Ductile iron, a powerful material


Many people are not familiar with the term vermicular cast iron, but it is an indispensable and important material in modern industrial production. Vermicular cast iron is known for its excellent strength, toughness, and wear resistance, and is an indispensable material for important parts in aerospace, automotive, military and other fields.

Many people are not familiar with the term compacted graphite iron, but it is an indispensable and important material in modern industrial production. Compacted graphite iron is known for its excellent strength, toughness, and wear resistance, and is an indispensable material for important components in aerospace, automotive, and military industries.

 Compacted graphite iron

The name of compacted graphite iron comes from its microstructure, which is similar to that of worms. Compared with other cast iron materials, it has better deformability, fracture toughness, and fatigue resistance, and can withstand greater loads and use in harsher environments. In addition, it also has good corrosion resistance and thermal stability, and can operate stably for a long time in high temperature and high pressure environments. Therefore, it is also one of the most suitable materials for high temperature and high pressure equipment such as boilers, pressure vessels, and fan impellers. It also appears frequently in our daily lives. Cast grills, hooks, cutting boards and other household appliances are made of it. With people's pursuit of healthy diet, cast iron pots are becoming more and more popular. The material has the advantages of non-stickiness and easy cleaning, and is a very good cookware material.


No matter which field it is in, compacted graphite iron has its unique advantages and value. This magical material has become an indispensable and important material in the modern industrial world with its good performance and wide range of applications. When I was a child, my favorite food was sweet and sour fish made by my father, which was simply unforgettable. Later, as I grew older, the pots and pans at home became more and more luxurious, but I always felt that something was missing when I wanted to make the sweet and sour fish I had when I was a child. Until one day, I saw a cast iron pot in a kitchenware store. This pot is made of compacted graphite iron.


With anticipation and doubt, I bought this pot and prepared to cook my sweet and sour fish. After the pot was heated, the heat was quickly and evenly transferred, and only a small amount of oil was needed to fry, stir-fry, boil and roast the ingredients. The ingredients for the sweet and sour fish were added step by step, and the compacted graphite iron pot retained the original flavor of the ingredients very well, and the familiar aroma of sweet and sour sauce was emitted. When I tasted it, not only was the taste of the sweet and sour sauce restored, but the freshness and bite of the fish were also better than before. At this time, I suddenly realized that the reason was that the pot I used before was not good, which caused the cooked food to fail to fully present its original flavor.


The emergence of compacted graphite iron material has allowed me to regain the deliciousness of my childhood, and it has also made me understand an art in the kitchen. Whether it is making delicious food or enjoying delicious food, compacted graphite iron pot is a very good choice, because it is not only beautiful and practical, but also pays attention to the original taste of the ingredients, and has become a companion on the table of food lovers.
