Types and Applications of Commonly Used Iron Castings
Cast iron is a common metal material with good mechanical properties and corrosion resistance. Iron castings are widely used in various industries, such as automobiles, machinery, construction, electricity, agriculture, and so on. This article will introduce the types and applications of cast iron castings.
1. Grey cast iron is a type of cast iron with a high carbon content, usually containing 2.5% -4% carbon. It has high strength and hardness, but poor toughness. Grey cast iron is commonly used in the manufacturing of large castings such as machine tools, automotive engine blocks, fan impellers, valves, pipelines, etc.
2. Ductile iron is a type of cast iron with a low carbon content, typically containing 2.2% -3.6% carbon. It has good strength and toughness, as well as good wear resistance and impact performance. Ductile iron is commonly used for manufacturing wheels, mechanical parts, water pump housings, pipelines, bearing seats, etc.
3. White cast iron is a type of cast iron with a high carbon content, usually containing 3.2% -4.5% carbon. It has high strength and hardness, but poor toughness. White cast iron is commonly used in the manufacturing of cutting tools, hammer heads, hammer handles, milling cutters, etc.
4. Alloy cast iron is a type of cast iron containing alloying elements such as chromium, nickel, and molybdenum, which has high wear resistance, corrosion resistance, and high-temperature performance. Alloy cast iron is commonly used for manufacturing refractory materials, high-temperature pipelines, aviation engine components, etc.
In short, cast iron is an important metal material widely used in various industries. Different types of cast iron have different mechanical properties and corrosion resistance, and suitable cast iron materials can be selected according to different usage conditions. With the continuous development of casting technology, the quality and performance of cast iron castings are also constantly improving, providing better material choices for various industries.
