Did You Know?

1

Coinage King! The US five-cent coin, often called a 'nickel,' isn't 100% nickel, but it's 25% nickel and 75% copper, giving it that classic silvery look. Many other coins worldwide also contain nickel!

2

Magnetic Marvel! Nickel is one of only four elements that are ferromagnetic at room temperature (along with iron, cobalt, and gadolinium)! This means it can be strongly magnetized and used in magnets.

3

Stainless Superstar! Mix nickel with iron and chromium, and BAM! You get stainless steel, a super-strong, corrosion-resistant material that keeps your kitchen utensils and medical instruments sparkling clean.

4

Earth's Fiery Heart! Scientists believe a massive amount of nickel, along with iron, makes up the Earth's inner and outer core, playing a crucial role in generating our planet's protective magnetic field.
