Ductile cast iron is a special form of cast iron, which has high ductility and toughness by adding different proportions of magnesium and rare earth elements in the casting process. It inherits the advantages of traditional cast iron, such as excellent fluidity, low melting point and high wear resistance, while overcoming its shortcomings of brittleness and easy fracture. This makes cast iron an ideal choice in all fields.

Ductile Iron Castings from Qingdao TianHua Ductile iron has a long history – it was created in World War II. Ductile iron castings offer excellent surface finish, have a better strength to weight ratio as compared to ferrous alloys, are corrosion resistant and can be machined precisely.Ductile Iron

Ductile Iron Material Grades Choosing Guide This guide will help you to choose the suitable ductile iron material grades.You know that the foundry should use ductile iron to produce the castings for you, but actually, there are several different material grades.

Some customers of Qingdao TianHua YiHe foundry asked us about the difference between cast iron and ductile iron, including their advantages and disadvantages. Here in, we listed their main properties and hope to give you a reference for material selection. Actually, before comparison, we need to clarify a definition. The cast iron is meaning a category of iron material, whose carbon content is higher than 2.1%. Therefore, it includes many different types according to different graphite shapes and microstructures, such as grey iron, ductile iron, white iron, malleable iron, vermicular iron, austenitic iron etc.
