Osprey CE 17(27Si/73Al)

Typical applications include electronic packages, carrier plates for polymeric PCBs, and stamped components.

  • Offers exceptional CTE matching (16.0ppm/°C) to polymeric PCBs (eg. FR4) and improved CTE matching to electronic circuit boards compared to Al.
  • One third the weight of Copper.
  • Machining is similar to conventional Al alloys.
  • Weldable and plateable.
