Abstract
The fluidity of the aluminium alloys decreases by increasing the volume fraction of oxide inclusions while recycling aluminium alloys and which in turn affects the castability of the materials. In the present investigation, the influence of scrap additions of A206 and Al–4Ni alloys on the fluidity of A206 alloy has been investigated for recycling. The measurements of the fluidity were achieved with plus type thin cross-sectional fluidity test. The pattern consists of cross sections 2, 4, 6 and 8 mm in order to make green sand moulds with respectable reproducibility. The effect of recycled alloys on fluidity has been compared with soapstone powder mould coating to that of the A206 alloy without coating. The results revealed that the fluidity decreased by an increase in the recycled alloy. It was observed that the fluidity was noticeably increased at 750 °C pouring temperature, particularly for the green sand moulds coated with soapstone powder.
