Distinguishing between different types of aluminum materials can be done in the following ways:
Composition: different types of aluminum materials have different alloy compositions. For example, the main component of pure aluminum is aluminum, while aluminum alloy will add other metal elements such as copper, magnesium, zinc and so on. The composition can be determined by chemical analysis.
Performance: The performance of different aluminum materials varies greatly. For example, hardness, some aluminum materials are softer, such as pure aluminum, while some aluminum alloys have higher hardness. There are also different properties such as strength, ductility, corrosion resistance, etc., which can be differentiated by testing these properties.
Appearance: From the appearance, different aluminum materials may have different color, surface finish and so on. However, this method is relatively inaccurate and can only be used as a preliminary judgment.
Use: Different types of aluminum materials usually have specific uses. For example, aluminum profiles for construction are usually specific aluminum alloys, while the aerospace field will use high-strength, lightweight aluminum alloys, which can be used to infer the type of aluminum material based on its use.
