Description

Ferrotungsten is a critical ferroalloy composed primarily of iron and tungsten, essential for imparting high-temperature strength, wear resistance, and hardness to steel and other alloys. Its primary value lies in its efficiency as a master alloy for introducing tungsten into molten metal, ensuring precise composition control and superior metallurgical properties. This product is indispensable for manufacturers in the tool steel, high-speed steel, armor plating, and wear-resistant alloy industries, where material performance under extreme conditions is paramount.

Application

• High-Speed and Tool Steel Production: A key additive for manufacturing cutting tools, drills, and dies that require exceptional hardness and red-hardness (ability to retain hardness at high temperatures).
• Wear-Resistant Alloys & Hardfacing: Used in surfacing applications and castings for mining equipment, crusher parts, and machinery components subject to severe abrasion.
• Armor and Military Alloys: Employed in the production of heavy-duty armor plating and penetrators due to its high density and strength.
• Maraging Steels and Superalloys: An important alloying element in high-strength, low-carbon steels and nickel-based superalloys used in aerospace and turbine components.
• Foundry and Metallurgy: Serves as a reliable tungsten source for precise alloying in foundry operations and secondary steelmaking processes like ladle furnace treatment.
• Electrical Contacts and Heavy Metal Alloys: Used in alloys for electrical contacts and high-density counterweights or balances.

Quality Control

Our Ferrotungsten is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and compliance with international standards such as ISO and ASTM. Key parameters including tungsten content, particle size distribution, and impurity levels are rigorously verified. A Certificate of Analysis (COA) detailing all specification results is provided with every shipment to guarantee traceability and quality assurance for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from incompatible materials. The product is stable under normal storage conditions but should be kept dry to prevent surface oxidation. Maintain ambient temperature (15-25°C).
