Usage limitations of AA7075.
| Type of limitation | References |
|---|---|
| Difficulty in joining by conventional fusion-welding techniques | [37] |
| Involves complicated process for welding and it is highly reactive to caustic acids, water, and oxygen. | [31] |
| Poor tribological properties | [4,14,20,25,38–42] |
| Fatigue cracks due to cyclic loading is one of the most important issues in these alloys | [43–45] |
| Poor mechanical and the tribological properties at high temperatures | [18] |
| Reduced strength and hardness due to residual coarse and insoluble secondary phases | [19] |
| Lower compression strength and hardness | [46] |
| Formation of built-up-edge to lower machinability and reduce tool life | [23] |
