A heavy grey-white metallic element; the pure form is used mainly in electrical applications; it is found in several ores including wolframite and scheelite.

2 At present, I am immensely occupied, engaged in collecting wolfram .
3 We have not examined barium, wolfram , or uranium.
4 Oil, rubies, trams, wolfram , rubber, and so on.
5 The following analysis will illustrate the composition of a sample of Cornish wolfram as brought into the market:-
6 Ingots of wolfram and Glantz steel.
7 Do you know what wolfram is?
8 Subtract (1) from (3) to get the weight of wolfram taken:
9 Iron, copper, and arsenical pyrites, antimony, galena, molybdenite, zinc blende, and wolfram were treated in the above manner with similar results.
10 This chemical is a salt, made by roasting wolfram with soda ash, and wolfram is a native tungstate of iron and manganese.
11 In many places I saw mounds the marmots had made from copper ore and farther north some from minerals containing wolfram and vanadium.
12 They have agents all over the country, who pull strings in wolfram and the ruby mines, and have a finger in every mortal thing.
13 In turn, the city could throw up enough low-grade molybdenum and wolfram as a byproduct of drilling to satisfy the terms of the Proctors.
14 And in this case, Wolfram Alpha gets its results from Best Buy.
