A comprehensive portfolio of hard facing alloys using the latest application technology over a diverse range of industrial applications.


Hardfacing Spray Powders

There are 2 basic types of powder:

  • Base powders with a hardness scale of 20 – 60 Hrc
  • Ready mixed powders with cast tungsten carbide particles 40 - 80µ to give increased wear resistance
    • These are atomised Nickel alloy powders containing Nickel, Chromium, Boron, and Silicon.
    • Boron and Silicon are good fixing elements.
    • Hardness values are dependent upon the Chromium-Boron-Silicon content.


Flexible Electrode – Hardfacing Cord

Cord composition:

  • Central metal core : 1.2mm diameter Nickel wire.
  • Matrix : Nickel based powder - hardness value 40Hrc (content 35%).
  • Cast or Spherical tungsten carbide particles – with grains of varying shapes and sizes – hardness value 2000 – 3000HV (content 65%)


Two Types of TENROCK

  • Tenrock 2000 – Cord containing cast tungsten carbide : Good for wear resistance.
  • Tenrock 3000 – Cord containing spherical tungsten carbide : Increased shock / impact resistance.

Weld Properties

  • Dense homogeneous coating from 2 – 10mm thickness.
  • High wear resistance.
  • Good corrosion resistance.
  • Average density 13.6 kg/dm3.
  • Easily applied by any competent welder.
