What are the materials used to manufacture excavator buckets？

Excavator is a kind of mechanical equipment specialized in earthwork, which is mainly composed of bucket, power system, hydraulic system, transmission system, manipulation system and walking system. Excavator bucket is one of the core parts of the excavator, which usually consists of three parts: bucket ear, bucket handle and bucket.

The following are the main choices for the manufacturing materials of the digging bucket:
High-strength low-alloy steel: high-strength low-alloy steel has high hardness and strength, good wear resistance and toughness, suitable for use as a digging bucket material. It can withstand greater impact and extrusion pressure, increasing the service life of the bucket.
Rigid wear-resistant alloy: rigid wear-resistant alloy mainly refers to the medium carbon steel or low alloy steel surface spray welding or thermal spraying carbide short rod material. This kind of alloy has very high hardness and wear resistance, can effectively resist the digging bucket in the work of wear and damage, extend the service life of the digging bucket.
Cast iron: cast iron is an inexpensive and easy to process material, widely used in the manufacture of digging bucket. Cast iron has high hardness and strength, can withstand the impact and pressure of the excavator in the work, but relatively poor wear resistance.
Manganese Steel: Manganese steel is a kind of alloy steel material with high manganese element, which has very high hardness, wear resistance and impact toughness. It is suitable for use in the vulnerable parts of the digging bucket, such as the tooth plate, the bottom of the bucket and the bucket waist and other positions. Manganese steel can effectively improve the service life and durability of the digging bucket.
High hardness alloy steel: High hardness alloy steel is a kind of material with extremely high hardness and wear resistance, which is suitable for excavator digging in special working conditions. They are commonly used in parts such as cutter blades, rim teeth and dismantlers of excavator buckets to provide extra strength and durability.
These are the common material choices used in the manufacture of excavator buckets. Different working environments and digging needs require the selection of different materials for the manufacture of buckets to ensure their durability and reliability.
