Let’s embark on a journey through the historical hallways of scientific discovery to uncover the fascinating journey of tungsten metal, admired over recent centuries for its amazing qualities and practical applications. The discovery and history of tungsten reflect an intriguing story that spans millennia, highlighting its transformation from a freshly discovered element to a vital substance in modern industry. This investigation digs into the deep elements of tungsten’s past, tracing its origins back to the Middle Ages through to the 18th-century analysis by the Spanish Elhuyar brothers which represented a watershed moment in chemistry and metallurgy and ignited the modern era of tungsten metal’s use and value.
Tungsten wasn’t always considered a valuable mineral and known for its useful properties. Some of our earliest accounts of tungsten date back to a period where it was seen as a burdensome element because of its negative effect on tin yields while its heat resistance, durability and strength were not yet well understood. During the Middle Ages, 16th-century miners in Germany’s Saxony-Bohemian Erzgebirge region recognised this problematic mineral that was typically encountered alongside tin ore. This material presented problems during smelting, lowering tin production. A layer of foam formed on the surface of the tin, and a dense deposit formed in the smelting stove, retaining the valuable tin. Miners described it as pulling the tin away, like a wolf devouring a sheep. They called it “wolffram” because of this and its dark colour and hairy appearance. This vexing mineral was originally mentioned by Georgius Agricola in his 1546 book “De Natura Fossilium.”
The term “tungsten” was derived from another important tungsten mineral, now known as scheelite. This heavy mineral was discovered in 1750 at Sweden’s Bispberg iron mine. Because of its high density, Axel Frederik Cronstedt named it Tungsten (composed of the Swedish words tung, meaning heavy, and sten, meaning stone) in 1757.
Carl Wilhelm Scheele, a Swedish scientist, presented the results of his research on tungsten metal in 1781, indicating that it contained lime and a new acid aptly called tungstic acid. It was suggested that tungsten metal could be produced by reducing the acid with charcoal. Fausto and Juan Jose Elhuyar, Spanish brothers in the scientific field, emerged as trailblazers shortly thereafter. The two, who come from a family of prominent chemists, set out on a journey to discover the mysteries of minerals found in Spain’s mineral-rich regions. Their efforts paid off in 1783 when they separated a new element from the mineral wolframite. This historic finding gave birth to tungsten, a term drawn from the ore itself, and dubbed the newly discovered element “wolfram.” The laborious effort of Fausto and Juan Jose de Elhuyar in isolating tungsten was a credit to their scientific skill and perseverance. Their discovery not only contributed a new element to the periodic table, but it also established the groundwork for understanding the special features of tungsten. Tungsten metal’s unique properties, such as its high melting point and density, intrigued scientists worldwide, sparking a wave of exploration into potential applications for this newfound element.
Tungsten Metal’s Early Applications:
As the nineteenth century began, the promise of tungsten metal began to appear in practical applications. The Elhuyar brothers’ discovery opened up a world of possibilities, and tungsten found its first industrial application in the production of incandescent light bulbs. Because of the metal’s capacity to sustain high temperatures without melting, it was a perfect candidate for filament manufacturing, revolutionising the world of lighting. Tungsten’s brilliance exposed not only spaces but also the scientific community to its potential significance.
During the Industrial Revolution, the characteristics of tungsten were further investigated, leading to its use in cutting-edge technology. Tungsten metal became a pillar in the creation of cutting tools and drills in the late nineteenth century, changing machining operations with its outstanding hardness and durability. This marked the beginning of tungsten metal’s crucial role in improving efficiency and precision across a wide range of sectors, laying the groundwork for its evolution into a modern technology cornerstone.
Tungsten-containing steels were patented in 1858, paving the way for the first self-hardening steels in 1868. At the 1900 World Exhibition in Paris, high-speed steels with tungsten additives were displayed, revolutionising engineering practice. Many of these steels are still utilised in machine shops around the world.
Modern Tungsten Applications:
Tungsten’s historical trajectory, which began with the visionary efforts of Fausto and Juan Jose de Elhuyar, has continued into the modern period when it has become a vital component in a variety of industries. An important application is the manufacturing of superalloys, which are essential in the aerospace and defence industries. Interested in learning more from a modern tungsten metal producer?

The study of tungsten’s journey goes deeper into the electronics industry, where its use in semiconductors and integrated circuits and further emphasises its importance. With its high heat conductivity and corrosion resistance, tungsten aids the dependability and efficiency of electronic gadgets that have grown ubiquitous in modern life. Furthermore, tungsten has found a position in medical technology, helping to manufacture radiation shielding for medical X-ray devices. This application protects both patients’ and healthcare professionals’ safety. Tungsten metal alloys are also employed in the manufacturing of medical implants, leveraging their biocompatibility and strength. In the field of renewable energy, tungsten is essential in the manufacture of photovoltaic cells for solar panels. Tungsten’s durability and stability contribute to the endurance and efficiency of solar energy systems, connecting it with the imperatives of long-term energy solutions.
The list of modern applications for tungsten metal is seemingly endless which is why this element is so highly sought after in the modern landscape and deemed a critical mineral by the world’s leading nations.
The discovery and history of tungsten metal reflect an intriguing story that spans half a millennia, highlighting its transformation from a freshly discovered element to a vital substance in modern industry. Reflecting on the history of tungsten reveals a story of scientific curiosity, industrial ingenuity, and a metal that continues to affect the technological landscape of the twenty-first century. The pioneering work of Fausto and Juan Jose de Elhuyar serves as a beacon in this story, guiding us along the hallways of discovery that have led to the remarkable prominence of tungsten in our modern world.
