Effect of chemical composition on the performance of cooking bag foil
Effect of chemical composition on 1235 cooking bag foil
- The solid solution of Fe and Si in Al will increase the material's work hardening rate, leading to a relatively higher rolling difficulty for Cooking Bag Foil.
- The mechanical properties of 1235 aluminum foil for Cooking Bag Foil are not only affected by purity and Fe/Si content but also by the Fe/Si ratio.
Effect of chemical composition on 8011 8079 cooking bag foil
- Adding an appropriate amount of Cu to the alloy can enhance its strengthening ability during annealing.
- The alloy with a higher manganese content has a higher yield strength compared to an alloy with a lower manganese content under the same conditions.
- Chromium (Cr) can also impede the nucleation and growth processes of recrystallization, impart a certain degree of strengthening to the alloy, and improve its toughness.
