ስለ Tungsten

Tungsten has the highest melting point (3,695 K), highest tensile strength, and lowest vapor pressure of any pure metal. It is extremely dense and hard.

ፕሮግራሞች

Light bulb filaments, cutting tools (tungsten carbide), armor-piercing projectiles, X-ray tubes, and heating elements.

ሐቅ

Tungsten has the highest melting point of any element at 3,695 K and was chosen for incandescent bulbs because it can glow white-hot.
