Aluminum is a lightweight and high-strength metal that is often used in the manufacture of aircraft, automobiles, electronic equipment and other products. Of course, as a material, aluminum also needs to understand its basic physical properties. Among them, the elastic modulus is an important indicator. In this article, we will introduce the elastic modulus of aluminum in detail. What is the relationship between the elastic modulus of aluminum and aluminum alloy die castings?

The elastic modulus, also known as Young’s modulus, is a physical quantity that measures the ability of a solid material to resist deformation and compression. It describes the relationship between strain and stress, that is, the size of the corresponding strain generated by the material under a given stress. The larger the elastic modulus, the stronger the material’s ability to resist external strain or compression.

For aluminum, the elastic modulus is about 68-79 GPa. The specific value in this range depends on the composition, purity and processing of the aluminum. In addition, temperature and stress level will also affect the elastic modulus of aluminum.

The elastic modulus of aluminum can be measured in a variety of ways. The most common method is to use the cantilever beam method. This method is to fix an aluminum rod of known length at one end and hang the other end in the air, and then add a known force, and then measure the degree of bending of the aluminum rod when it is subjected to this force. Based on the geometric dimensions and physical parameters of the aluminum rod, the elastic modulus of aluminum can be calculated. In addition, there are other methods that can be used to measure the elastic modulus of aluminum, such as compression test method, tensile test method, etc.

The elastic modulus of aluminum is an important physical indicator that reflects the mechanical properties and structural stability of aluminum materials. In practical applications, people must consider optimizing the elastic modulus of aluminum materials to ensure that they can still work normally under different temperatures and stress levels. Therefore, it is very important for people who master the use and design specifications of aluminum materials to understand the elastic modulus of aluminum.
