What is the difference between Ferrous Vs Non-Ferrous metals
The Simple response is that non-ferrous metals do not contain iron while ferrous metals do. The more thorough response is that both ferrous and non-ferrous metals have unique characteristics of their own. The applications they are best suited for are determined by these characteristics.
Metals that are not ferrous have been utilized since the dawn of civilisation. The Stone Age came to an end and the Copper Age began with the discovery of copper approximately 5,000 BC. The Bronze Age began with the creation of bronze, a copper and tin alloy.
When iron production became widespread around 1,000 BC, people first began to employ ferrous metals. The Iron Age started as a result.
Which Metals Are Ferrous?
Iron, cast iron, wrought iron, alloy steel, and carbon steel are some typical ferrous metals. Because of their tensile strength and longevity, these metals are highly valued. The tallest skyscrapers and longest bridges are made of carbon steel, also known as structure steel, which is a mainstay in the construction sector. Ferrous metals are also utilized in numerous industrial and residential appliances, cars, railroad lines, shipping containers, and industrial piping.
Ferrous metals typically rust easily when exposed to moisture because of their high carbon content. There are two exceptions to this rule: stainless steel is shielded from rust by the presence of chromium, and wrought iron is resistant to rust due to its purity.
The fact that most ferrous metals are magnetic makes them ideal for use in electrical and motor applications. Your refrigerator door's use of ferrous metals enables you to use a magnet to attach your shopping list to it.
Compared to other varieties of steel, carbon steel has a higher carbon content, making it more harder. In the production of machine tools, drills, blades, taps, and springs, it is frequently employed. It is able to maintain a cutting edge.
Chromium, nickel, and titanium are among the metals added to steel alloys to increase strength and durability without adding weight. An essential alloy steel manufactured with chromium is stainless steel. Electrical components, machine tools, and construction all require alloy steels.
Iron is produced into steel by mixing it with carbon, which makes iron harder. As additional components like nickel and chromium are added, alloy steel becomes even more durable. Iron ore is heated and melted in furnaces to create steel. To create steel bars, the steel can is tapped out of the furnaces and poured into molds. Steel is frequently utilized in the manufacturing and construction sectors.
An alloy of silicon, carbon, and iron is known as cast iron. Cast iron is tough, brittle, and wear-resistant. It is utilized in stoves, machine tools, car engines, and water pipes.
The alloy used to make wrought iron contains so little carbon that it is practically entirely iron. Slag is used into the manufacturing process to offer wrought iron superior corrosion and oxidation resistance, but low hardness and fatigue strength. Fencing, railings, agricultural equipment, nails, barbed wire, chains, and a variety of ornamentation are all made of wrought iron.
Which Metals Are Non-Ferrous?
Aluminum, copper, lead, zinc, and tin are examples of non-ferrous metals, as are precious metals like gold and silver. Their malleability gives them a significant edge over ferrous materials. They are perfect for gutters, liquid pipelines, roofs, and outdoor signage because they also contain no iron, which increases their resistance to rust and corrosion. Last but not least, they are non-magnetic, which is crucial for many electrical and electronic applications.
Tin is ductile, exceedingly soft, and has a low tensile strength. Steel is frequently coated with it to stop corrosion. Tin cans used to hold food are made of tinplate steel. Tin foil was frequently employed to wrap food products in the late 19th century, but aluminum foil has since largely taken its place. Tin brass and bronze can be created by alloying tin with copper.
Aluminum is weak, lightweight, and squishy. Aluminum is simple to forge, machine, weld, and cast. Environments with high temperatures are not suitable for it. Aluminum is a fantastic material to utilize when making food cans and aircraft since it is lightweight. Additionally, castings, pistons, automobiles, trains, and kitchenware are all made of aluminum.
Low melting point, heavy, pliable, squishy, and with low tensile strength is lead. It is resistant to corrosion caused by numerous acids and moisture. Lead is a common material used in soldering, batteries, electrical power connections, and building construction.
Copper is a red metal with excellent malleability, great ductility, and high conductivity for both electricity and heat. Wire and other conductors made of copper are mostly used in the electrical industry. Additionally, it is utilized in bearings, laws, cartridge cases, and sheet roofing. Brass, an alloy of copper and zinc, is also made from copper.
Zinc has a very low melting point and a modest to low strength. It is easily machined, however heating might be necessary to prevent crystal cleavage. The most common application of zinc is in galvanizing, which is the process of covering iron or steel with a protective zinc layer to stop rust.
