About Tungspire
Tungspire
With manufacturing rooted in Zigong — the heart of China's tungsten carbide industrial belt in Sichuan — Tungspire is a wear-parts manufacturer built around one conviction: whoever controls the powder controls the part. We are the world's only full tungsten carbide industry chain group, doing every step from powder to finished precision component. Everything except the mine.
The full industry chain advantage
01
Powder
WC powder and Co/Ni binder blending with in-house grade formulation — the foundation of consistency.
02
Blank
Pressing and vacuum sintering to 100% vacuum-tight blanks with zero internal porosity.
03
Precision Machining
CNC grinding, honing, lapping and polishing to micron-level geometry and world-leading sphericity.
Because no step is outsourced, grade chemistry, sintering curves and finishing tolerances are engineered together. The result: faster lead times, lower cost, and traceability from a single powder batch all the way to your receiving dock.

World-leading ball sphericity
Sealing performance of a valve ball is decided by its roundness. Tungspire's precision lapping process delivers sphericity at the global benchmark level, giving metal-to-metal seals a uniform contact band that resists cutting by sand and extends sucker rod pump run life. Every production lot is verified on roundness instruments before packing.
