Cupola furnace is cylindrical in shape with an almost uniform diameter (about 1 meter) and a height of about 5 to 6 meters. In all the jobs ranging from the manufacture of a primitive type of agricultural implements to advanced types of Air Crafts, ferrous metals and their alloys occupy a prominent position. Used in manufacturing of cisterns, sewer and drain pipes, manhole covers and fittings. Some examples are chromium, nickel, molybdenum, vanadium, manganese. The slag is removed intermittently through the hole and molten metal taken out through its tap hole. Its Types, Parts Used in Construction. The molten metal taken out are fed into the molds prepared to get desired shapes. Pure Iron is of little use as an engineering material because it is too soft and ductile. Those give ferrous steels mechanical properties that make them widely used in engineering. Even though almost all this types of nonferrous metals are costly than ferrous metals, they are used in industrial application such as: roofing pipes, electrical and gutters. 2. copper), low weight (e.g. Ferrous metallurgy represents roughly 90% of worldwide production of metal. Alloyed Cast Irons are produced by adding the alloying elements to the Pig Iron in the cupola furnace itself or adding the same into the molten Cast Iron taken out of the furnace. According to ASTM ferrous metal designation system, “A” describes a ferrous metal such as A106, "A" prefix indicates that this material is ferrous material. Types of Metal Finishing. But if elements are added other than Iron and carbon, the Steel is known as alloy Steel. 9. In the present, their role in the engineering industries can be easily described as “most dominating.”. 5. It is also called forge Pig Iron, as it is hard and brittle and can be converted only by using pressure. Non-Ferrous Metals; Types, Uses, Properties [Complete Guide] The process is much cheaper than producing new metal from the basic ore. Steel is a versatile material of modern age. 2. This is the first major group of Steels. Recycling - Recycling - Ferrous metals: Ferrous products (i.e., iron and steel) can be recycled by both internal and external methods. Please, don’t forget to share it. The wide abundance of Iron ore in almost all parts of the world. It is a modified Grey Cast Iron. On the other hand, with the decrease in the carbon content (lower than 0.1%), the material would resemble more to Wrought Iron or pure Iron. Wrought iron. It is suitable for highly corrosive environments such as: liquid, chemical and sewage pipelines. It cannot be tempered or hardened like steel. And in any other field of engineering activity, it may not be possible to move ahead without metals. Ferrous metals are vulnerable to rust when exposed to moisture as they have a high carbon content. Outside of the foundry, steel is the ferrous … Also known as uniform attack corrosion, general attack corrosion is the most common type of corrosion and is caused by a chemical or electrochemical reaction that results in the deterioration of the entire exposed surface of a metal. It can also be classified on the basis of Steel casting. Bronze, which is an alloy of copper and tin, was likely first used around 35,000 BC. It is used for car wheels, rollers for crushing grains, crusher jaw plates, etc. The alloy Cast Irons are used for gears, sprockets, wheels, I.C engine cylinders, piston, piston rings, crankcases, crankshafts, camshaft, brake drums and shoes, parts of grinding machines, etc. zinc). Nickel is added to effect an increase in the hardness and resistance to wear. Ultimately, the metal deteriorates to the point of failure. The economic extraction of Iron from its ore. 3. If there is a free graphite present, it is a Cast Iron, otherwise a Steel. Lead. Therefore, it is also known as chilled Cast Iron. Used for making parts, bodies, and beds of machines. It is used in rolls for rolling mills, hydraulic cylinders, cylinder heads, etc. It is also used in buildings, railways, and marine industries. Ferrous Metals. The Cast Iron thus obtained is in a molten state, and it is chilled, i.e., it is cooled rapidly. It is used in Agricultural machinery making and carpentry tools. Therefore, Pig Iron is remolded in a furnace and cast or poured into molds of the desired shape to get the Iron known as Cast Iron. Cast Iron is manufactured in a furnace known as cupola furnace. Brinell hardness number of 105; tensile strength of 35,000 psi; specific gravity of 7.7; a melting point of 2750°F (1510°C); and is ductile and corrosion resistant. Non-Ferrous Metals; Types, Uses, Properties [Complete Guide]. The electrical, magnetic, and thermal properties may be modified in the desired direction. 10. Low resistance to corrosion 5. Because of the above set of properties, Wrought Iron is extensively used as a material for making plates, sheets, pipes, tubes, etc. Ferrous Metals List | Their Types and Properties: What is Paint, Definition, Properties, & Components of paints. Some internal recycling methods are obvious. Think steel, stainless steel, carbon steel, cast iron. Types Of Metals. properties. 3. It has a specific gravity of  7.5, and it has a melting point of 1250°C. It is used for hubs of wagon wheels, railway rolling stock, brake supports, parts of agricultural machinery, pipe fittings, door hinges, locks, etc. Alloy steels are a type of ferrous metal specially formulated to serve specific purposes. The definition of a ferrous metal is any metal that contains iron; non-ferrous metals do not. Pig Iron, because of its impurities, is weak and hence very... 3. It is used in Railways equipment of a great variety. Alloy Cast Irons are also called as plain Cast Irons. automotive parts: engine blocks, pistons, gearbox cases, cylinder blocks, No Alloys: Tensile strength of 25,000 to 50,000 psi (172,375 to 344,750 kPa), Alloys: 50,000 to 100,000 psi (344,750 to 689,500 kPa), Cylinder heads for compressors and diesel engines. It is used in flywheels and agricultural implements. Iron and steel are widely available, strong, cheap, and can be shaped by casting. There are far more differences than there are similarities among the different types of non-ferrous metals. Why is it that ferrous Alloys have low electrical conductivity. What is Scaffolding? The Cast Iron thus obtained, has 1.7 to 4% of carbon with small impurities of manganese, phosphorus, silicon, and sulfur. White iron. It possesses useful properties of both Cast Iron and mild Steels. Usually magnetic 4. Wrought Iron shows good resistance to fatigue and sudden shock. While composed primarily of iron, differing amounts of copper, vanadium, tungsten, manganese, and other elements can be used to tailor an alloy steel to have higher toughness, ductility, tensile strength, hardness, and other properties. i.e., in the form of cementite, also known as Iron carbide. 3. Abrasive Definition and Types of Abrasives its Forms and Applications. The ferrous metals includes all the types of Iron, Steel, and their alloys. Gray iron is the most common metal cast in foundries. It has high tensile strength, toughness, and wear resistance. It is used for automobile cylinder blocks, heads, housings, etc. We have discussed the characteristics of the different Non-ferrous metals and the purpose and use of the non-ferrous metal in different applications in this article. Examples of ferrous metals uses: Because these metals tend to be strong and durable, they have many uses in construction and engineering. If you have any questions, feel free to ask in the comment section. It is soft compared to other Cast Irons and has good machinability.

Test for Compressive Strength of Bricks, Absorption, Efflorescence & Size. Cast Iron:. Recycling steel saves a lot of energy, natural resources and reduces harmful emissions to the atmosphere as a result of ore production. This is a heavy metal that’s dull grey in color, although it becomes shiny when polished. Non-ferrous metals are those which do not contain significant quantity of iron (ferrite) or iron as the base metal. 4. Chilled cast iron. It has high tensile strength but weak compressive strength. The alloying elements used are; nickel, chromium, molybdenum, and vanadium. It has a shiny white color and a bright metallic white luster. Metal plating uses chemical baths to coat or alter the surface of substrates with thin layers of metal such as zinc, nickel, cadmium, or chromium.
