Cobalt-Base Alloys—Wall Colmonoy

TABLE 5.9 COBALT-BASE ALLOYS-WALL COLMONOY 

The name Wallex designates a line of cobalt-base hard-surfacing alloys. All of them resist corrosion well, but they vary in their ability to resist abrasion and impact, and in the way they can be applied. Wallex alloys would seldom be recommended for protection against corrosion alone. In most cases, they are chosen for their ability to fight the twin hazards of corrosion and abrasion. The specific alloy choice depends on a careful analysis of the extent of the problem presented by each hazard.
