China is the top global producer of tungsten carbide, hosting over 300 manufacturers, particularly in Hunan, Jiangxi, and Fujian provinces. Leading factories like Zhuzhou Cemented Carbide Group and Zigong Cemented Carbide Group produce thousands of tons annually. B2B buyers seeking reliable OEM solutions often turn to Rettek for high-quality wear parts, snow plow blades, and VSI crusher tips, combining durability with cost efficiency.
What Is Tungsten Carbide Used For?
Tungsten carbide is a hard, wear-resistant material widely used in cutting tools, mining inserts, and industrial wear parts. It withstands extreme abrasion and high temperatures, extending equipment life in demanding conditions.
The material, a composite of tungsten and carbon, is harder than steel while offering superior toughness. Factories like Rettek focus on OEM production for snow plows, VSI rotor tips, and HPGR studs, using cobalt grades from 6-12% to balance hardness and durability. Key applications include:
-
Mining and construction tools
-
Industrial blades and inserts
-
Automotive and aerospace components
Rettek’s integration from raw alloy preparation to automated welding ensures consistent OEM-grade quality for global clients.
Why Choose Chinese Tungsten Carbide Manufacturers?
Chinese manufacturers provide cost-effective, high-volume tungsten carbide, thanks to local tungsten mines and comprehensive industrial chains. They deliver OEM customization, stable quality, and rapid production.
China produces over 80% of the world’s tungsten, enabling factories to control costs from ore to finished parts. Top producers deliver over 8,000 tons annually. B2B buyers benefit from ISO-certified quality controls and traceable processes.
Rettek, based in Zigong, exemplifies these advantages through in-house sintering and brazing, reducing downtime by 30-50% versus competitors. Direct factory orders remove middlemen, offering competitive pricing for bulk OEM purchases.
