What is a Metal?

A metal is a type of material that conducts electricity and heat relatively well. When metal is freshly crafted, polished, or fractured, it exhibits a lustrous appearance. Metals are usually hammered into thin sheets (malleable) or can be drawn into wires (ductile).

Since the Bronze Age, people have been looking for new ways to develop, refine, and use metals. Until now, metal has advanced in metalworking and manufacturing processes that gave us the Industrial Revolution.

Metals usually have a high melting point and are less likely to degrade under high temperatures. Furthermore, metals are stronger, harder, and more durable than their plastic parts.

There are thousands of different types of metals out there, and each has been developed for very specific applications. We bring you an interesting guide that will help you get to know some of these common metals and where they are used.

#1 Steel

Steel - Types of Metals

Steel is a type of alloy of several chemical elements that are made of iron with carbon to improve its strength and fracture resistance. It consists of iron and carbon with higher carbon content up to a maximum of 2%.

Steel is the most widely used material for building infrastructure and industries in the world. It is commonly used to make everything from sewing needles to oil tankers. Since it has high tensile strength and low cost, steel is used in buildings, instruments, cars, machines, electrical equipment, and weapons.

#2 Carbon Steel

Carbon Steel - Types of Metals

Carbon steel is defined as steel that has its properties mainly due to its carbon content and does not contain more than 0.5% of silicon and 1.5% manganese. It is the basic steel that contains carbon and iron, although some other elements may be added in very small amounts.

It is divided into three categories which are low, medium, and high carbon steel. More carbon means harder and stronger, whereas less carbon means cheaper and softer. A common use of this steel is for knife making due to its high carbon content, which helps the blade retain more edge.

#3 Alloy Steel

Alloy Steel - Types of Metals

It is the steel that has elements other than carbon added in sufficient quantity, in order to obtain special properties for the metal, which is known as alloy steel. These alloying elements include manganese, vanadium, chromium, nickel, and tungsten.

It is generally done to increase its strength, hardness, toughness, resistance to abrasion and wear and to improve electrical as well as magnetic properties. It is an extremely common type of metal because it is still very cheap to make. This steel is used to make pipes, especially for energy-related applications.

#4 Stainless Steel

Stainless Steel - Types of Metals

It is defined as that steel when directly heat-treated and finished resists oxidation and corroding from corrosive media. It is also known as rust-free steel because it contains a minimum of about 11% chromium that prevents iron from rusting and also provides heat-resistant properties.

The various types of stainless steel include the elements carbon, nitrogen, silicon, sulfur, titanium, copper, and more. Use of stainless steel is commonly found in kitchen tools, knives, tables, utensils, and anything that comes into contact with food. In addition, they have also used highly stress fittings such as bars, sheets, and wires in engines and machines.

#5 Iron

Iron - Types of Metals

Iron is a chemical element that is represented as the symbol Fe. It comes in the first transition series and group 8 of the periodic table. Even though it’s a super old-fashioned metal during the “Iron Age,” it still has plenty of modern uses.

Iron is the most commonly used and cheapest metal on Earth. Iron is further classified into three types which are pig iron, cast iron, and wrought iron.

#6 Pig Iron

Pig Iron - Types of Metals

It is a crude form of iron and is used as a raw material for the production of various other ferrous metals, such as cast iron, wrought iron, and steel. These irons are gained by smelting raw iron ores in a blast furnace.

Pig iron has a very high carbon content of 3.8–4.7%, with silica and other components of the aggregate. This makes it very brittle and not directly useful as a material except in limited applications. The common use of this iron is found in an electric arc furnace which is for making steel.

#7 Cast Iron

Cast Iron - Types of Metals

Cast iron is obtained by further melting pig iron with coke and limestone in a furnace called a cupola. It is the primary allow of iron and carbon. The carbon contents in cast iron vary from 1.7% to 4.5%.

In addition, it also contains a small amount of silicon, manganese, phosphorus, and sulfur. Since it is a brittle material, therefore it cannot be used in parts that are subject to shock. The cast iron provides good casting properties, high strength, wear-resistance, and low cost.

#8 Wrought Iron

Wrought Iron - Types of Metals

It is a type of iron alloy that has a very low carbon content of about 0.08%, unlike cast iron. Wrought iron offers many mechanical properties such as toughness, ductility, ductility, and corrosion-resistant. Plus, they are easily welded but are more difficult to weld electrically.

These types of metals are highly purified metals, with small amounts of silicate slag being moulded into the filaments. The presence of slag can be beneficial for blacksmithing jobs such as forging. They are used to make many products such as guard rails, garden furniture, and gates.

#9 Aluminum

Aluminum - Types of Metals

Aluminum is a type of metal with the symbol Al and atomic number 13. It is a bluish-white, light metal having a specific gravity of 2.7 and a melting point is 658°C. The density of the metal is lower than that of other common metals, about one-third that of steel.
