Duaplate® DX

Overview

Duaplate® DX offers a unique and superior weld overlay product that outperforms conventional Chromium Carbide Overlays (CCO). Bradken has employed the latest digital technology in order to create an overlay with a patented chemical composition that is incredibly resistant to high impacts and severe abrasive environments. The phenomenal properties of Duaplate® DX are matched only by its versatility. Available in large sheet sizes and custom shapes, Duaplate® DX can be cut and formed to suit customer requirements.

Duaplate® DX is a special blend of carbides and borides in a highly refined overlay product. Its engineered micro structure increases hardness, toughness and abrasion resistance over conventional chromium carbide overlays.
Manufacture
Duaplate® DX is manufactured by fusing Bradken’s specially formulated powder to a mild steel base plate. This creates a bi-metallic material with superior abrasion resistance, which is also highly ductile in order to accommodate forming and welding.
Microstructure
The unique microstructure of Duaplate® DX consists of a mixture of extremely fine carbides and borides that are surrounded by a predominantly martensitic matrix material. These incredibly hard carbides and borides are approximately 10x smaller than traditional carbides in CCOs, which dramatically increases resistance to wear and further improves impact performance.
Typical Properties
Mine site trials have confirmed that Duaplate DX has achieved 2-3 times increase in wear life over standard CCO plates and has demonstrated noticeable increase in impact resistance. The reduced liner weight of Bradken’s Duaplate® DX also outperforms other products in relation to manual handling and safety.
