One of the most fundamental yet critical areas of metallurgy relates to the extracting of metals from ores, concentrates, scrap and other sources with a view to refining to the liquid state. The different compositions and uses of ferrous and nonferrous metals are vast. A form of iron, steel is one of the ferrous metals that contain less carbon than cast iron, but considerably more than wrought iron. Nonferrous metals are metals that do not have any iron in them at all.
Ferrous and nonferrous metals are two different types of metals. A force is generated perpendicular to the magnet spinning axis fig. An alloy is a mixture of two or more metallic elements, which retains its metallic bonding character. What is the difference between ferrous and nonferrous metal. The nonmetals are either solids or gases except bromine which is a liquid. This means that nonferrous metals are not attracted to a magnet and they also do not rust in the same way when exposed to moisture. Nonferrous metals advantages make them usable in many applications instead or iron and steel. For this purpose, bauxite is fused in electric furnace and carbon is added. This can be a disadvantage since it excludes this metal from any application where magnetism is necessary or is an advantage.
A few examples where the magnetic attraction of metals is used are in computer disc drives, automotive starters, audio speakers, microphone. The ferrous nonferrous materials textbook is a great resource to gain a broader understanding of ferrous materials such as the different types. Nonferrous metals include aluminum, copper, lead, zinc and tin, as well as precious metals like gold and silver. Od1643 us army correspondence course program 6 credit hours general the purpose of this subcourse is to introduce the student to the properties of metals, their. The process therefore, is to separate aluminum oxide from these impurities. Al, mg, be, ca, sr, ba b with low melting temperature alkali metals. Ferrous word has been derived from the latin word ferrum which means contains iron. An alloy is a mixture of two or more elements eg, iron and carbon to make another metal with particular.
The metals other than iron and alloys that do not contain an appreciable amount of ferrous iron are known as nonferrous metals. We are also an authorised vehicle depollution processor, we have an onsite depollution plant where we safely remove substances that are harmful to the environment before scrapping cars and other vehicles. Introduction to nonferrous metal extraction 0116 1. Heres a comprehensive list of ferrous metals and their. Aluminum aluminum ore is found as a hydrated aluminum oxide, called bauxite. A nonferrous alloy is an alloy which does not contain iron. Ferrous and nonferrous metals chemical composition and. Aluminum al used to make everything from aluminum foil to airplane parts. All these alloys share the same two basic nonferrous qualities with their base metallic components indifference towards magnets and. This lesson will define ferrous metals, list some of their properties, and then conclude with examples. A pure metal is an element eg iron, copper, gold unalloyed not mixed with another substance. The impurities present in it are oxides of iron, silicon, and titanium. Nonferrous aircraft metals the term nonferrous refers to all metals that have elements other than iron as their principal constituent.
Once we have made the distinction, we can look at their different properties. These metals are generally magnetic in nature and have a high tensile strength. In the present, their role in the engineering industries can be easily described as most dominating. Ferrous metals are those which contain iron as their main constituent or base metal.
