This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
Naturally occurring tungsten consists of four stable isotopes (182 W, 183 W, 184 W, and 186 W) and one very long-lived radioisotope, 180 W. Theoretically, all five can decay into isotopes of element 72 by alpha emission, but only 180 W has been observed to do so, with a half-life of (1.8 ± 0.2) × 10 18 years; [36] [37] on average, this yields ...
Ferrotungsten is relatively expensive, with the prices around $31–44 per kilogram of contained tungsten. [4] During World War 2, over 21,000,000 lb of Ferro-tungsten and other ferroalloys were shipped to Russia on lend-lease. [3] The cost was more than $12,000,000. Ferrotungsten comes from rich ore raw materials primarily of wolframite or ...

Even at current levels, gold has still held onto most of its long-term gains, having traded at around $250 per ounce in 1999. But with prices down more than $500 an ounce from its highs during ...
Mallory metal is proprietary name [1] for an alloy of tungsten, with other metallic elements added to improve machining.. Its primary use is as a balance weight which is added to the crankshaft of an automotive engine, where the existing counterweight is not large enough to compensate for the weight of the reciprocating and rotating components attached to the crankshaft's connecting rod journals.
The average recycling value per pound of cans in the U.S. is currently $0.56. ... such as the 32-ounce size, there will be fewer per pound. ... Good resources to gauge current prices include ...
Sodium tungstate is obtained by digestion of tungsten ores, the economically important representatives of which are tungstates, in base. Illustrative is the extraction of sodium tungstate from wolframite: [1] Fe/MnWO 4 + 2 NaOH + 2 H 2 O → Na 2 WO 4 ·2H 2 O + Fe/Mn(OH) 2. Scheelite is treated similarly using sodium carbonate.
