POLYTUNG NIBWC

Characteristics and Composition

POLYTUNG NiBWC is a high quality tungsten carbide metal cored wire ideal for protecting your equipment in the harshest environments. When welded this material has excellent fine particle erosion and corrosion resistance. POLYTUNG NiBWC will increase the life of your parts, reducing downtime and increasing productivity.

Applications for POLYTUNG NiBWC include: drill bits and stabilizers, dredge cutter teeth & heads, mud pumps, and other applications in a variety of industries.

POLYTUNG is a nickel silicon boron matrix system with WC particles. This combination produces a superior microstructure when welded.

POLYTUNG NICRBWC

Characteristics and Composition

POLYTUNG NiCrBWC is a nickel chrome boron silicon matrix system, with 38-44% tungsten carbide particles. This combination produces a superior micro-structure when welded and has excellent fine particle erosion, corrosion and toughness. The low heat input when welding POLYTUNG NiCrBWC reduces the amount of tungsten carbide particles going into solution. Deposits are not machinable and can not be flame cut.

POLYTIC-O

Characteristics and Composition

POLYTIC O is an iron-based metal cored wire designed to produce weld deposits containing evenly dispersed titanium carbides, in a martensitic matrix. POLYTIC Oexhibits excellent abrasion resistance, while maintaining toughness and impact resistance. It is best suited in applications with high stress and abrasion. POLYTIC O can be applied crack free, with proper procedures. Deposits are not machinable and can not be flame cut.

POLYTUNG-O

Characteristics and Composition

POLYTUNG O is a self shielding hardfacing wire with tungsten carbide particles in a high hardness iron matrix that provides excellent wear resistance for earth engaging tools and other high wear applications.

POLYVAN-O

Characteristics and Composition

POLYVAN O is an iron based metal cored wire, designed to produce weld deposits containing vanadium tungsten carbides. These carbides form during solidification of the weld puddle, and are evenly dispersed throughout a tough austenitic matrix. POLYVAN O’s wear resistance is higher than that of chromium carbide but less than tungsten carbide. POLYVAN O can be applied in multiple layers and on applications up to 900° F. Deposits are not machinable and cannot be flame cut.
