High-silicon molybdenum ductile iron

Product Use

Feature

High-silicon molybdenum ductile iron (5% silicon content) finds extensive applications in high-temperature castings

for automotive engines, particularly in exhaust systems (e.g., exhaust pipes, turbocharger housings, valve bodies, 

valve discs, etc.). This is primarily due to its excellent properties including high-temperature resistance, thermal 

fatigue performance, outstanding oxidation resistance, and good high-temperature creep resistance.


Our company has now developed precision-cast high-silicon molybdenum ductile iron valve discs, valve bodies, 

and other castings, featuring high dimensional accuracy, delicate appearance, and excellent performance, which

have been utilized in exhaust systems for heavy-duty trucks.
