Premium Material: GGG50 Ductile Iron
GGG50 (Grade 500-7 per ISO 1083) represents an optimal balance of strength and ductility in cast iron materials, characterized by:
Minimum tensile strength of 500 MPa and yield strength of 320 MPa
Elongation of 7% minimum, providing excellent impact resistance
Brinell hardness of 170-230 HB, ensuring superior wear resistance
Enhanced fatigue strength and exceptional pressure tightness
Superior vibration damping capacity compared to steel alternatives
The spheroidal graphite microstructure, achieved through controlled magnesium treatment, delivers these exceptional properties while maintaining excellent casting fluidity and machinability. This unique combination allows for the production of complex geometries with consistent material properties throughout the casting.
