Aluminum sand casting is a metal casting process where sand is used to mold material together.

Currently, a majority of metal castings are produced by the sand casting process. This is largely because aluminum sand casting is a very cheap and effective means of molding material together.

Sometimes for increased durability, the sand will be mixed with clay. This mixture will moisten when added with water, and then strengthen when it dries afterward. This makes it much more suitable for molding.

However, clay does not always need to be used for this method. Sometimes one method that is used for aluminum sand casting method is the air set method. When the air set method is utilized, an adhesive material other than clay is most often used.
