Materials to Choose From For Metal Casting
There are a lot of people that are now opting for items that have been designed in a definite way using mold. This is basically casting. You will learn that there are various metals that can be used in casting. Such materials have actually been used for a very long period of time. You will learn that these materials are mostly used in industrial applications. Some of the most common ones include the following.
We have the iron casting. This could either be gray iron or ductile iron. Gray iron is what is mostly used in industrial manufacturing. It is known to be both strong and versatile. This is what has led to the growth of its popularity within the market. It is quite easy to machine it as well as test its quality. You will realize that these can be done without employing any destructive method. More than often, they will be designed in such a way that meets specific specifications. It is quite appropriate for a number of applications. In most cases, such will include items that seek to have a high strength to weight ratios. They are known to be quite cost effective especially when produced in large volumes. Ductile iron casting is much appreciated when it comes to processes that require more strength. It is better when you need something that has a higher wear resistance. You will note that it is quite cost effective in comparison to gray iron casting.
We then have aluminum casting. It is much appreciated due to its strength and versatility. It is an adaptable substance that anyone will appreciate working with. It has a very high corrosion resistance as well as thermal conductivity. This metal is known to have better mechanical properties and strength even when exposed to high temperatures. It is for this reason that it is used for both die and permanent casting. You can also apply it on lost foam casting. Steel has almost similar traits. It is great for use on parts that are mre likely to suffer from both high wear and tear. In order to get better heat resistance properties, steel will mostly be mixed with either iron or nickel.
Copper is also a preferred material in metal casting. This is as a result of its improved electrical conductivity qualities. It is for this reason that most industries pick it for electrical components. It is defined by both great ductility and enhanced malleability. Its conduction of heat is unmatched. There are times that it will however have to be mixed with zinc so as to avoid formation of any internal cavities. You will also learn that indeed zinc is known to have a very low melting point.
