Tungsten | Encyclopedia.com

Tungsten is a relatively inactive metal. It does not combine with oxygen at room temperatures. It does corrode (rust) at temperatures above 400 ° C (700 ° F. It does not react very readily with acids, although it does dissolve in nitric acid or aqua regia. Aqua regia is a mixture of hydrochloric and nitric acids.

Tungsten - Periodic Table of Elements and Chemistry

Tungsten is also used as the filament in halogen tungsten lamps. These lamps use halogens like bromine and iodine to prevent the tungsten filament from degrading and are therefore more energy efficient than standard incandescent light bulbs. High speed steel (which can cut material at higher speeds than carbon steel), contains up to 18% tungsten.
