The storage requirements for aluminum castings are crucial for ensuring their quality and extending their service life. The following are the detailed requirements for the storage of aluminum castings:

First of all, the storage environment should be kept dry to avoid moisture and direct contact with water on the aluminum castings. The air humidity should be controlled within 50% to prevent the aluminum castings from oxidizing and corroding due to moisture. Meanwhile, the storage area should have good ventilation to ensure air circulation and reduce the accumulation of humidity.

Secondly, aluminum castings should be kept away from any substances that may have chemical reactions with them, such as acids, alkalis and other corrosive chemicals. These substances will react with aluminium, causing corrosion or discoloration on the surface of the castings, and even affecting their performance.

In addition, direct sunlight is also a factor that needs to be avoided when storing aluminum castings. Ultraviolet rays can accelerate the oxidation process of aluminium, causing an oxide layer to appear on the surface of castings, which affects their appearance and performance. Therefore, when storing aluminum castings, a cool place should be chosen or shading materials should be used to cover them.

To ensure the integrity of aluminum castings, they should also be placed in specific locations to avoid mutual squeezing or collision. Aluminum castings of different types and specifications should be classified and stored to facilitate management and search.

For aluminum castings that need to be stored for a long time, it is recommended to use appropriate packaging materials for protection, such as plastic bags and bubble wrap. These packaging materials can reduce the risk of air contact and physical damage, ensuring that the castings remain intact during storage.

In conclusion, the storage requirements for aluminum castings include maintaining dryness and ventilation, avoiding chemical reactions, preventing direct sunlight, classified storage, and appropriate packaging, etc. Adhering to these requirements can ensure that aluminum castings maintain their quality and performance during storage.
