Cobalt and Nickel are often used together in alloys, especially for their magnetic properties. They're also popular for their strength and corrosion resistance, which can make them suitable for many applications, including turbine blades and aircraft engines.

One of the most common alloys with nickel and cobalt is Alnico, which produces permanent magnets. It's a popular choice for its ability to maintain its magnetic qualities even under high temperatures, making it an ideal material for a variety of devices and equipment.

Other popular alloys with nickel and cobalt include Ni-Fe-Cr, which is a precipitation hardening nickel alloy that offers strength and good workability. It also has excellent corrosion resistance in a wide range of environments, from seawater to acid and alkalies.

Another popular nickel alloy is iron-nickel, which is nonmagnetic but has excellent corrosion resistance in a variety of environments. It's also an excellent choice for high-temperature applications, so it's an ideal material for things like heat exchangers and pumps.

Researchers have proven that a metallic alloy of chromium, cobalt and nickel is the toughest material on Earth -- more than 100 times tougher than graphene.

To test how fracture-resistant the alloy is, scientists exposed it to temperatures of minus 321 degrees Fahrenheit. As the temperature fell, the material's toughness only got progressively better, according to the study. This was especially surprising because most materials become more brittle the higher they get in freezing temperatures.
