Types of castings and forgings can be divided according to different classification standards.
Classification by metal materials used:
Steel castings: used to manufacture parts that require higher strength.
Iron castings: widely used in various machinery and equipment because of their low cost and good casting properties.
Copper castings, aluminum castings, magnesium castings, zinc castings, titanium castings: suitable for specific environments and application requirements.
Classification by chemical composition or metallographic structure:
Gray iron castings, ductile iron castings, vermicular iron castings, malleable iron castings, alloy iron castings: subdivided according to different chemical compositions and metallographic structures.
Classification by casting molding method:
Ordinary sand castings: the most widely used, accounting for about 80% of the total casting output.
Metal mold castings, die castings, centrifugal castings, continuous pouring, investment castings, ceramic mold castings, electroslag remelting castings, bimetallic castings: These methods are suitable for different production needs and product characteristics.
