Gray Iron Casting Series 2
JHshukong
Engineered for industrial machinery operating in high-temperature and vibratory environments, our Vibration-Damping High-Temp Gray Iron Casting Series 2 leverages gray iron’s inherent damping capacity and thermal stability. Cast from ASTM A48 Grade 60 and EN-GJL-300, these parts reduce noise and vibration while withstanding temperatures up to 400°C, ideal for engine components, pumps, and industrial gearboxes.
Thermal & Vibration Performance
Damping Capacity: Loss factor ≥0.02 (ASTM E797), 3x higher than steel, effectively reducing noise and vibration in machinery (e.g., diesel engines, compressors).
High-Temp Stability: Maintains 90% hardness (HB 230-260) at 300°C, with thermal expansion coefficient 12x10⁻⁶/°C, minimizing dimensional changes in heat cycles.
Alloy & Process Optimization
Alloy Composition: Increased silicon content (2.5-3.5%) enhances thermal conductivity (45 W/m·K) and oxidation resistance, suitable for heat exchanger components.
Casting Process: Resin sand molds for complex geometries (e.g., multi-passage cooling channels), with dimensional tolerance CT11-12 (ISO 8062) for critical features.
Surface & Structural Quality
Fine Surface Finish: As-cast Ra ≤12.5μm, with optional shot blasting (Ra ≤6.3μm) to improve paint adhesion and reduce aerodynamic noise.
Defect Control: 100% visual inspection and ultrasonic testing for thick-section parts (wall thickness ≥50mm), ensuring internal integrity (porosity ≤2%).
Environmental Adaptability
Corrosion Protection: Bitumen coating (100μm) or zinc-rich primer (70μm) for outdoor use, resisting atmospheric corrosion (salt spray 500h, ASTM B117).
Load Capacity: Supports static loads up to 15 tons, with tensile strength 60ksi (414MPa) and modulus of elasticity 16x10⁶ psi, ideal for heavy-duty frames.
Industrial Engines:
Cylinder heads, engine blocks, and exhaust manifolds (SAE J1999 compliant), damping vibrations and dissipating heat efficiently.
Pump Systems:
Volutes, impellers, and casings for high-temperature water pumps (ISO 2858 compliant), resisting scale formation and thermal stress.
Gearboxes:
Housing and covers for industrial gear drives, reducing noise emission by 15% compared to steel counterparts (ISO 14001:2015 compliant).
Damping Technology Expertise
Proprietary graphite morphology control increases damping capacity by 20%, validated through modal analysis (FEA) for optimal vibration reduction.
High-Temp Testing
In-house thermal cycling chambers ( -40°C to 600°C) ensure dimensional stability, providing detailed reports for temperature-sensitive applications.
Custom Solutions
Offer custom silicon/manganese formulations for specific thermal/damping requirements, with MOQ 50pcs for alloy adjustments.
Sustainable Practices
100% recycled sand for molding and water-based coatings, aligning with EU Ecolabel and ISO 14001:2015 environmental standards.
