Foundry casting is a case in which metal castings or shell cores are created. These castings or cores can be used for numerous things. Not all castings are the same, nor are they even created out of the same materials. In fact, the materials can be made up of a number of different types of metal. Read further below to learn about the many different types of metals that can be used in the process of creating castings.
More often than not, aluminum and cast iron are used for these processes. Aluminum is used for a variety of household items in addition to this process. It's a chemical element that is silvery white. The symbol of this element is AI. The atomic number of aluminum is 13. Aluminum is a popular choice for castings along with many other household items because it is probably the most abundant metal found on Earth. This makes it an inexpensive material to use.
Cast iron is the other more common metal that can be used for these processes. One of its most notable traits is that it is relatively brittle on its own. Malleable cast irons are the exception to this rule. This engineering material, like aluminum, can and has been used for many different types of applications. The facts that it has a low melting point, resistance to deformation as well as water resistance are just some of the reasons it is such a prime candidate for creating castings.
While aluminum and cast iron are the main types of metal that are sought after for casting purposes, they are not the only types that are used. In fact, there are several types that can be used. These types include steel, magnesium, zinc, tin and copper. Again, because these metals do not have the same appealing attributes as aluminum and cast iron, they are not used nearly as often in this sort of production.
Steel is most well known for its ductility, tensile strength and hardness. It's also relatively easy to weld. Another attractive factor about steel is the fact that it can resist rust quite well. Each of these attractive attributes for steel makes it a fine candidate for those who need a replacement for aluminum and cast iron. Magnesium is an element that is necessary for the human body to perform properly. In fact, of all the elements found in the human body, magnesium is the 11th most abundant. This goes to show its essential properties necessary to sustain life. Indeed, each of these metals listed here would be prime candidates for use in foundry casting.
