Iron is one of the most fundamental metals on Earth. It can be found in various other common alloys, including stainless steel, carbon steel, and numerous other superalloys and metal alloy groups. But what about cast iron? There are many questions surrounding the iron recycling industry, like “Is cast iron even iron at all?”
Continue reading to learn more facts about cast-iron, including its common components, common applications, and whether or not it can be recycled.
Basic Facts About Cast Iron Metal
Many people mistakenly assume that cast-iron materials are made of 100% iron. But the truth is, cast iron is any metal alloy of which the primary element is iron. This makes up a large family of metal alloys. Here is an interesting fact to help you better understand the use of cast-iron: many carbon steels have more iron elements in them than cast-iron metals.
So, what makes an alloy cast iron? Well, the universally-agreed upon definition is any metal alloy that is predominantly iron and contains less than 2% of carbon. Cast iron frequently contains other alloying elements, such as manganese and silicone.
Types of Cast Iron
There are many types of cast-iron alloys, but the four primary categories include white cast-iron, gray cast-iron, ductile cast iron, and malleable cast-iron.
White cast iron contains high quantities of iron carbides, rendering it more brittle, but giving it enhanced water resistant capabilities. Gray cast iron contains graphite flakes, thus enhancing its machinability properties.
Ductile cast iron is composed of graphite nodules, giving it more ductility than other versions of cast-iron. It retains high tensile strength. Malleable cast iron is white cast iron that has been heated treated so to alter iron carbides into graphite nodules. This makes it similar to ductile cast iron.
Common Applications of Cast Iron
There are many commodities in the world that are made from cast-iron and similar alloying metals, including automotive parts like engine blocks, disc brakes, chains, sprockets, gears, gear plates, rods and shafts, and more. It is also used to manufacture machinery, housing, cookware, and even mining equipment.
