in tensile strength and a decrease in fracture toughness as the temperature drops1. For example, 7075-T6 aluminum alloy has good low-temperature strength and is suitable for use in low-temperature regions.
- Appearance Changes: In extremely cold conditions, the color of aluminum materials may darken or fade. The pigments in the coating become less active, affecting the appearance of aluminum curtain walls and other decorative materials.
- Corrosion Issues: Humid air can significantly reduce the fatigue performance of aluminum alloys, increasing the corrosion rate1. In coastal areas with high humidity and salt content in the air, aluminum roofing and walls are more prone to corrosion.
- Appearance Changes: Long-term exposure to humid environments can damage and peel off the coating on the surface of aluminum materials, affecting their aesthetics and decorative effects.
- Appearance Stability: Dry climate has little effect on the appearance of aluminum metal materials, and their performance and appearance generally remain stable1. Industrial pure aluminum or ordinary aluminum alloys can maintain good performance in dry inland areas.
- Other Potential Influences: In extremely dry environments with sand and other particulate matter, aluminum materials may suffer surface wear, affecting the surface finish and the integrity of the protective film, and thus affecting their corrosion resistance and service life to some extent
