|---|---|
| 16th century | Tungsten is first discovered in the 16th century by tin miners, who find and then recognize the metal as a newly useful and undiscovered asset.[1] |
| 20th century | In the 1930s, new applications arise for tungsten compounds in the oil industry for the hydrotreating of crude oils. In the 1950s, tungsten is added into superalloys to improve performance. In the 1960s, new catalysts are born containing tungsten compounds to treat exhaust gases in the oil industry.[2] |
| 21th century | Currently, most tungsten resources are found in China, South Korea, Bolivia, Great Britain, Russia and Portugal, as well as in California and Colorado. About 80% of world’s supply is controlled by China.[3] |

| Year | Event type | Details | Country/region |
|---|---|---|---|
| 1779 | Irish chemist Peter Woulfe examines a mineral from Sweden and realizes it contains a new type of metal.[3] | ||
| 1781 | "In 1781, Wilhelm Scheele continued the research on this new metal and isolated an acidic white oxide"[3] | ||
| 1783 | "Juan and Fausto Elhuyar get that honor. At the Seminary at Vergara in Spain, they researched this mysterious metal. In 1783 they isolated the metal oxide from wolframite and then, unlike the others, reduced it to tungsten metal by heating it with carbon." | Spain | |
| 1847 | Engineer Robert Oxland is granted a patent to prepare, form, and reduce tungsten to its metallic format.[1] | ||
| 1847 | Tungsten salts are used to make colored cotton and to make clothes used for theatrical and other purposes fireproof.[2] | ||
| 1855 | Attempts are made to create steel made of tungsten.[1][2] | Austria | |
| 1858 | Steels containing tungsten begin to be produced.[1] | ||
| 1895 | American inventor Thomas Edison finds that calcium tungstate is the substance with the best ability to fluoresce when exposed to X-rays.[2] | United States | |
| 1900 | A special mix of steel and tungsten is exhibited at the World Exhibition in Paris.[2] | France | |
| 1904 | The first light bulbs using tungsten are patented.[1] | ||
| 1908 | William D. Coolidge discovers that tungsten is an ideal filament material.[3] |
