Understanding What Type of Metal Cast Iron Is

Cast iron constitutes an iron-carbon alloy containing 2-4% carbon content with 1-3% silicon, existing in four primary forms: gray, white, malleable, and ductile iron. This ferrous material demonstrates exceptional fluidity when molten, achieving 680-720 MPa compressive strength in standard grades. Its graphite microstructure enables superior vibration damping – 2.5x better than steel – making it ideal for 4 stage hydraulic cylinders requiring impact absorption.

Technical Advantages in Modern Manufacturing

Modern foundries employ advanced inoculation techniques to enhance tensile strength from 150 MPa (standard gray iron) to 900 MPa (austempered ductile iron). For hydraulic cylinders operating at 250-300 bar pressures, our proprietary alloy blend shows:

• 18% higher fatigue resistance than ASTM A48 Class 35
• 0.15mm/year corrosion rate in saline environments
• Thermal stability up to 450°C without deformation
