application of 7175 aerospace aluminum profilee

7175 aluminum profiles need to pay attention to the following matters when using

Anti-corrosion: 7175 aluminum alloy profiles can be used in high-temperature, high-humidity, and corrosive environments, but still need to pay attention to prevent corrosion. When using, avoid direct contact with other metals, avoid the use of corrosive cleaning agents and solvents, and avoid prolonged exposure to high humidity.

Operating temperature: the high strength of 7175 aluminum alloy profile mainly comes from its solid solution strengthening phase, which will fail at high temperature, so pay attention to avoid overheating and keeping it in a high temperature environment for a long time when using it at high temperature.

Processing: 7175 aluminum alloy profiles are prone to deformation and cracks in processing processes such as extrusion, rolling, stretching, and die forging. Therefore, it is necessary to pay attention to selecting appropriate processing parameters and processes to avoid over-processing.Quick Quote

Softening: when performing local heating, care should be taken to avoid softening the 7175 aluminum alloy profile, so as not to affect its strength and toughness.
