CAST IRON COMPARISON TABLE
Cast iron is an alloy of iron and carbon that is used in a variety of applications and industries. Cast iron is valued for its excellent strength and machinability properties, as well as its high corrosion resistance. It is one of the oldest and most durable alloys. Due to its malleability, cast iron can be formed into intricate shapes and components. This makes it ideal for automotive, construction, and manufacturing applications. Additionally, it is highly resistant to wear, making it a popular material in many industries.
In this section, we will take a look at the various types of cast iron. We will also compare their functions and properties so that you can better understand how to select the appropriate alloy for your specific application. Read on to learn more!
Gray Cast Iron: This is one of the most commonly used cast irons and is characterised by its grayish colour tint. It is most commonly used in automotive and engineering applications due to its high shock absorbency and excellent wear resistance. It also has a relatively low melting point, making it suitable for die casting applications.
White Cast Iron: This is a hard, brittle cast iron that is characterised by its white colour. It is primarily used in the manufacture of large construction components. It has a higher melting point than gray cast iron, making it more suitable for heat treatment processes. Additionally, it is highly resistant to corrosion and abrasion.
Malleable Cast Iron: This is the most malleable of all cast irons and is used in a variety of manufacturing applications. Due to its malleability, it can be easily machined into a wide range of shapes and sizes. Additionally, it is highly resistant to wear, making it ideal for use in industrial and agricultural machinery.
Ductile Cast Iron: This is a relatively new type of cast iron that has become increasingly popular in recent years. It is characterised by its dark grey colour and is renowned for its excellentstrength to weight ratio. It is also highly resistant to corrosion and wear, making it a suitable choice for use in harsh environments.
Compacted Graphite Iron: This is a relatively new and popular type of cast iron. It is notable for its high strength and low-weight properties. Additionally, it is highly resistant to corrosion and wear, making it suited for use in a variety of automotive, marine, and off-road applications.
Pearlite Cast Iron: This is a special type of cast iron that is made from a unique heat treatment process. It is characterised by its grey colour and is renowned for its excellent strength and machinability properties. Additionally, it is highly resistant to corrosion and wear, making it suitable for use in a variety of harsh environments.
Overall, cast iron is an incredibly versatile and durable material that has a variety of applications. Before selecting an alloy, it is important to consider the specific characteristics of the various types of cast iron available. Only then can you make an educated decision and select the alloy that best meets your needs.
