Baienwei AlSi alloy(Si content from 27%-70%) is a silicon particles reinforced aluminum matrix composites formed by improving Si supersaturation in aluminium matrix. AlSi alloys have the features such as low CTE, low density, high thermal conductivity, high electrical conductivity(excellent EMI/RF shielding performance), high hardness, good thermo-mechanical stability, hermeticity, machinability, platability and compatible with microelectronic assembly technology etc. 

Features:
Low CTE, adjustable;
Low density, lightest thermal management alloy material
high thermal conductivity;
High stiffness;
Readily machinable(CNC/EDM)
Readily platable(Au, Ag, Ni, Ti etc);
Readily weldable;
Environmentally friendly.
