1. Narrow forging deformation temperature range. For most aluminum alloys, the forging deformation temperature is within 350–450°C, with a working range of approximately 100°C.

2. Sensitive to strain rate. Forging equipment with lower operating speeds and stable velocity should be selected.

3. Strict requirements for heating and forging temperatures. Due to the narrow deformation temperature range of aluminum alloys, the upper limit of the allowable temperature should be used whenever possible to extend forging operation time. This requires high-precision furnaces and temperature control instruments; otherwise, overheating may easily occur.

4. High friction coefficient between aluminum alloys and steel dies, combined with poor flowability during deformation, makes it difficult for the metal to fill die cavities. Additional steps and dies are typically required, along with larger fillet radii on tooling.

5. High adhesion tendency. During severe large-deformation forging, the billet tends to stick to the die, which can easily cause surface peeling, warping, and other defects, as well as accelerate die wear. In severe cases, both the forging and the die may be scrapped.

6. High sensitivity to cracking. Cracks generated during the forging process, if not promptly removed, will rapidly expand in subsequent forging operations, leading to scrappage of the forging.
