Introduction
Cast Iron with Graphite is a type of alloy that has been used in applications from steam engines to stove grating for centuries. Its toughness, resistance to corrosion, and excellent machinability make it one of the most popular materials for industrial use. In addition, the inclusion of graphite promotes lubricity and strength, which makes cast iron with graphite even more beneficial in certain settings.
Uses of Cast Iron
Cast iron is by far the most popular material used in the making of parts such as machine frames, gears, springs, gaskets, and many other components of machines. Cast iron has properties such as being strong, ductile, and resistant to corrosion which make it suitable for producing parts that require minimal maintenance over time. This is why it has become a staple in the industrial world where parts are expected to last for decades with regular upkeep.
Graphite and Its Role in Cast Iron
Graphite has been used in cast iron for over a century and is most commonly found in its form as flakes. Adding flakes of graphite to iron during the casting process causes its brittle nature to transform into a harder and more ductile material as the flakes form a matrix of graphite crystals in the microstructure of the cast iron. These crystals work to provide structural strength to the iron and thus add to its resistance to wear and tear. In addition, the lubrication provided by the graphite reduces friction between different parts and increases the mechanical efficiency of the iron.
Conclusion
Cast iron with graphite is one of the most popular materials used in the making of industrial parts and components. The inclusion of graphite in the alloy allows it to be stronger and more resistant to corrosion than pure cast iron. In addition, the graphite acts as a lubricant which reduces friction and improves the mechanical efficiency of the metal. As such, it is clear why cast iron with graphite is so ubiquitous throughout the industrial world and why it will remain a popular choice for many years to come.
