The classification of aluminum materials is indeed diverse, and based on different classification criteria, we can obtain different classification results. The following is a detailed explanation of the classification of aluminum materials:

Firstly, according to production methods, aluminum can be divided into three categories: cast aluminum, rolled aluminum, and forged aluminum. Cast aluminum is commonly used for low strength components with low density requirements or products with high surface requirements, such as aluminum for construction and furniture. Rolled aluminum is widely used in transportation vehicles such as airplanes, cars, trains, as well as in fields such as construction, electronics, and furniture, due to its high strength, corrosion resistance, and good weldability. Forged aluminum is produced using forging machinery to press, draw, and other processes on aluminum, with a variety of application fields.

Secondly, according to its composition, aluminum can be divided into three categories: pure aluminum, aluminum alloys, and aluminum silicon alloys. Pure aluminum is the purest aluminum material, while aluminum alloy is an alloy material made by adding other metals, and aluminum silicon alloy is a type of aluminum alloy in which silicon element is added. Aluminum alloys can be further subdivided into Al Mn alloys, Al Cu alloys, Al Si alloys, and Al Mg alloys based on the type of metal added.

In addition, according to the pressure processing ability, aluminum can be divided into deformed aluminum and non deformed aluminum (such as cast aluminum). According to whether it can be heat treated for strengthening, aluminum alloys can be divided into non heat treated reinforced aluminum and heat treated reinforced aluminum. Alloys such as aluminum copper and aluminum magnesium silicon can enhance their strength through specific processes, known as heat treatable reinforced aluminum.

When selecting aluminum materials, we need to pay attention to the following points:

1. Check the factory qualification standards of aluminum materials, including the certificate of conformity, production date, size, construction technology, and production enterprise information.

2. Carefully inspect the appearance of the product. High quality aluminum should have a bright and glossy color, and there should be no obvious scratches or bubbles.

3. Ensure that the thickness of the product meets the regulations, especially for door and window products, the thickness should not be less than 1.2mm.

4. Pay attention to the thickness of the outer coating and the quality of the oxide film, both of which should not be lower than the standard value.

5. Choose suitable aluminum materials according to the usage environment. For example, in coastal areas, due to moisture and salt erosion, it is best to choose lightweight electrophoretic paint materials with superior corrosion resistance.

During daily cleaning and maintenance, hard objects such as brushes should be avoided to avoid damaging the surface of the aluminum material. Soft cotton cloth should be used for cleaning.

In summary, there are various classifications of aluminum materials, and when selecting aluminum materials, it is necessary to consider the actual needs and usage environment comprehensively. Meanwhile, proper maintenance and upkeep are also key to ensuring the long-term performance of aluminum materials.
