    Colmonoy and Wallex Surfacing Alloys:

    Wear-resistant Hard-Surfacing Alloys to Maximize Performance and Extend Useful Life

    For over 80 years, Wall Colmonoy has been the global leader in the manufacture and application of surfacing products. Wall Colmonoy’s standard and custom range of Colmonoy® and Wallex™ surfacing alloys have outstanding metallurgical and physical properties making them ideally suited to solving engineering problems such as Wear, Corrosion, Erosion and Abrasion.

    Our specially formulated COLMONOY® and WALLEX™ surfacing alloys extend the useful life of engineered components for such global industries as Oil & Gas, Glass Container, Rubber & Plastics, Power Generation, and Steel.

    Parts protected last significantly longer:

    • Fewer Replacement Parts
    • Minimize Downtime
    • Reduce Operational Expense

    Our alloys are available as powder, rods and wire in a full range of sizes and specifications.  Powders can be Gas or Water atomized and produced to specific alloy formulations. Supplied in a range of proven surfacing and thermal spraying techniques including Laser Cladding, PTA, HVOF, Spray & Fuse and other spray and powder applied processes.
