                WD-Co12

                PRODUCT

                Introduction

                WD-Co12 could be considered as an intermediate alloy between WD-Co6 and WD-Co1. It contains a higher fraction of hard, brittle carbides than WD-Co6, and has increased resistance to lowangle erosion, abrasion, and severe sliding wear whilst retaining reasonable impact and cavitation resistance. WD-Co12 is often used self-mated or running against WD-Co6 or WD-Co1. The higher tungsten content provides better high temperature properties compared to WD-Co6, and it can be used at temperature up to 700?C.

                WD-Co12 is typically used for cutting tools that need to withstand abrasion, heat and corrosion. Examples include industrial knives for cutting carpets, plastics, paper and synthetic fibres; and saw tips in the timber industry. It is also used for control plates in the beverage industry, pump vanes, bearing bushes and narrowneck glass mold plungers; and for hardfacing of engine valves, pinch rollers in the metal-processing industries, and rotor blade edges.
