description Product Description
Used as a filament in incandescent light bulbs due to its high melting point and durability.
Commonly alloyed with steel to produce high-speed tool steels for cutting and drilling equipment.
Employed in aerospace and defense industries for heavy alloys in counterweights, radiation shielding, and armor-piercing projectiles.
Serves as a critical component in electronics, including semiconductors and circuit board components.
Utilized in high-temperature applications such as furnace heating elements and welding electrodes.
Acts as a catalyst in certain industrial chemical reactions, especially in petroleum refining.
