Description

Tungsten Carbide is an exceptionally hard and wear-resistant inorganic compound, primarily composed of tungsten and carbon atoms. Its extreme hardness, high density, and excellent thermal stability make it a critical material for applications demanding superior durability and performance under severe conditions. This material is essential for manufacturers in the metalworking, mining, oil & gas, and aerospace industries seeking to enhance tool life and operational efficiency.

Application

• Cutting Tools & Inserts: Primary material for lathe tools, milling cutters, and CNC inserts for machining steel, cast iron, and superalloys.
• Mining & Drilling Equipment: Used in drill bits, road planning picks, and wear parts for rock drilling and excavation due to its exceptional abrasion resistance.
• Wear-Resistant Components: Fabricated into nozzles, valve seats, seals, and guides in industries like oil & gas and chemical processing to combat erosion and corrosion.
• Metal Forming Dies: Employed in drawing dies, extrusion dies, and can tooling for wire, rod, and tube production.
• Abrasive & Polishing Media: Utilized in the form of powders or beads for lapping, polishing, and surface finishing of hard materials.
• Armor-Piercing Penetrators: Key component in kinetic energy penetrators for military applications, leveraging its high density.

Quality Control

Our Tungsten Carbide powders and sintered grades are manufactured under strict process controls to ensure batch-to-batch consistency and performance. Quality is verified through a comprehensive suite of tests including particle size distribution (PSD), chemical purity, carbon content, and density measurements. We adhere to relevant industry standards and Certificates of Analysis (COA) detailing lot-specific results are available for all shipments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). As a fine powder, it should be kept away from ignition sources and incompatible materials such as strong oxidizers. For long-term storage, keep the container sealed under an inert atmosphere to prevent surface oxidation.
