Titanium versus Tungsten: Determining Which Is Strongest

Have you ever wondered which are some of the strongest metals on Earth? Titanium and tungsten would be the two most likely candidates.
But which one of these is the strongest? To answer that we need to begin by defining what we mean by “strong”. Strong material is one that, according to materials science, “resists both deformation and failure.”
In this video, when defining "strength" we took into account the following traits: Scratch resistance, Brittleness, Ductility, and Tensile strength. However, determining which one was the strongest proved a complicated task exacerbated by the fact that it is rare that these pure metals are used alone.
Indeed, both tungsten and titanium are usually alloyed with other metals to make them more workable. That's how tough they really are! Alone, they can not be easily manipulated.
So, it's essential to note that for the purposes of this video we are looking at metal alloys, not the pure metals themselves. For tungsten, we are looking at a combination with carbide called tungsten carbide.
For titanium, we are looking at a combination of metals like aluminum or vanadium. Which of these alloys is indeed the strongest? Watch our video to find out more.
