Top 10 Industrial Applications of Tungsten and Its Alloys | DOMADIA™
Introduction: The Metal That Doesn’t Back Down
When the world needs strength, endurance, and performance under extreme conditions — Tungsten steps in. Known for its highest melting point of all metals (3422°C) and incredible density, tungsten and its alloys are indispensable in modern industries.
At DOMADIA™, we supply high-purity tungsten and tungsten alloys that power innovation — from aerospace engines to cutting-edge medical devices. Let’s dive into the top 10 industrial applications of tungsten and its alloys and see why this “unyielding metal” continues to shape the future of engineering.
Top 10 Industrial Applications of Tungsten and Its Alloys
1. Aerospace & Defense
Tungsten’s unmatched density and strength make it ideal for aircraft counterweights, missile parts, and kinetic energy penetrators. Tungsten alloys like W-Ni-Fe and W-Ni-Cu provide high strength and resistance to high temperatures — essential for jet turbine blades and armor-piercing projectiles.
