Steel serves as the foundation of our infrastructure, especially in railroads and roads. Titanium’s exceptional strength-to-weight ratio makes it perfect for aerospace and military uses. The metal palladium helps our environment by cutting down noxious emissions up to 90% in catalytic converters.
This piece gets into the top 10 strongest metals and shows what makes each one special by looking at their unique properties, applications, and strength measurements.
Tungsten
Tungsten stands out as one of the strongest metals on Earth with its remarkable combination of properties. This silvery-white lustrous metal has atomic number 74 and chemical symbol W (from its alternate name Wolfram). Its unique characteristics make it essential in modern industry.
Tungsten properties
The metal holds the highest melting point among all metals at 3,410°C (6,170°F), which gives it extraordinary heat resistance. It has the lowest vapor pressure of any metal and keeps its impressive tensile strength even at extreme temperatures. The metal’s density reaches 19.3 g/cm³, putting it right up there with gold and uranium as one of the densest engineering materials you can find.
Most mineral acids barely affect tungsten, thanks to its excellent corrosion resistance. The metal’s thermal expansion coefficient of 4.5 µm/(m·K) matches that of borosilicate glass and silicon, which makes it perfect for glass-to-metal seals. Pure tungsten can be brittle and tough to work with, so manufacturers often mix it with other metals to improve its workability.
Tungsten applications
The metal plays vital roles across many industries. We used about 61% of global tungsten production to make cemented carbides, which deliver exceptional toughness and hardness for cutting tools, drill bits, and wear parts. Steel and superalloy production takes up another 20%, where tungsten boosts hardness, durability, and corrosion resistance.
