The influence of the AZ91 alloy home scrap addition to the metal charge on both the structure and the selected mechanical properties of pressure castings was examined in this article. Two heats were made using different components, the first with only pure AZ91 alloy ingots in the charge, and the second containing 30 wt % of home scrap. The hot chamber 3 MN machine was used for casting. The structures of the castings and their Brinell hardness were examined for both cases. A strong refinement of crystals was observed in castings made with the contribution of the recycled material. Any significant differences in castings hardness were not observed.
