**Wolfram** (/ˈwʊlfrəm/) an **Tungsten** (/tʌŋstən/) jî ye te zanîn elementeke kîmyewî bi sembola kîmyewî W û nimra atomîk 74.

## Dîrok

Di 1871, Carl Wilhelm Scheele asideke nu peydekir, tungstik asid.

## Etîmolojî

Tungsten di swêdî: tung sten yanî "kevire gîran" te, le belê ew ji di bejin wolfram.

Wolfram jî di gelek zimane awrupa da te gotin.

## Teybetîya Fîzîkî

Wolframe xam î hişk di renge gewra-pola û zu te şîkestin. Di nav elementade germa helandine ya heri zeda a wolframe ya.

Wolfram di elektronike de X-ray, ampul û gelek vedore elektronîkte te amelkirin.
