Characterization of an Al-Cu alloy using fly ash and …
Since graphite and fly ash particles are thin and strong, they can be used as reinforcing materials. The process of stir casting was used to make the composite. Fly ash and graphite particles were also added to the molten Al-Cu alloy in amounts of 3%, 6%, and 9%, respectively. After that, the mechanical properties of the composite were glanced at.
