Cast iron is a class of iron–carbon alloys with a carbon content of more than 2% and silicon content around 1–3%. Its usefulness derives from its relatively low melting temperature.
Apr 1, 2024 · The types of cast iron are primarily classified based on the form of carbon and the morphology of graphite present. The following are the main types of cast iron: White Cast Iron: Carbon exists in the form of cementite (Fe3C), and the fracture surface is silvery white. It’s brittle and is rarely used alone.

Aug 3, 2023 · Various types of cast irons are produced using different heat treatment and processing techniques, including gray iron, white iron, malleable iron, ductile iron, and compacted graphite iron. Cast iron design details are produced by smelting metal and pouring it into a mold.
Types of Cast Irons. There are four basic types of cast irons: white iron, gray iron, ductile iron, and malleable iron. White iron contains a large percentage of eutectic carbides which increase hardness at the expense of toughness.
Cast iron can be classified into grey cast iron, white cast iron, malleable cast iron and ductile cast iron, depending on its composition. Grey cast iron, or gray iron, has a dark grey fracture colour due to a graphitic microstructure.
What Are The Types Of Cast Iron? There are four basic types of cast iron – white iron, gray iron, ductile iron, and malleable iron: 1. White iron. 2. Gray iron. 3. Ductile iron. 4. Malleable iron.
The 4 types of Cast iron are presented below along with its composition, Microstructure, properties, Fracture surface and applications. Gray cast iron. White cast iron. Malleable cast iron. Nodular or SG or ductile iron. Grey Cast Iron: These types of cast iron are widely used. Presence of graphite in the form of flakes (like fibre) Composition:
Here are some of the most common types of cast iron: Gray iron: Gray iron is the most common type of cast iron, accounting for around 80% of all castings.
This article discusses criteria that can be used for the classification of cast iron: fracture aspect, graphite shape, microstructure of the matr.
