Manufacturing Process

The manufacturing process of Tungsten Carbide and Tungsten showcases the stark differences between these two materials. Despite their shared element, Tungsten, their production journeys are unique. Dive into the intricate world of how these incredibly tough substances come to life within the industrial landscape.

Tungsten Carbide Production

Tungsten Carbide, known for its exceptional hardness, begins as tungsten ore. Through a series of crushing, milling, and purifying, the ore transforms into Tungsten Oxide (WO3). Carburization comes next; this is when carbon is added at high temperatures. The result? A fine powder that is the precursor to Tungsten Carbide.

The magic happens in a high-pressure furnace. Here, the powder is pressed into molds. These become the blanks for various tools and parts. Next comes sintering. This involves heating the blanks to a point where they bond without reaching a melt. Sintering is the key that unlocks the toughness and durability of Tungsten Carbide.

Shaping and finishing the sintered parts give them the final touch. Precision ensures each piece meets exacting specifications. The production of Tungsten Carbide culminates in robust components set for challenging environments.

Tungsten Production

The journey of pure Tungsten production is less complex but equally fascinating. It starts with the same Tungsten Oxide derived from ore. Unlike Tungsten Carbide, production here heads toward reduction.

Tungsten Oxide encounters hydrogen or carbon at high temperatures. This reduction process strip away the oxygen. What remains is pure Tungsten powder.

The powder then goes through pressing and sintering, similar to Tungsten Carbide. However, the desired result differs. With Tungsten, manufacturers aim for a dense, metal form. This forms the basis for filaments in lighting or electrical contacts.

Final steps for Tungsten involve re-heating and forming it into rods or wires. These are then drawn into the fine wires or shapes needed for their end use. The result is a metal ready to take on heat and electricity with impressive resilience.
