Metals are used in a large number of industries. There are many types of metals in the world. They include aluminum, gold, copper, steel, silver, platinum, nickel, lead, zinc, and mercury. All these metals have various properties which make them suitable for different applications.
Some metals can withstand extreme conditions, while others can be found in any home or workplace.
The metals in our world are a key part of running our lives. You probably wouldn’t be reading this if it weren’t for the metals we use daily to run our electronics and appliances.
In this article, you will learn about the strongest metals on earth, including their properties and uses.
What Makes a Metal Strong?
There are a few factors that contribute to the strength of a metal. These include:
- Density: This is the measure of how much mass is in a given volume. A higher density means more mass in a given volume, making the metal stronger.
- Hardness: This is a measure of how resistant the metal is to scratching, denting, and other forms of damage. A harder metal will be more resistant to damage.
- Young’s modulus: This is a measure of the metal’s stiffness. A higher Young’s modulus means the metal is less likely to deform under stress.
- Melting point: This is the temperature at which the metal will melt. A higher melting point means the metal can withstand higher temperatures before melting.
