Researchers have shown that a metal alloy made of chromium, cobalt, and nickel is the hardest substance on Earth. This alloy is more durable than graphene by more than a hundred times.

What are alloys?

Alloys are metals produced by combining two or more metals.

What is Graphene?

Graphene is the building block of graphite.

What is megapascal?

A basic unit used to measure pressure or tension.

Key facts!

• In a new study, researchers tested the fracture resistance of the ultra-tough alloy by exposing it to extremely cold temperatures.
• Their goal was to determine how well the material holds up under stress.
• Scientists observed that this alloy only became tougher and more resistant to cracks as temperatures dropped.
• This discovery came as a result of the team’s investigation into the relationship between temperature and the behaviour of the alloy.
• According to the authors of the study, this very high resistance to fracture stands in stark contrast to the behaviour of most materials.
• The majority of materials when exposed to freezing temperatures only become more brittle.
• Aircraft aluminium alloys are 35 megapascals per metre tough.
• In contrast, this material possesses a hardness that ranges between 450 and 500 megapascals per metre.
• A strong material like this could be used for a lot of different things, like building space infrastructure.
• In addition to making containers that can be used to make clean energy here on Earth.
• However, nickel and cobalt are excessively expensive components.
• So this limits the applicability of the alloy to the laboratory for the foreseeable future.
