Comparing Gray Iron and Ductile Iron Castings for Machine Tool Components
Machine tools demand structural stability, vibration control, and long-term dimensional accuracy. Whether used in CNC machining centers, lathes, milling machines, or grinding equipment, core structural components—such as beds, columns, housings, and bases—must maintain rigidity under load while minimizing vibration during operation.Among the most widely used materials for machine tool castings are gray iron and ductile iron. Although both belong to the cast iron family, their mechanical properties and performance characteristics differ significantly. Choosing the right material depends on application requirements, structural design, and service conditions.Manufacturers such as Casteks Metal Science (Jiangsu) Co., Ltd. have accumulated extensive experience in producing high-quality iro...
