Al-Si powder Al-Si powder is an alloy powder mainly composed of Al and S Al and 11.7% Si can form eutectic alloy; When the silicon content is low, the ductility of Al Si alloy is better, and it is often used as solder; High Si Al-alloy has low density and coefficient of thermal expansion, good thermal conductivity, high specific strength and stiffness, weldable substrate and easy precision machining. It is a promising electronic packaging material, especially in aerospace, space technology and portable electronic devices. Chemical Composition（wt%） Si Fe O H₂O Al 4-55 0.2 0.12 0.1 Bal.
