Vadim Verlotski

For the production of car and motorcycle pistons, aluminum casting alloys from the AL-Si system (7-12% Si) are used. Manufacturing method: chill casting and pressure die casting.

Gedvidas Bikulcius

Dear V. Verlotsci, Thank you.

Ricardo Cruz Da Silva

Al-Si-Cu-Mg-Cr alloys are the most suitable for the production of automotive pistons due to their hardness and thermal resistance. Heat solubilization and artificial aging treatments are generally applied.
