Cast Iron GGG40 - Ductile IronCast iron GGG40 is a low grade of ductile iron. Our foundry has produced this material for many years, and herein, we introduce its mechanical and chemical properties and some iron castings made by this material grade. GGG40 is a ductile iron grade of Germany standa
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.
We will compare cast iron and carbon steel from mechanical and physical properties.Cast iron includes gray iron and ductile iron. Gray iron is cheaper than ductile iron, but it has much lower tensile strength and ductility than ductile iron, so gray iron is not replaceable material for carbon steel.
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.
Non-ferrous casting usually refers to removal of iron (including manganese, chromium and ferro alloys) of metal casting processes. The common materials for non ferrous casting: copper, lead, zinc, aluminum, magnesium, etc. Non ferrous castings are widely used in military, high-speed rail, ship, engineering machinery, pump, semiconductor equipment, wind power, power station and electrical equipment and so on.
The investment casting is also called lost wax casting. It’s generally used for custom complicated shape casting parts which cannot be reached by die casting or sand casting. It can made from almost any metal, especially stainless steel. The casted parts weight from grams to kilograms.
