PMA VERSAlloy®
40-60 Diamond Carbide - Tungsten Alloys 

Rankin PMA VERSAlloy® Diamond Carbide hardfacing rods are a special blend of tungsten carbide sintered with nickel, chromium, and boron powder. Fine particle tungsten combined with PMA VERSAlloy's nickel alloy matrix offers the ultimate in extreme wear protection. PMA VERSAlloy rods have a lower melting point than iron, resulting in no dilution of material and the ultimate in wear protection.

Rankin PMA VERSAlloy® Diamond Carbide trapezoid-shaped rods are easy to use and can be applied using Oxyacetylene, GTAW, and SMAW methods.

Rods are available in 18" lengths, with diameters of 3/32", 1/8", 5/32", 3/16", 1/4", 5/16", and 7/16".

Custom powder conversions and cladding are available upon request.

Available Variations of Diamond Carbide:

F Grade - a VERSAlloy nickel matrix with tungsten carbide pellets and finely powdered cast tungsten carbide to toughen the matrix and improve wear resistance.

V Grade - a VERSAlloy nickel matrix with a blend of crushed sintered tungsten carbide.

VSP Grade - a VERSAlloy nickel matrix with a mixture of crushed sintered tungsten carbide and spherical tungsten carbides.

S Grade - a VERSAlloy nickel matrix with a higher percentage of macrocrystalline tungsten carbide for added wear resistance.
