Zuoyuan high silicon aluminum alloy


Zuoyuan high-silicon aluminum alloy material (silicon content 27%-70%), cost-effective, high practicability, by increasing the supersaturation of Si in the aluminum matrix, the formed silicon particles reinforced aluminum matrix composite material. High-silicon aluminum alloy materials with different properties can be obtained by adjusting the volume fraction of silicon, with low thermal expansion coefficient CTE, low density, high thermal conductivity, good electrical conductivity (with excellent electromagnetic interference/radio frequency interference shielding performance), high hardness, excellent thermomechanical stability, high density, easy machining, easy plating protection, compatible with standard microelectronics assembly process, etc.
