Metals and Alloys

Metals are one of the most important and commonly used types of engineering materials. They have a wide range of physical and mechanical properties, such as high strength, ductility, thermal and electrical conductivity. Some metals also provide resistance to corrosion. Due to their unique combination of properties, metals are widely used in a variety of industries and applications, including construction, transportation, electronics, and manufacturing. In addition, metals can be easily formed and fabricated into various shapes and sizes using different processes, such as casting, forging, and extrusion.

An alloy is a mixture of a metal with either a non-metal or another metal. Alloys are typically created to enhance the properties of the original metal, such as increased strength or improved corrosion resistance. By combining different metals, an alloy can have a unique combination of properties that make it suitable for specific applications. Alloys are widely used in engineering due to their favorable properties, and many common engineering materials are alloys. Examples of common alloys include steel, which is an alloy of iron and carbon, and brass, which is an alloy of copper and zinc.

Metals and Alloys

Metals are one of the most commonly used engineering materials.

Ferrous Metals

Ferrous Metals
Ferrous metals are a category of metals that contain iron as their main constituent element. The most common ferrous metals include carbon steel, alloy steel, stainless steel, cast iron, and wrought iron. These materials are widely used in engineering applications due to their high tensile strength, durability, and resistance to wear and tear. Additionally, ferrous...

Nonferrous Metals

Nonferrous Metals
Nonferrous metals are metals that do not contain iron as a major component. These metals have different properties and applications compared to ferrous metals. Common nonferrous metals include aluminum, copper, zinc, nickel, and titanium, among others. Nonferrous metals such as aluminum are extremely useful engineering materials. One of the most notable advantages of nonferrous metals...

Atomic Structure of Metals

Atomic Structure of Metals
Metals represent a class of chemical elements defined by distinctive characteristics. They are recognized for their metallic luster, high electrical conductivity, malleability, and ductility. hat sets metals apart is their ability to readily relinquish electrons, forming positively charged cations within their crystalline atomic structure. These cations are held together by metallic bonds, where the outermost...

ASM International

ASM International, formerly known as the American Society for Metals, is a professional organization focused on materials science and engineering. It was originally founded in 1913 as the Steel Treaters Club and later became the American Society for Steel Treating in 1920. Over the years, its scope expanded beyond just steel to include all materials,...
