What is the material of the excavator bucket teeth

In the field of engineering machinery, excavator bucket teeth are key components in the excavator working device that directly contacts materials, and their material selection directly affects service life and operating efficiency. This article will combine the popular topics and hot contents of the entire network for the past 10 days to deeply analyze the material composition, performance characteristics and industry trends of the excavator bucket teeth.

1. Core material of excavator bucket teeth

What is the material of the excavator bucket teeth

Excavator bucket teeth are usually made of high wear-resistant alloy steel material and are made by casting or forging processes. Here is a comparison of mainstream materials:

Material TypeIngredient characteristicsHardness (HRC)Wear resistanceApplicable working conditions
High manganese steelMn content 11%-14%18-22Hardening after impactMedium hard rock strata
Low alloy steelCr, Mo, B elements45-52Stable and wear-resistantSand and gravel earth
Composite ceramicsTungsten Carbide Particles60+ExcellentMining

2. Recent industry hot technologies

1.Nanocoating technology: The "surface plasma spraying" technology hotly discussed in a mechanical forum can extend the life of the bucket teeth by 30%.

2.3D printing of bucket teeth: European manufacturers launch customized trowel solutions to achieve integrated molding of complex structures

3.Intelligent wear monitoring: A newly released IoT bucket teeth of a domestic brand are equipped with RFID chips to transmit wear data in real time

3. Analysis of material selection trends

According to recent e-commerce platform sales data (statistics in August 2023):

Material Typemarket sharePrice range (yuan/piece)Repurchase cycle
Traditional high manganese steel45%80-1503-6 months
alloy steel38%200-3508-12 months
Composite materials17%500+More than 1.5 years

4. Five issues that users care about the most

1. How to identify the authenticity of the bucket tooth material through sparks?
2. The best choice of bucket teeth material for different soil quality
3. Effect of welding repair on material properties
4. Comparison of cost-effectiveness between imported brands and domestic materials
5. Guarantee of material toughness in extreme low temperature environments

5. Maintenance suggestions

1. Check the cracks at the root of the bucket teeth regularly (it is recommended to work every 50 hours)
2. Avoid material fatigue caused by long-term overload operations
3. Use suitable tooth seats and fixed pins for matching
4. It is not recommended to mix the bucket teeth of different materials.

With the development of materials science, excavator bucket teeth are evolving from single wear resistance to "wear resistance-impact resistance-lightweight" comprehensive performance. A recent paper published by a university shows that the life of experimental bucket teeth with rare earth elements increases by 40% under basalt conditions, which may become the research and development direction of the next generation bucket teeth materials.
