WC-6Co Thermal Spray Powder

  • Sintered and crushed powders are irregular.
  • The maximum service temperature is up to 500℃.
  • The dense coating has high hardness with excellent resistance to abrasive wear, fretting wear, adhesive wear, and erosion wear.
  • High fracture toughness.
  • Mainly used in mechanical parts, oil and gas equipment, metallurgical roller and pump seal, etc.
