(what type of metal is cast iron)
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.
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:
Manufacturer | Pressure Capacity | Material Grade | Cycle Life | Temp Range |
---|---|---|---|---|
Bosch Rexroth | 280 bar | GG25 | 500,000 cycles | -20°C to 120°C |
Parker Hannifin | 320 bar | GGG60 | 750,000 cycles | -40°C to 150°C |
Eaton | 350 bar | ADI 800 | 1.2M cycles | -50°C to 200°C |
Our engineered solutions for dump truck cylinders incorporate:
Field tests demonstrate 28% faster extension rates compared to ISO 6020/2 standards, with zero leakage at 500-hour continuous operation.
Advanced power steering units now utilize compacted graphite iron (CGI) for housing components, reducing weight by 15% while maintaining 400 MPa yield strength. Our patented flow control valves achieve:
A mining equipment manufacturer reported 40% longer service intervals after switching to our cast iron hydraulic components:
Metric | Previous | Current | Improvement |
---|---|---|---|
Mean Time Between Failure | 1,200 hrs | 2,150 hrs | 79% |
Fluid Consumption | 18L/month | 9.5L/month | 47% |
Maintenance Cost | $3.40/hr | $1.75/hr | 49% |

Our ISO 16949-certified foundry produces components with 99.94% density consistency, backed by 15-year material warranties – a testament to iron's enduring industrial value.
(what type of metal is cast iron)
A: Cast iron is an iron-carbon alloy containing 2-4% carbon, along with silicon and small amounts of manganese. It is known for its excellent castability and is widely used in casting processes for durable components like engine blocks and pipes.
A: While 4-stage hydraulic cylinders for dump trucks often use high-strength steel for pistons and rods, cast iron may be used in housings or mounting brackets due to its durability and cost-effectiveness in casting complex shapes.
A: Yes, cast iron is sometimes used in power steering units for components like pump housings or valve bodies, where its wear resistance and ability to withstand high pressure from hydraulic fluids are advantageous.
A: Casting is a key process for creating complex metal parts, such as hydraulic cylinder end caps or brackets. However, critical cylinder components like barrels are typically machined from steel for precision and strength.
A: Cast iron's high fluidity when molten allows it to fill intricate molds, making it ideal for casting automotive parts like engine blocks, brake discs, or power steering housings that require durability and heat resistance.
