We are surrounded by items that began their lives in a foundry – that is to say that they are cast metal items. Objects like lamp posts, train wheels, large-scale industrial equipment and even sculptures are cast out of metal.
Casting, according to https://en.wikipedia.org/wiki/Casting_(metalworking), is a process whereby solid metal items are created through placing liquid metal into moulds.
The steps involved include pattern making, moulding, melting and pouring, shakeout and cleaning.
Once metal shapes have been cast, they can then be turned into more complicated objects through the use of metal bonding adhesive like those found at http://www.ct1ltd.com/product-applications/metal-to-metal-adhesive/.
Let’s look at what metals are commonly used in the process.
This is a type of steel that has a chromium content that is higher than 10.5%. It is famous for being resistant to corrosion and also for its toughness. The more chromium and molybdenum the stainless steel contains, the more resistant it will be to corrosion. On a negative side, stainless steel is also known for having only middling tensile strength.
Aluminium is a popular casting metal thanks to its resistance to corrosion and its machinability, which results in a reduction of costs. It is used for a wide array of different applications.
Alloys that are copper-based have a very high resistance to corrosion, and due to this they are a very popular choice for cost-efficiency in the long term. Other properties depend on what other properties are added to the alloy. A popular choice is brass (copper and zinc) in addition to bronze (copper and tin and lead).
This is known for its great wear resistance. Many white irons contain high concentrations of chromium in addition to other alloys which can increase their performance in high temperatures and for increased resistance to corrosion.
Famous for their fantastic resistance to corrosion, nickel-based alloys normally consist of nickel coupled with iron, magnesium, zinc, copper and chromium. They are normally used because of their high tensile strength, ductility and resistance to wear. They are commonly used for chemical handling apparatus.
Due to the fact that carbon steel is made up of virtually no alloys, it provides a very high rate of machinability in addition to being easy to weld while maintaining its toughness.
