Ductile Iron Casting Part Series 1
JHshukong
Designed for automotive powertrain, chassis and electric vehicle (EV) structural systems, our ductile iron casting parts offer a lightweight, cost-effective alternative to forged steel for global automotive manufacturing enterprises. Cast from premium ASTM A536 Grade 65-45-12 and EN-GJS-400-18 ductile iron, our high yield strength ductile iron castings deliver exceptional mechanical performance, combining superior load-bearing capacity with excellent formability to meet the rigorous demands of passenger vehicles, commercial trucks and EV OEMs. Through spheroidized and inoculated graphite treatment, our crash resistant EV ductile iron components improve the plasticity and toughness of cast iron, achieving strength comparable to carbon steel while enabling significant weight reduction to enhance vehicle fuel efficiency and EV driving range.
Our automotive ductile iron castings set a benchmark for automotive-grade performance, with industry-leading yield strength of 310MPa (45ksi), 20% higher than standard ductile iron, ideal for load-bearing applications such as suspension arms and steering knuckles. With elongation ≥12%, the castings support cold forming and excellent crash energy absorption, a critical feature for safety-compliant automotive components meeting FMVSS 208 standards. Our optimized production delivers a ferritic matrix (≥90%) with nodular graphite size ≥8 (ISO 945), enhancing fatigue life to 10⁸ cycles at 120MPa for wheel hubs and brake calipers. We also lead in thin-wall casting technology, successfully casting 3-5mm thin walls to achieve 25% weight reduction compared to gray iron without compromising strength. Through 3D-printed cores and CAE optimization, we produce ribbed structures and hollow sections for lightweight EV battery mounts and chassis components, supporting the lightweighting goals of our automotive business clients.
