The Material Revolution in Bucket Teeth: The Leap from High-Manganese Steel to Composite Materials

As construction machinery evolves toward greater efficiency and intelligence, the materials used for bucket teeth have undergone significant transformation. While traditional high-manganese steel offers high toughness, it suffers severe wear during hard rock operations. In contrast, modern composite bucket teeth, enhanced with tungsten carbide particles, achieve a service life three times longer. Field tests at a mining site demonstrated that bucket teeth coated with vanadium-titanium alloy maintained continuous operation for 800 hours without fracture during iron ore extraction, validating the value of material innovation. Looking ahead, the application of nanocoatings and self-healing materials may emerge as the next trend.
