AlSi

AlSi is an aluminum-silicon binary alloy that combines aluminum's light weight and corrosion resistance with silicon's hardness and thermal properties. It is widely used in cast and wrought forms across automotive, aerospace, and consumer electronics industries, where the aluminum-silicon composition enables excellent castability, moderate strength-to-weight ratios, and good thermal conductivity. Engineers select AlSi alloys over pure aluminum when increased hardness and wear resistance are needed, or over heavier alternatives when weight savings are critical.
