Comprehensive range of Advanced Metals and Materials designed to enhance product lifecycle and reduce maintenance costs

1. Raw Material Extraction
Tungsten is primarily extracted from wolframite and scheelite ores, found mainly in China, Russia, and Bolivia. The mining process involves crushing and grinding the ore to release tungsten minerals, followed by separation and concentration to increase purity.

2. Refining and Smelting
The concentrated tungsten ore undergoes roasting to produce tungsten oxide (WO₃). This oxide is then reduced in a furnace, typically with hydrogen or carbon, to produce metallic tungsten. Further refining ensures high purity, suitable for industrial applications.

3. Tungsten Products
Refined tungsten is used in:

Alloys: Combined with steel to make high-speed tools, cutting tools, and drill bits due to its hardness and high melting point.
Electronics: In lightbulb filaments and electronics contacts.
Aerospace: For parts exposed to high temperatures and extreme stress.
Tungsten’s exceptional hardness, high melting point, and density make it essential for industries requiring durable, heat-resistant materials.

Introduction Tungsten is the refractory metal with the highest melting point, known for its high density and low thermal expansion coefficient. It maintains exceptional strength and good electrical resistivity even at extremely high temperatures. However, pure tungsten is very difficult to process and manufacture. Eagle Alloys offers finished tungsten parts with quick turnaround times and provides various tungsten alloys, including lanthanum-tungsten (1%, 1.5%, 2%) and thorium-tungsten and tungsten-rhenium (1%, 2%, 3%, 4%) alloys.
