Ductile Iron Casting Part Series 6
JHshukong
Tailored for automotive safety-critical components, our High-Ductility Low-Defect Ductile Iron Casting Parts Series 6 combines exceptional elongation with meticulous defect control, meeting the rigorous demands of passenger vehicle and commercial truck applications. Cast from ASTM A536 Grade 65-45-12 and EN-GJS-400-18U, these parts feature a ferritic matrix for superior formability and impact resistance, ideal for suspension and powertrain components.
Ductility-Driven Design
High Elongation:
Elongation ≥18% (ASTM A536), 50% higher than standard ductile iron, enabling cold forming and reducing stress concentrations in suspension arms.
Low carbon equivalent (CE ≤4.3%), minimizing carbide formation and improving weldability for assembly with steel components.
Defect Control:
Porosity ≤0.3%, achieved through low-pressure sand casting and 100% X-ray inspection, surpassing IATF 16949 requirements for automotive critical parts.
Automotive-Grade Quality
Microstructure Purity: Spheroidization rate ≥99% (ISO 945: Grade 1), with graphite size ≥8 (ISO 945), enhancing fatigue life (10⁸ cycles at 150MPa) for wheel hubs and control arms.
Surface Finish: As-cast Ra ≤12.5μm, with optional shot peening (coverage ≥95%) to improve fatigue strength by 20% for stressed surfaces.
Process & Design Optimization
Thin-Wall Casting: Successfully produces 3-5mm walls for lightweight components (e.g., brake caliper brackets), reducing part weight by 15% compared to gray iron.
Mold Technology: 3D-printed sand molds enable complex undercuts and lightweight lattice structures, supporting advanced automotive designs (e.g., electric vehicle battery brackets).
Regulatory Compliance
Material Traceability: 100% traceable from melt to assembly, with each part serialized and linked to heat treatment records (ISO 22309 compliant).
Testing Rigor: 100% tensile, impact, and hardness testing per heat, with PPAP Level 3 capability for automotive OEMs.
Passenger Vehicles:
Suspension control arms, steering knuckles, and wheel hubs (IATF 16949 certified), providing 20% weight savings over steel while meeting FMVSS 124 impact standards.
Commercial Trucks:
Axle housings, differential cases, and brake components (SAE J2931 compliant), withstanding 500,000+ miles of cyclic loading without fatigue failure.
Electric Vehicles:
Battery brackets, motor mounts, and structural components, leveraging high ductility for crash resistance and lightweighting (ISO 26262 functional safety compliant).
Automotive Expertise
15+ years supplying Tier 1 OEMs, with experience in APQP, FMEA, and PPAP to ensure zero PPM defects in safety-critical parts.
Lightweighting Solutions
Design team specializes in substituting steel with ductile iron, achieving 30% weight reduction in suspension components without compromising strength (FEA validated).
Rapid Prototyping
5-day turnaround for 3D-printed sand molds and 10-day delivery for aluminum alloy prototypes, accelerating new model development by 40%.
Sustainable Manufacturing
100% recycled sand and 20% post-consumer recycled iron content, aligning with EU ELV Directive and OEM sustainability goals.
