Gray Iron Castings
What is Grey Cast Iron?
Grey cast iron (EN-GJL) is the most commonly used cast iron, featuring flake graphite structure that enables excellent thermal conductivity, vibration damping, and machinability. It is widely used in automotive, heating, construction, and machine manufacturing industries. Thanks to its structure, it allows economical and high-volume production with stable quality and predictable behavior.
Advantages of Grey Cast Iron
Key benefits that make grey cast iron the preferred choice for many applications
- High thermal conductivity
- Excellent damping capacity
- Easy and cost-efficient machining
- Ideal for high-volume production
- Affordable material and tooling cost
Microstructure
The lamellar graphite structure allows fast heat dissipation and energy absorption. Microstructure is optimized through controlled cooling, alloying, and molding methods. Regular metallographic inspection ensures consistency, prevents internal defects, and maintains dimensional integrity.
