Can aluminum sheets be used in high-temperature environments?

Yes, aluminum sheets can be used in high-temperature environments, but with certain considerations. Aluminum has a high melting point of around 660掳C (1220掳F), which allows it to withstand high temperatures. However, its mechanical properties can degrade over time when exposed to sustained high temperatures, especially above 200掳C (392掳F). For applications requiring long-term exposure to high temperatures, special heat-resistant aluminum alloys or coatings may be necessary to maintain structural integrity and performance. It's also important to consider the specific conditions and the maximum temperature the aluminum will be exposed to when determining its suitability for a high-temperature application.
