Alloy teeth for roller cone drill bits
The SY13/SY15 grades are manufactured using premium-grade tungsten carbide raw materials and a unique formulation structure, ensuring that the products not only deliver exceptional wear resistance but also exhibit outstanding impact resistance, bending strength, and thermal fatigue performance. This product line is widely used across China, Iran, Russia, Canada, South America, Latin America, and other regions—and has earned an excellent reputation, particularly in West Asian and Middle Eastern countries like Saudi Arabia, helping customers achieve significant economic benefits and strong brand recognition.
SY10/SY11: Our company has specifically developed this grade as a product tailored for rotary drilling and trenchless engineering projects. Its key features include a unique grain structure, which significantly enhances the material’s toughness and wear resistance. As a result, it outperforms traditional grades in terms of operational stability and service life.
