Osprey CE 11 (50Si/50Al)

  • Offers improved CTE matching (11.0 ppm/°C at room temperature) to electronic circuit boards compared to aluminium or copper. In many cases, reliable carrier for most ceramic substrates and device materials, including alumina and GaAs.
  • One third the weight of copper.
  • Lower cost material and easy to machine with lower machining costs vs. CE7 or CE9. Weldable and plateable.
  • Typical applications include electronic packages and components for inertial systems.
