Understanding Cast Iron: Composition and Types

Cast iron is an iron-carbon alloy with a carbon content exceeding 2.11%, typically ranging between 2.5% and 4%. It contains **iron, carbon, silicon**, and trace amounts of **manganese, sulfur, and phosphorus**. The unique properties of cast iron stem from the form of carbon present in the alloy, which can be categorized into three main types:

• White Cast Iron: Carbon exists as cementite, resulting in a hard, brittle structure. Primarily used as a raw material for steelmaking.
• Gray Cast Iron: Carbon forms flake graphite, providing excellent machinability and vibration damping. Commonly used in engine blocks and machinery components.
• Nodular (Ductile) Cast Iron: Spherical graphite particles enhance strength and toughness, making it ideal for high-stress applications like valves and pump housings.

**Mingda's cast iron plates** are engineered to meet stringent industrial standards, ensuring durability and performance in demanding environments. The company's ability to produce **malleable cast iron** through high-temperature annealing further expands the material's versatility.
