PMET 73-20-7
WC 20Cr 7Ni Tungsten Carbide Powder
Details
73% WC 20% Cr 10% Ni (Agglomerated and Sintered)
-45/+15 µm
PMET 73-20-7 is a tungsten carbide – chromium- nickel powder specifically designed for HVOF systems. It produces a hard, abrasive and corrosion resistant coating, with a service environment up to 1400° F (760° C). High chrome like finishes can be obtained by typical grinding or lapping techniques. PMET 73-20-7 is ideal for use in a wide variety of erosive and abrasive wear applications and corrosive environments. It should be used where added corrosion protection is required versus WC-Co coatings.
Applications:
- Oilfield Applications
- Chemical Processing Equipment
- Extrusion Screws
- Other Erosion and Abrasion Wear Applications

WC 17Co Tungsten Carbide Powder
Details
83% WC 17% Co (Agglomerated and Sintered)
-45/+15 µm
PMET 83-17 (WC 17CO) is a tungsten carbide powder for HVOF thermal spray coatings. It has a higher Co level that provides better toughness, impact strength, and ductility than the popular WC-12Co. The dense structure of the powder provides superior coating density and increased powder flow. It produces an abrasive coating with a service environment up to 900°F (482°C).
Applications:
- Shrouds
- Exhaust Fans
- Extrusion Dies
- Pump Seals
- Crushing Rollers
- Sucker Rod Couplings
