castgti

Castgti is a term that refers to a specific type of cast iron alloy. It is a nodular graphite cast iron, also known as ductile iron or spheroidal graphite iron. The key characteristic of castgti is the form of graphite present in its microstructure. Instead of appearing as flakes, the graphite is in the form of spheres or nodules. This spherical morphology significantly enhances the mechanical properties of the material compared to gray cast iron, where graphite is present as flakes.

The production of castgti involves the addition of magnesium or cerium to molten iron during the casting process. These elements promote the formation of spherical graphite. As a result, castgti exhibits higher tensile strength, ductility, and toughness. It also possesses good wear resistance and fatigue strength, making it suitable for a wide range of engineering applications.

Common uses for castgti include automotive components such as crankshafts and steering components, agricultural machinery parts, pipes and fittings, and heavy equipment. Its ability to be forged or machined after casting further increases its versatility. The specific properties of castgti can be further tailored through heat treatment processes.
