Osprey CE 13(42Si/58Al)

Typical applications include electronic packages and components for inertial systems.

  • Offers improved CTE matching (12.8 ppm/°C at room temperature) to electronic circuit boards compared to aluminium, copper or steel.
  • 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, CE9 or CE11.
  • Machineable and Plateable
