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 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.
POLYCHROME 100 is an iron- based high chromium carbide metal cored wire, designed for metal to metal earth applications with severe abrasion and light to moderate impact. POLYCHROME 100 develops a fine cross check pattern and is used for a wide range of applications in the crushing, grinding, and construction industry. Deposits are normally limited to two layers. Deposits cannot be machined or flame cut.
POLYCHROME 100 C—an iron based high chromium carbide metal cored wire, designed for metal to earth applications with severe abrasion and light to moderate impact. POLYCHROME 100C develops a fine cross check pattern and is used for a wide range of applications in the crushing, grinding and construction industry. A unique attribute of POLYCHROME 100C is that it can be applied in multiple layers using stringer beads and special procedures (contact Polymet for more information). This process is used to refurbish coal and cement pulverizer rolls and rings. Deposits are normally limited to two layers, and cannot be machined or flame cut.
PMET 720 is a 420 stainless steel wire, specifically designed for arc spray processes. PMET 720 forms a dense, well bonded coating, with excellent wear resistance and good corrosion resistance. It is widely used for machine elements repair, dimensional restoration, and wear resistant application. PMET 720’s low shrink rate characteristics allows for increased coating thickness on parts requiring heavier coatings.

PMET 885 is a solid wire specifically designed for arc spray systems. It is self-bonding to most materials and requires minimal surface preparation. Bond strengths in excess of 9000 psi can be achieved on clean smooth surfaces. Roughening of the surface by machining, grit blasting or grinding can increase the bond strength up to 10,000 psi. PMET 885 exhibits good resistance to high temperature oxidation and abrasion, and excellent resistance to impact and bending. PMET 885 can be machined and ground to a finish of 5 micro inches. It is a self-bonding, one step material and is also suitable for the build-up and dimensional restoration of nickel-based alloys. PMET 885 is widely used as a bond coat for subsequent thermal spray topcoats and as a one step build up material for dimensional restoration of aircraft engines.
