I don't know anyone who refers to the element as wolfram in English. The abbreviations are internationally standardized and many don't stand for the English words anyway (Latin is quite common, e.g. Pb means plumbum, for lead).

I also don't know anyone who refers to it as wolfram, but wolfram is all over the tungsten wikipedia page.

The symbol is W, which stands for Wolfram. So everyone refers to it that way, at least initially.

That's gonna be people either in specialized areas, or non-native English speakers using their own words. I see British English spelling all over Wikipedia, for example, but I never see anyone in my actual life in the US use it except for one guy who is from, you can guess.
