The compositions of gray and ductile iron castings are significant used materials in various industries. But what are they, and in what ways are they different? Let's find out!
Gray iron castings are of iron, mixed with carbon and silicon. They are called “gray” because they are usually gray when they shatter. It is stronger than gray iron castings but not as strong as steel and is more ductile than any steel. Ductile iron is also called “nodular” iron because of the form of the graphite inside the iron.
The advantages of gray iron castings are manifold. They’re also machinable, dampen vibration and conduct heat well. Due to their physical properties, gray iron castings are utilized in cars, and used as engine and brake blocks and most other car parts. They are used in the construction for pipes, valves and pump housings.
Ductile iron castings are also more flexible than gray iron castings and not as brittle, because they have an elastic nodular graphite structure. That makes them great for things that need to last a long time, such as gears, crankshafts and axles. Farm equipment such as plows are also made of ductile iron castings.
There are advantages to each of these types of iron castings, both gray iron castings and ductile iron castings. Gray iron castings are strong and endure wear; ductile iron castings are stronger and can stretch further before breaking. That is, gray iron is better for items that don’t require as much strength, while ductile iron is good for items that need to spring back instead of shatter.
To determine the best option between gray and ductile iron castings for your needs, you should consider what you need. 3. Gray iron castings If you desire a structure heats easily and relieves very good, gray castings might be ideal for you. Ductile Iron Castings If you want something that’s going to be strong, nailable, and impact resistant, ductile iron castings is probably going to be better. That’s why you should choose a reliable source who will provide you with the best quality iron casting for your purpose.
