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, andcorrosive environments, but still need to pay attention to prevent corrosion. When using, avoid direct contact withother metals, avoid the use of corrosive cleaning agents and solvents, and avoid prolonged exposure to highhumidity.
Operating temperature: the high strength of 7175 aluminum alloy profile mainly comes from its solidsolution strengthening phase, which will fail at high temperature, so pay attention to avoid overheating and keepingit 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 processingprocesses such as extrusion, rolling, stretching, and die forging. Therefore, it is necessary to pay attention toselecting appropriate processing parameters and processes to avoid over-processing.
Instant QuoteSoftening: when performing local heating, care should be taken to avoid softening the 7175 aluminumalloy profile, so as not to affect its strength and toughness.
When purchasing 7175 aluminum profiles, you need to pay attention to the following points
Material standard: the performance and service life of 7175 aluminum alloy profiles are closelyrelated to their material quality. When purchasing, it is necessary to confirm that the material meets internationalor industry standards, such as American ASTM standards or aviation standards.
