7075 rolled aluminum forgings are one of the most commonly used materials in high-performance industrial applications. This type of aluminum forging boasts a unique set of mechanical properties and chemical composition that make it ideal for high-stress and high-load applications.
Chemical Composition of 7075 aluminum alloy
The chemical composition of 7075 rolled aluminum forgings consists of 5.6-6.1% zinc, 2.1-2.5% magnesium, 1.2-1.6% copper, and less than 0.5% of other elements. This composition gives 7075 aluminum forgings excellent corrosion resistance and high strength-to-weight ratio, making it ideal for use in marine, aerospace, and automotive applications.
Mechanical Properties
7075 rolled aluminum forgings have exceptional mechanical properties, including high tensile strength, good ductility, and exceptional fatigue resistance. They have a tensile strength of 83,000 psi and a yield strength of 73,000 psi, making them ideal for use in high-stress applications, such as aerospace components and military equipment.
Due to their high strength-to-weight ratio, 7075 aluminum forgings can be used in applications where space is limited, such as in bearings, gears, and other components that are subject to high loads and high stress. Because of their exceptional fatigue resistance, they can also be used in applications that require repeated load cycles, like aircraft landing gears.
