What’s The Difference Between Ferrous and Non-Ferrous Metal?

The simple answer is that ferrous metals contain iron and non-ferrous metals do not. The more in-depth answer is that ferrous metals and non-ferrous metals each have their own distinctive properties. These properties determine the applications they are most suited for.
Non-ferrous metals have been used since the beginning of civilization. The discovery of copper in 5,000 BC marked the end of the Stone Age and the beginning of the Copper Age. The later invention of bronze, an alloy of copper and tin, started the Bronze Age.
The use of ferrous metals started in around 1,200 BC when iron production started to become commonplace. This ushered in the Iron Age.

Which Metals Are Ferrous?

Some common ferrous metals include alloy steel, carbon steel, cast iron and wrought iron. These metals are prized for their tensile strength and durability. Carbon Steel – also known as structure steel – is a staple in the construction industry and is used in the tallest skyscrapers and longest bridges. Ferrous metals are also used in shipping containers, industrial piping, automobiles, railroad tracks, and many commercial and domestic tools.
Ferrous metals have a high carbon content which generally makes them vulnerable to rust when exposed to moisture. There are two exceptions to this rule: wrought iron resists rust due to its purity and stainless steel is protected from rust by the presence of chromium.
Most ferrous metals are magnetic which makes them very useful for motor and electrical applications. The use of ferrous metals in your refrigerator door allows you to pin your shopping list on it with a magnet.

Steel

Steel is made by adding iron to carbon which hardens the iron. Alloy steel becomes even tougher as other elements like chromium and nickel are introduced. Steel is made by heating and melting iron ore in furnaces. The steel can is tapped from the furnaces and poured into molds to form steel bars. Steel is widely used in the construction and manufacturing industries.

Carbon Steel

Carbon steel has a higher carbon content in comparison to other types of steel making it exceptionally hard. It is commonly used in the manufacturing of machine tools, drills, blades, taps, and springs. It can keep a sharp cutting edge.

Alloy Steel

Alloy steels incorporate elements such as chromium, nickel and titanium to impart greater strength and durability without increasing weight. Stainless steel is an important alloy steel made using chromium. Alloy steels are used in construction, machine tools, and electrical components.

Cast Iron

Cast iron is an alloy made from iron, carbon, and silicon. Cast iron is brittle and hard and resistant to wear. It’s used in water pipes, machine tools, automobile engines and stoves.

Wrought Iron

Wrought iron is an alloy with so little carbon content it’s almost pure iron. During the manufacturing process, some slag is added which gives wrought iron excellent resistance to corrosion and oxidation, however, it is low in hardness and fatigue strength. Wrought iron is used for fencing and railings, agricultural implements, nails, barbed wire, chains, and various ornaments.

Which Metals Are Non-Ferrous?

Non-ferrous metals include aluminum, copper, lead, zinc and tin, as well as precious metals like gold and silver. Their main advantage over ferrous materials is their malleability. They also have no iron content, giving them a higher resistance to rust and corrosion, and making them ideal for gutters, liquid pipes, roofing and outdoor signs. Lastly they are non-magnetic, which is important for many electronic and wiring applications.

Aluminum

Aluminum is lightweight, soft and low strength. Aluminum is easily cast, forged, machined and welded. It’s not suitable for high-temperature environments. Because aluminum is lightweight, it is a good choice for the manufacturing of aircraft and food cans. Aluminum is also used in castings, pistons, railways, cars, and kitchen utensils.

Copper

Copper is red in color, highly ductile, malleable and has high conductivity for electricity and heat. Copper is principally used in the electrical industry in the form of wire and other conductors. It’s also used in sheet roofing, cartridge cases, statutes, and bearings. Copper is also used to make brass, an alloy of copper and zinc.

Lead

Lead is a soft, heavy, malleable metal with a low melting point and low tensile strength. It can withstand corrosion from moisture and many acids. Lead is widely used in electrical power cables, batteries, building construction and soldering.

Zinc

Zinc is a medium to low strength metal with a very low melting point. It can be machined easily, but heating may be required to avoid cleavage of crystals. Zinc is most widely used in galvanizing, the process of applying a protective zinc coating to iron or steel to prevent rust.

Tin


Tin is very soft and malleable, ductile with low tensile strength. It’s often used to coat steel to prevent corrosion. Tinplate steel is used to make tin cans to hold food. In the late 19th century, tin foil was commonly used to wrap food products, but has since largely been replaced by aluminum foil. Tin can also be alloyed with copper to produce tin brass and bronze.

Team Work - Meaning and Tips for better Team Work

By
A single brain is not always capable of making key decisions on its own. To come up with an efficient solution, an individual requires the help and advice of others. A team is established when individuals get together on a common platform with the common goal of completing a task. To guarantee optimum compatibility, team members should ideally come from similar backgrounds and have a single aim. To provide their best, the team members must complement each other and function as a single unit in tight cooperation. "There is no I in Team Work," as the saying goes, and each member must put the needs of his team first. Personal interests must take a second seat. Any team's performance is directly proportionate to the relationship between its members and their combined efforts. What is the definition of teamwork? Teamwork is defined as the sum of each team member's efforts toward the fulfilment of the team's goal. In other words, any team's backbone is its ability t

Scientists discover a new theory / The fundamental property of light – 150 years after Maxwell

By
Light plays a vital role in our everyday lives and technologies based on light are all around us. So we might expect that our understanding of light is pretty settled. But scientists have just uncovered a new fundamental property of light that gives new insight into the 150-year-old classical theory of electromagnetism and which could lead to applications manipulating light at the nanoscale. It is unusual for a pure-theory physics paper to make it into the journal Science. So when one does, it’s worth a closer look. In the new study, researchers bring together one of physics' most venerable set of equations – those of James Clerk’s Maxwell’s famous theory of light – with one of the hot topics in modern solid-state physics: the quantum spin Hall effect and topological insulators . To understand what the fuss is about, let’s first consider the behaviour of electrons in the quantum spin Hall effect. Electrons possess an intrinsic spin as if they were tiny spinning-tops,
