Fun Facts
Surprising truths about the metals that shape our world.
Platinum is Denser Than Gold
A cubic foot of platinum weighs about 1,339 pounds — roughly 11% heavier than the same volume of gold. It's the densest commonly traded metal.
Lithium Floats on Water
With a density of just 0.53 g/cm³, lithium is the lightest metal and one of only three metals that float on water (along with sodium and potassium).
Molybdenum Won't Melt Easily
Molybdenum has a melting point of 2,623°C — hot enough that it's used in furnace parts and rocket nozzles where other metals would simply melt.
Tin Melts in Your Kitchen
Tin has one of the lowest melting points of any common metal at just 232°C. A standard kitchen oven could theoretically melt it.
Rhodium is Rarer Than Diamonds
With just 0.001 parts per million in Earth's crust, rhodium is one of the rarest elements. Annual global production is only about 30 tonnes.
Aluminum Was Once More Precious Than Gold
Before the Hall-Héroult process was invented in 1886, aluminum was so expensive that Napoleon III served state dinners on aluminum plates to impress guests.
Cobalt Powers the EV Revolution
About 70% of the world's cobalt comes from the Democratic Republic of Congo. It's essential for lithium-ion batteries in electric vehicles and smartphones.
Iron Makes Up a Third of Earth
Iron is the most abundant element on Earth by mass, making up about 32% of the entire planet. Most of it is in the core, not the crust.
Uranium is Surprisingly Common
At 2.7 ppm in Earth's crust, uranium is more abundant than tin, silver, or mercury. It's about as common as tin and 40× more common than silver.
Palladium Goes in Your Exhaust
Over 80% of palladium produced goes into catalytic converters. A single converter contains 2-7 grams of palladium, platinum, or rhodium.
