When using aluminum coils in high-temperature environments, it's crucial to consider the material's melting point, which is around 660掳C (1220掳F). Ensure that the operating temperature does not exceed this threshold to avoid deformation or failure. Additionally, aluminum's strength and conductivity can be affected by high temperatures, so it's important to account for potential changes in performance. Protective coatings or treatments may be necessary to prevent oxidation and maintain the coil's integrity. Always consult material specifications and consult with material science experts to determine the suitability of aluminum coils for specific high-temperature applications.
