SUITABILITY OF ADO-EKITI (NIGERIA) NATURAL MOULDING SANDS FOR USE AS FOUNDRY SANDS IN PRODUCTION OF ALUMINUM ALLOY CAST

Abstract

Adequate application of sand casting processes in Aluminum casting can improve the economic activities of Nigeria through industrialization. Samples of natural moulding sand were collected from three different moulding sand deposits within Ado-Ekiti metropolis. The samples’ properties were evaluated using American Foundry Society standards. The samples were used to produce aluminum alloy cast specimens and their mechanical properties were evaluated. The results revealed that the properties compared favourably with standard values as indication that the moulding sands are suitable materials for aluminum casting. Thus, effective application of the sample sands will enhance industrialization, job creation and the nation self-reliance.
