The Bucket teeth of excavators, as the core wear-prone components directly in contact with ore, rock, and soil in construction machinery, are known as the "blades" of excavator operations. They are widely used in various construction scenarios such as open-pit mining, infrastructure excavation, tunnel engineering, sand and gravel extraction, river dredging, and construction waste processing. In 2026, domestic infrastructure investment will steadily materialize, the renewal cycle of mining equipment will arrive in a concentrated manner, and overseas exports of construction machinery will continue to expand. Coupled with breakthroughs in wear-resistant material technology and the upgrading of environmental protection policies, the bucket teeth industry will usher in a window of structural transformation, with comprehensive upgrades in market demand, production processes, and product standards.

From the overall market demand perspective, the industry scale has maintained stable growth. Industry research data shows that the domestic tooth plate market continues to expand, with an average annual compound growth rate of around 7%. Among these, the market for ordinary cast tooth plates has reached saturation, where homogenized low-price competition compresses profit margins. In contrast, high-end products such as mine-specific high-wear-resistant tooth plates, composite alloy tooth plates, lightweight precision cutting edges, and smart monitoring tooth plates have grown far faster than the industry average, with their market share increasing year by year. In heavy-duty applications like open-pit mines and hard rock quarries, customers no longer simply compare unit procurement prices but place greater emphasis on the comprehensive service life, replacement frequency, and downtime losses of tooth plates. The total cost per operating hour has become the core criterion for procurement decisions.

The materials and heat treatment technologies have achieved leapfrog upgrades, addressing the industry pain points of traditional bucket teeth—being "wear-resistant but prone to breakage, and impact-resistant but not wear-resistant." The current industry has established three mainstream material systems: high-manganese steel, multi-component low-alloy steel, and tungsten carbide composite wear-resistant materials. High-manganese steel boasts strong matrix toughness, making it suitable for light-duty excavation scenarios involving soil and gravel. Chrome-molybdenum-vanadium multi-component alloy steel, through precise isothermal quenching, achieves a gradient hardness with an outer-hard and inner-tough tooth tip, reaching HRC58-62 hardness, and exhibits over 35% higher impact resistance and wear resistance compared to ordinary cast steel. Laser cladding of tungsten carbide and hard alloy surfacing techniques are gradually becoming widespread, extending bucket tooth service life by 2-3 times in ultra-hard rock mining conditions. Meanwhile, CAE simulation technology has been fully implemented, optimizing tooth profile curvature and pin-hole structures through simulations of excavation impacts and material friction forces during the R&D phase, thereby reducing breakage and detachment failures during operation.

The manufacturing sector is comprehensively transforming toward precision, green, and intelligent upgrades. Traditional sand casting is gradually being replaced by lost foam casting, silica sol investment precision casting, and multi-directional die forging processes, effectively reducing defects such as porosity, shrinkage, and dimensional deviations. The fit clearance between bucket teeth and tooth seats is controlled within an extremely tight tolerance range, significantly minimizing pin and sleeve wear. Fully automated continuous heat treatment production lines, CNC shot blasting, coordinate measuring machine full inspection, and salt spray wear resistance testing equipment have become standardized supporting facilities, achieving end-to-end quality control from raw material storage to finished product delivery. On the environmental front, high-pollution outdated foundry capacities continue to be phased out, while low-energy heat treatment, scrap steel recycling, and dust-free grinding production lines are widely adopted, aligning with green manufacturing policy requirements.

Intelligent operation and maintenance has become a new development track, and intelligent bucket teeth with built-in sensing chips have entered the industrial application stage. This type of product can collect real-time data on the degree of wear and impact stress during operation, and synchronize it to the cab terminal through wireless transmission. It can provide early warning of severe wear and loss of teeth, prevent tooth loss from entering the crushing equipment and causing significant equipment damage, and effectively reduce downtime losses in mines and construction sites. Industry insiders predict that the penetration rate of the intelligent wear-resistant bucket teeth market will continue to rapidly increase in the next two years, becoming a new growth pole in the industry.

The export market ushered in continuous expansion. With the implementation of infrastructure projects and overseas mineral development projects along the "the Belt and Road", domestic bucket teeth were exported to Southeast Asia, Central Asia, Africa, Latin America and other regions by virtue of stable quality, rich model coverage, and cost-effective advantages. The industry is synchronously improving its international certification system for ISO wear resistance and environmental management, adapting to the matching needs of different working conditions and models overseas. The proportion of high-end wear-resistant bucket teeth orders overseas continues to increase.

Industry analysts say that the future development of the bucket tooth industry will revolve around four core directions: first, continuous research and development of special alloy wear-resistant materials to adapt to extreme high and low temperature, high corrosion mining environments; Secondly, the popularization of precision forging and composite strengthening processes comprehensively improves the overall service life of products; The third is the large-scale implementation of intelligent monitoring and predictive operation and maintenance components; The fourth is the green and low-carbon full process production transformation. With the continuous promotion of localization of construction machinery and intelligent construction of large-scale mines, the wear-resistant parts industry chain, which combines material research and development, precision machining, and complete testing capabilities, will continue to grasp the dividends of industry upgrading.
