Comparison of Cast Iron Types

Property GRAY CAST IRON – DIN EN 1561 SPHEROIDAL CAST IRON – DIN EN 1563 NEW GENERATION SPHEROIDAL CAST IRON (SSF)
Definition Due to its gray graphite structure, it is a low-strength material with high vibration-damping properties. With its globular graphite structure, it is a high-strength, elastic, and durable material. Strengthened with technological advancements, it is a high-strength and durable material.
Main Areas of Use Engine blocks, brake discs, pump housings, machine frames. Automotive parts (crankshaft, axle housing), machine parts, railway components. Automotive industry (engine parts), machinery manufacturing, infrastructure projects.
Mechanisms and Structure Low strength, machinability, and vibration damping. High tensile and impact resistance, flexibility, corrosion resistance. Advanced alloys, low weight, high durability.
Advantages Low cost, high machinability, good vibration damping capability. High tensile and impact resistance, corrosion resistance, weldability. Higher strength, long lifespan, environmentally friendly production.
Classification Standards Classes such as EN-GJL-150, EN-GJL-200, EN-GJL-300. EN-GJS-400-15, EN-GJS-500-7, EN-GJS-600-3, EN-GJS-700-2. Optimized new alloys and advanced manufacturing techniques.
Quality Standards Produced with ISO 9001, TS EN 1561 certifications. ISO 9001, TS EN 1563, ASTM A536 quality standards. ISO 9001, TS EN 1563, environmentally friendly production conditions.
Similarities Preferred as an alternative to spheroidal cast iron in low-cost part production. Shares common structural features with new generation spheroidal cast iron. Shows high performance similarities with spheroidal cast iron as its advanced version.
