Tungsten, Grade Information
Tungsten
Tungsten carbide inserts, end mills, wire, and alloy items, priced per kilogram. The densest and hardest commercially used metal, and now one of the most strategically valuable.

History & Interesting Facts
Tungsten was first identified as a distinct element in 1781 by Swedish chemist Carl Wilhelm Scheele, who isolated tungstic acid from the mineral scheelite. The name "tungsten" comes from the Swedish "tung sten" meaning "heavy stone," while its chemical symbol W derives from the German name Wolfram, used by the German mineralogists who independently described it. For much of the 19th century, tungsten remained a laboratory curiosity. Its practical era began in 1904 when William Coolidge at General Electric developed a method for drawing tungsten into ductile wire, enabling the first long-lasting incandescent light bulb filaments. During both World Wars, tungsten carbide's extraordinary hardness made it strategically vital for armour-piercing shells and machining tools; tungsten-producing nations wielded enormous geopolitical leverage. Today, with China controlling over 80% of global production and implementing strict export controls in January 2026, that strategic importance has returned.
Historical Uses
Tungsten's first major industrial application was in electric light bulb filaments, where its uniquely high melting point of 3,422°C allowed it to glow brilliantly without melting. This single application drove the entire early tungsten industry. In WWI and WWII, tungsten carbide, an extraordinarily hard compound of tungsten and carbon, proved decisive in machining: factories equipped with tungsten carbide-tipped cutting tools could machine steel ten times faster than with high-speed steel, giving Allied nations a crucial manufacturing advantage. Tungsten alloys (often called "heavy alloys," containing 90–97% tungsten with nickel and iron) replaced lead in armour-piercing projectiles. Tungsten electrodes became universal in TIG welding. Tungsten wire remained the standard for incandescent bulb filaments globally through to their phaseout in the 2010s. Tungsten disulphide lubricants performed in environments where conventional oils would fail, from spacecraft components to Formula 1 gearboxes.
Current Uses
Tungsten carbide today accounts for approximately 60% of all tungsten consumption globally, used in cutting tools, lathe inserts, milling cutters, drill bits, end mills, and wear parts. CNC machining centres across UK manufacturing use tungsten carbide inserts at enormous rates; worn inserts accumulate at every engineering workshop. Mining and tunnelling equipment uses tungsten carbide buttons and picks for rock drilling. Wire drawing dies for producing copper and steel wire are almost universally tungsten carbide. Wear-resistant components in pumps, valves, and flow control equipment use tungsten carbide for its unmatched resistance to abrasion. Tungsten heavy alloys (W-Ni-Fe) are used for radiation shielding in medical imaging equipment and nuclear facilities, and as ballast weights in aircraft, racing cars, and sailboat keels. Tungsten wire is still used in specialised high-temperature heating elements.
Future Possible Uses
Tungsten's strategic importance is accelerating due to geopolitical supply concentration and surging demand from advanced manufacturing. China's export controls implemented in January 2026 have triggered urgent efforts by Western nations to establish alternative tungsten supply chains, including recycling programmes that treat urban scrap as a critical strategic reserve. The development of tungsten-rhenium alloys for hypersonic missile and aerospace applications represents a growing defence-driven demand. Tungsten carbide is being explored in quantum computing hardware components requiring extreme dimensional stability. The global push for precision manufacturing in semiconductors and medical devices ensures continued growth in tungsten carbide tooling demand. Tungsten recycling, of which the UK scrap market is a key part, will become progressively more strategically and economically important as primary supply tightens.
Where Does This Scrap Come From?
Tungsten scrap at QuickStop comes in several forms. Tungsten carbide inserts (the small indexable cutting tips used in CNC lathes and milling machines) are the highest-value form, engineering workshops, toolrooms, and precision machining companies accumulate worn inserts continuously. Solid carbide end mills, drills, and reamers that have been reground to their minimum usable diameter are another premium source. Tungsten carbide wear parts from pumps, dies, and valves arise from industrial maintenance. Tungsten wire from specialist heating elements and vacuum furnaces provides pure tungsten. Tungsten heavy alloy items, radiation shielding bricks, diving weights, gyroscope components, and ballast weights, provide dense, high-value material. The easiest identification test: tungsten carbide is dramatically heavier than steel for its size (density ~14.9 g/cm³, nearly twice that of steel), and a hardness test (it will scratch steel but won't be scratched by it) confirms the grade.
How Is It Remanufactured?
Tungsten scrap recycling is a sophisticated, high-value process. Clean carbide inserts and solid carbide are first sorted, cleaned, and crushed. The crushed material undergoes a chemical conversion, either the zinc reclaim process (where zinc is alloyed with the tungsten carbide at ~900°C then vacuum-distilled off, leaving reclaimed tungsten carbide powder) or a full chemical conversion to ammonium paratungstate (APT) via acid leaching, solvent extraction, and precipitation. APT is then calcined to tungsten oxide and reduced with hydrogen to produce tungsten metal powder, which is carburised with carbon to produce new tungsten carbide powder. This powder is mixed with cobalt binder, pressed, and sintered to produce new carbide blanks. The full cycle recovers virtually 100% of the tungsten value. Given virgin tungsten prices above £40–55/kg following China's export controls, the economics of recycling are exceptionally strong.
5-Year Price Trend & Forecast
Tungsten has experienced one of the most dramatic price surges of any scrap metal in recent years. In early 2024, tungsten carbide powder traded at approximately £25–30/kg. Through 2025, China's progressive tightening of export controls, including a licensing phase implemented in February 2025 that cut tungsten oxide exports by nearly 70%, drove prices sharply higher. By January 2026, tungsten carbide powder had reached approximately £55–70/kg following China's activation of strict dual-use export controls. UK scrap yard prices for clean carbide inserts have tracked this move, rising from approximately £15–20/kg in 2023 to £30–50/kg for top-grade clean solid carbide in early 2026. Analysts forecast sustained high pricing through 2026–2027 as new Western mine supply remains years away.
