CI casting

The defining feature of SG iron casting lies in itsgraphite structure. Unlike grey cast iron, where graphite appears in flake form and causes brittleness, SG iron contains graphite in aspherical shape. This nodular graphite structure significantly enhances the material’s strength, ductility, and impact resistance.

This transformation is achieved through a carefully controlled metallurgical process in which magnesium or similar nodulizing agents are introduced into molten iron. The result is a material that retains the excellent casting characteristics of iron while delivering mechanical performance comparable to many grades of steel.

The Importance of SG Iron Casting in Modern Manufacturing

Modern manufacturing environments demand materials that can withstand high loads, fluctuating temperatures, and continuous operational stress.SG iron casting

One of the major reasons industries prefer SG iron casting is itscombination of toughness and flexibility. The material does not fail suddenly under stress, which significantly reduces the risk of catastrophic component failure. This property is particularly valuable in automotive, infrastructure, and heavy machinery applications.
