Tungsten (W)

Trots att volfram upptäcktes 1779 isolerades inte det förrän 1883.

Ren volfram är en grå och vit metall. Den kan skäras med såg, smidas, snurras, dras och extruderas, men är skör och något svår att hantera. Det oxiderar i luft, tål inte höga temperaturer och har utmärkt korrosionsbeständighet. Naturligt volfram innehåller fem stabila isotoper och tjugoen instabila isotoper är kända.

Volfram och dess legeringar används som glödtrådar i elektriska lampor, elektron- och TV-rör, för metallavdunstning och som elektriska kontaktpunkter för bildistributörer.
