Chemical composition of cooking bag foil
|Si + Fe
|The chemical composition will affect the performance and can be produced according to the standard required by the customer.
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.
