Which is Harder, Platinum or Tungsten?

Whether it’s for jewellery or industrial parts, many people are looking for beautiful and sturdy metal. Two of the most popular choices are platinum and tungsten. But which one is tougher? Let’s compare the durability of these two metals to find out.


When comparing hardness, tungsten wins hands down—it is one of the hardest metals on earth and even ranks higher than diamond on the Mohs scale. However, it is essential to note that this does not necessarily mean that it is more durable than platinum. Tungsten can be brittle; when enough force is applied, it can crack or shatter.

Platinum, however, may not be as hard as tungsten, but it has greater malleability. This means that it can bend without breaking—so while it may scratch or dent over time, its shape will remain intact even after years of use. It also has a higher melting point than tungsten, so it can withstand higher temperatures without warping or melting.

Resistance to Corrosion

Both platinum and tungsten have excellent corrosion resistance; however, platinum also takes the edge because its white luster does not fade over time like some other metals do when exposed to air and moisture. This makes platinum an ideal choice for jewellery since its beauty won’t diminish with age. On the other hand, while tungsten is extremely resistant to corrosion, its black colour tends to dull over time due to contact with oxygen in the air.


When deciding between platinum and tungsten for your next project or purchase, please consider their different hardness and corrosion resistance levels. While both metals are incredibly durable in their own right—and each has unique benefits depending on your needs—platinum offers superior malleability and corrosion resistance compared to tungsten, making it an ideal choice for jewellery or any application where long-term durability matters most. Ultimately though, only you can decide which metal best fits your needs!
