Updated on: September 25th, 2023

(A) Gold

(B) Iron

(C) Platinum

(D) Tungsten

Tungsten is the hardest metal. On the Moh’s hardness scale, the mineral’s hardness is described. A mineral’s strength is evaluated on this scale from 1 to 10, with 10 being the strongest. Not just metals but also other materials and elements are rated according to their degree of hardness. It rates materials according to their hardness, with 1 being the hardest and 10 being the softest.

Moh’s scale of Various Minerals

  • The sturdiest metal is tungsten.
  • The metal platinum is less hard. It is utilized in jewellery as a result. It’s able to create complex patterns. It has great ductility.
  • Tungsten gets its name from the Swedish word tungsten, which means hefty stone.

The capacity to scratch and denting the metal’s surface is hardness. It is merely a measurement made using the (Rockwell, Brinell, and Vickers tests), with Brinell being the most accurate.

  1. Gold – 25 Mpa
  2. Tungsten: 310 Mpa
  3. Platinum: 40 Mpa
  4. Diamond: 10000 Mpa 
  5. Iron: 150 Mpa
  • The strongest metal in the world, according to tensile strength, is an atomic number 74 chemical element. W is its symbol.
  • The strength and durability of tungsten increase when coupled with carbon. The result of combining tungsten and carbon is tungsten carbide. With a Mohs hardness value of 9, tungsten carbide is 4 times stronger than platinum and only slightly softer than diamond.
  • From the above, 310 > 40, So, Tungsten is harder than Platinum.


Which of the following is the hardest metal? (A) Gold (B) Iron (C) Platinum (D) Tungsten

Tungsten is the hardest metal. Tensile strength indicates that an element with atomic number 74 is the strongest metal in existence. Its emblem is W. In the above options, the hardest metal is Tungsten only.
