Impactor crusher spares - the genuine alternative
Manganese steel wear parts
GN BRAND Casting manganese wear parts are a relatively lowcost option, offering good wear life and are ideally
suited for high impact applications where tramp metal or uncrushable objects are included in the feed material.
Available in standard & premium grade manganese steel.
Martensitic steel wear parts
GN BRAND Casting martensitic wear parts are considered ideal in applications where the feed material varies.
Offering impact resistance similar to Manganese Steel with improved wear properties, they also demonstrate good
resistance to abrasive gouging.
Chrome white iron wear parts
GN BRAND Casting chrome white iron wear parts are ideally suited to applications with high abrasion offering cost
effective wear life. They are not suited to applications where tramp metal or uncrushable objects are included in the
feed material. Available in medium & high chrome grades.
