Self-supported-compax-PCD-web.jpg

Hyperion Materials & Technologies manufactures free standing Compax® PCD die blanks for the wire-drawing industry. The polycrystalline diamond (PCD) cylinders are either electrically conductive (metal filled - MF) or thermally stable (TS). Both MF and TS grades are available in 5 and 25 micron diamond grain sizes with dimensional sizing from D-6 to D-30 and a sub-micron diamond grain size from D-6 and D-12.

PRODUCT DESCRIPTION

TS Grade

  • Catalyst metal removed
  • Thermally stable up to 1050°C in an inert or reducing atmosphere
  • Can be mounted using high temperature, high strength metal setting powders
  • Not electrically conductive: electrical discharge machining (EDM) not recommended for piercing/shaping
  • Use laser, ultrasonic, or needle piercing/shaping methods.

 

MF Grade

  • Metal filled, contains catalyst metal
  • Thermally stable up to 700°C
  • Do not exceed 700°C in blank mounting
  • Electrically conductive: EDM, laser, ultrasonic, or needle methods for piercing/shaping die bore may be used.

 

POLISHING

  • Diamond micron powder grade SJK-5 or GMM coating series recommended for final die bore shaping and polishing
  • For superior polish, use 0.25 μm or 0.5 μm graded diamond fines.

 

RECOMMENDED APPLICATIONS

TS or MF Grade

  • Drawing of high carbon steel tire cord
  • Drawing of smaller diameter and critical surface finish non-ferrous and ferrous wires.

TS Grade

  • High temperature drawing of tungsten/molybdenum.
