It can contain at least one element selected from the group consisting of f. These elements strengthen the alloy strength by making the crystal grains finer, and at the same time form compounds with Al to improve the heat resistance of the alloy. However, the content of each of these elements must be 4% by weight or less, and if the content exceeds 4% by weight, the alloy will become brittle.
