Osprey Metals
supplier of low expansion, highly conductive, light-weight, machinable metallic alloys for thermal m
Osprey Metals, a member of the Sandvik group of companies is the world leader in gas atomising technology. This process has been used to develop a novel family of Si-Al alloys that combine a low CTE (controllable between 5 and 11ppm/K), with good conductivity (>130 W/mK) and low density (<2.5gm/cc). The alloys are machinable using conventional techniques and can be plated in the same way as Al. The CTE of the alloys is constant with temperature.
