Thermal management products possess the light weight-lower CTE-high thermal conductivity features,such as the Si-30wt.%Al(AlSi70) alloy optical and opto-electronic housings.
Main attributes of AlSi70(Si-30Al Controlled Expansion alloy) alloy:
●Low CTE and CTE match to components, and stable with temperature;
●High thermal conductivity;
●Manufacturability (ease of machining and plating)
The raw materials of AlSi70 alloy blanks:
