Duablock® is a composite material used in mining applications experiencing severe wear. This product consists of a white iron casting bonded to a backing plate. Duablock®’s wear resistant microstructure, along with its impact absorbing backing plate, makes it perfect for high abrasion and high impact applications.
The microstructure of Duablock® is crucial in providing superior wear performance. The heat treatment cycle transforms the softer as-cast microstructure into hard, wear-resistant material. This microstructure consists of a network of interconnected eutectic M7 C 3 carbides in a martensitic matrix.
