The Al 2024 mechanical properties are critical for various applications. Here are some of the main mechanical properties of this alloy:
The tensile strength of 2024 aluminum alloy is usually between 350 MPa and 450 MPa, depending on the heat treatment state and the content of alloying elements. Its tensile strength can be further improved after proper heat treatment.
The yield strength of 2024 aluminum alloy is between about 280 MPa and 320 MPa. The yield strength is the point at which the material begins to deform plastically, which is critical for the design and use of structural parts.
The elastic modulus of 2024 aluminum alloy is usually between 70 GPa and 80 GPa, which means that it has a high ability to return to its original shape after being stressed. This is important for applications requiring stable shape.
2024 aluminum alloy can achieve higher hardness after proper heat treatment, usually between HB120 and HB150. This makes it ideal for applications where wear and scratch resistance is required.
7075 aluminum alloy is a kind of high-strength aluminum. Its main alloy elements include zinc, magnesium, copper and chromium. Through scientific and reasonable proportions, aluminium 7075 mechanical properties reaches a high level, like high strength, high hardness and good toughness.
7075-T651 is a 7075 aluminum alloy product that has been pre-stretch hardened after solution treatment and artificial aging treatment, which further improves the mechanical properties of the material, such as tensile strength, yield strength and fatigue strength.
In the aerospace field, 7075-T651 aluminum sheets are mainly used to make the main load-bearing structural parts of aircraft, such as fuselage frames, wing spars, landing gear components, propeller blades and various fasteners.
This aluminum alloy is light and high-strength, which can significantly reduce the weight of the aircraft, thereby improving fuel efficiency, reducing operating costs, and meeting the aircraft's performance requirements for high speeds, large loads, and extreme environments.
