Description of 7075 aluminum alloy
7075 aluminum is a high-strength alloy that belongs to the 7000 series of aerospace-grade materials. It is commonly used in the manufacture of structural components for aircraft, missiles, and spacecraft, as well as in other high-performance applications that require durability, toughness, and resistance to fatigue. The alloy is typically formed using a forging process that involves hammering or pressing a heated billet of material into the desired shape. The resulting 7075 aluminum forgings exhibit exceptional mechanical properties, including high strength, low density, and good corrosion resistance.
Chemical Composition:
The chemical composition of 7075 aluminum forging is characterized by high levels of zinc, magnesium, and copper, which are added to the alloy to improve its strength and fatigue resistance. The exact composition may vary depending on the specific manufacturer and application, but typical values are shown below:
Aluminum: 90.6-91.4%
Zinc: 5.1-6.1%
Magnesium: 2.1-2.9%
Copper: 1.2-2.0%
Other Elements: 0.5% max
Mechanical Properties:
The mechanical properties of 7075 aluminum forgings are exceptional, particularly in terms of strength, stiffness, and toughness. The material has a high yield strength and ultimate tensile strength, meaning that it can withstand heavy loads and resist deformation under stress. It also has a good fatigue strength, allowing it to resist cracking and failure over time. Other key mechanical properties include the following:
Density: 2.81 g/cm³
Melting Point: 477-635°C
Elastic Modulus: 71 GPa
Poisson's Ratio: 0.33
