Cast Iron Sheet Metal Fabrication
Rapidaccu delivers specialized cast iron sheet metal fabrication with 15 years of manufacturing expertise. We produce durable, wear-resistant cast iron components for automotive, machinery, and heavy industrial applications requiring exceptional damping properties and thermal stability.
Cast Iron Performance Advantages
Unique properties make cast iron ideal for demanding industrial applications
Exceptional Wear Resistance
Graphite flakes provide self-lubricating properties reducing friction and wear. Superior abrasion resistance extends component life in harsh environments.
Vibration Damping
Outstanding damping capacity absorbs vibrations and reduces noise. Ideal for machine bases, engine blocks, and precision equipment foundations.
Thermal Stability
Excellent thermal conductivity and low thermal expansion. Maintains dimensional stability across temperature fluctuations and thermal cycling.
High Compressive Strength
Superior compressive strength compared to tensile strength. Excellent for applications involving heavy loads and bearing pressures.
Cost-Effective
Lower material costs than steel alloys with excellent castability. Complex shapes can be produced economically through casting processes.
Excellent Machinability
Gray cast iron machines easily producing good surface finishes. Graphite flakes act as chip breakers reducing tool wear during machining.
Cast Iron Types & Specifications
Different cast iron grades optimized for specific performance requirements
Gray Cast Iron
Carbon Content: 2.5-4.0%
Microstructure: Graphite flakes in ferrite/pearlite matrix
Most widely used cast iron with excellent machinability, wear resistance, and vibration damping. Graphite flakes provide lubricity and chip breaking during machining.
Typical Applications:
- Engine blocks and cylinder heads
- Machine tool bases and frames
- Brake rotors and drums
- Pump housings and manifolds
Ductile Iron
Carbon Content: 3.0-4.0%
Microstructure: Spheroidal graphite nodules
Also known as nodular iron, offers higher strength, toughness, and ductility than gray iron. Spheroidal graphite provides improved mechanical properties while maintaining castability.
Typical Applications:
- Crankshafts and gears
- Suspension components
- Heavy-duty valve bodies
- Wind turbine components
White Cast Iron
Carbon Content: 2.5-3.5%
Microstructure: Carbide structure, no graphite
Extremely hard and wear-resistant but brittle. Carbon exists as iron carbide rather than graphite. Excellent for applications requiring maximum abrasion resistance.
Typical Applications:
- Crushing equipment liners
- Grinding mill components
- Wear plates and surfaces
- Mining equipment parts
Malleable Iron
Process: Heat-treated white iron
Microstructure: Temper carbon nodules
White cast iron heat-treated to convert carbides into graphite nodules. Offers good ductility and impact resistance with moderate strength and excellent machinability.
Typical Applications:
- Pipe fittings and flanges
- Agricultural equipment
- Hand tools and wrenches
- Railroad equipment
