Non-ferrous metals also include brass, gold, nickel, silver, tin, lead, and zinc. The processes for ferrous metal recycling and non-ferrous metal recycling differ due to the different properties of these metals. Can be hardened and tempered. Aluminum is highly resistant to corrosion. Standard nonferrous metals are aluminum, copper, lead, nickel, tin, and zinc and their alloys. Because of low carbon content it can not be hardened and tempered. Ferrous metals are known for their tensile strength and durability and their characteristics recognized by their use in tall buildings and long bridges. This makes them ideal for an extensive range of commercial industries. Iron 99.9 - 99.7%: Tough. This was roughly around 1,200 B.C. Ferrous metals have a relatively low melting point, depending on the levels of carbon within the metal. Some examples of non-ferrous metals are aluminum, aluminum alloys, and copper, which are often used in industrial applications such as gutters, roofing, pipes, and electrical. Alloy metals such as Duralumin (which is composed of a combination of copper and manganese in a 4:1 ratio besides aluminum), brass (which is 35% zinc and 65% copper) and Gliding metal (an alloy of 15% zinc and 85% copper) are some of the most prominent non-ferrous metal examples that are made by combining two or more other non-ferrous base metals. Ferrous metals: Ferrous metals are metals that consist mostly of iron and small amounts of other elements. Copper, Brass and Bronze, otherwise known as the “Red Metals”, may look the same initially but are actually quite different. Carbon Steel: Carbon 0.6 - 1.4%. when iron production really took off. All types of steel and iron are ferrous metals. Of the non-ferrous metals, copper is one of the most widely recycled, closely followed by … This means that they are particularly easy to recycle. Most ferrous metals also have magnetic properties and are used in electrical applications. Ferrous metals may contain small amounts of other elements such as carbon or nickel, that are added (in a specific proportion) to achieve the desired properties. Lesson 9 Flowcharts: Lesson10 vacuumforming: Lesson11 Quality : Lesson 12 Finishes : Ferrous and Non-Ferrous MetalsTable . Cutting … Aluminum: Aluminum is mainly obtained from bauxite ore. Aluminum is a very common component (about 8 percent ) of the earth crust, the most common ore of aluminum is Bauxite (Al 2 O 3. n H 2 O). All the commercial forms of iron and steel contain some amount of carbon and is an integral part of iron & steel metallurgy. Metals that can be case hardened are generally limited to ferrous materials, although there are special cases such as the nitriding of some titanium or aluminium alloys. Can be case hardened. Non-ferrous metals have quite extensive uses as their properties tend to be quite desirable: low weight, high conductivity, non-magnetic and corrosion resistance. Copper is used in a wide range of products due to its excellent electrical and thermal conductivity, good strength, good formability and resistance to corrosion. Iron and steel in all forms are viewed as ferrous metals, while metals that don’t constitute an iron component in them are termed as non-ferrous. Ferrous metals are, therefore, those that consist mainly of iron (Fe).These metals may also contain one or more other alloying elements. Non-ferrous" is used to describe metals and alloys that do not contain an appreciable amount of iron. However, wrought iron – which is a ferrous metal – tends to resist rust due to the fact that it contains so much iron. Copper. Rusts very easily. As atoms transform from one specific arrangement, or crystal lattice, to another, strength, toughness, impact resistance, hardness, ductility, and other properties are altered. Ferrous metals have some well-known properties. Typical ferrous metals include mild steel, cast iron and steel. This feature makes them an excellent choice for construction materials, either structural or design. Generally these are more costly than the ferrous metals. Types of Ferrous Metals. They are durable and known for their tensile strength, so they’re used in construction, cars, rail and tools. Ferrous metals are prone to rusting if exposed to moisture. Cast Iron: Hard skin, softer underneath, but brittle, corrodes as it oxidizes; Mild steel: Hard, ductile, malleable, good tensile strength, low corrosion resistance. Most common metal used in school workshops. FERROUS METALS PROPERTIES OF IRON Cast iron has a carbon content higher than 2.1%. Ferrous metals are also usually very strong and rust resistant. Ferrous metals include steel and pig iron (with a carbon content of a few percent) and alloys of iron with other metals (such as stainless steel).
