As a materials science expert with a focus on metallurgy, I can tell you that the concept of the "hardest metal" can be a bit misleading because hardness can be measured in different ways and depends on the context in which the metal is used. However, when it comes to pure metals, chromium is often considered one of the hardest, with a hardness of approximately 900 on the Vickers hardness scale.
Chromium is highly resistant to corrosion and is known for its hardness and ability to be highly polished. It's widely used for plating other metals to increase their corrosion resistance and to give a shiny, reflective finish.
Another metal that is often mentioned in discussions about hardness is tungsten, which has the highest tensile strength among metals and is very hard. Tungsten's hardness is around 800-900 on the Vickers scale, and it's used in applications that require high strength and resistance to deformation.
It's important to note that there are also metal alloys that can be even harder than pure metals. For example, cemented carbides, which are composed of tungsten carbide and a binder metal (usually cobalt), are extremely hard and are used for cutting and grinding tools.
In summary, while chromium and tungsten are among the hardest pure metals, the hardness of a metal can be significantly enhanced through alloying and other treatments.
