The influence of alloying elements on the die-casting performance of auto parts

Jan 11,2022


The addition of alloying elements to the die-casting of auto parts may cause precipitation hardening (age hardening), solid solution hardening, dispersion strengthening, grain refinement, changing metal and intermetallic phases, and inhibiting grain growth at high temperatures (for example, during annealing) ) G), wear resistance and other tribological characteristics. Auto parts die-casting strengthens and hardens the alloy through solid solution hardening mechanism without significantly reducing ductility. Auto parts die-casting, combined with silicon or zinc, can be heat treated by precipitation hardening, forging aluminum-zinc auto parts die-casting, aluminum alloy 356.0, aluminum alloy 713.0) Strengthened alloy.
