Crusher liners are made from various materials, commonly including manganese steel, chrome iron, and cast iron. The choice of material typically depends on the type of crusher and the characteristics of the material being processed.

Manganese Steel
Manganese steel is one of the most commonly used materials for crusher liners. It has the ability to harden upon impact, enhancing its wear resistance. Manganese alloys typically also contain certain amounts of carbon and chromium. Manganese steel of MNX50 grade offers excellent performance, especially for primary crushing equipment. In terms of service life, the average lifespan of a Mn13 liner is about 45 days, while Mn18 liners last approximately 60 days. Due to its work-hardening properties, manganese steel has become the material of choice for crusher wear parts. When in contact with rocks, the surface of manganese steel hardens gradually, making it more wear-resistant than other alloy materials. Manganese crusher liners can withstand significant impact, thus extending the service life of the crusher.
Cast Iron
Ni-hard cast iron is a special material alloyed with nickel and chromium, commonly used for liners in jaw crushers. This material has excellent wear resistance, making it particularly suitable for processing materials with high hardness.
Other Materials
Other alloy materials, such as B9 alloy steel, martensitic steel, martensitic ceramic matrix, and chrome ceramic matrix, can also be used in the manufacture of crusher liners. The choice of liner material is closely related to the nature of the processed material, particularly its hardness and sliding characteristics. Proper selection of the liner material can significantly improve the crusher's working efficiency and effectively extend the equipment's service life.
