Abstract

Recycling aluminium (Al) waste by secondary smelting production saves 95% energy had encourages a new alternative recycling technique known as the in-situ casting or melting to transform waste into product directly. Therefore, aluminium (AlSi7Mg) machining chips with flux addition were heated for 30 minutes in a laboratory furnace at 650°C and 700°C. The physical of Al chips turned from sparkling silvery grey to dusty grey after being heated indicating oxidation. The machining chips had partially melted and fused together however being interrupted by thin oxide layer. Scanning electron microscope (SEM) equipped with energy dispersive spectroscopy (EDS) reveal the Al and oxygen (O), while x-ray diffaction (XRD) analysis confirmed aluminium oxide (Al2O3) present in the fused Al chips.
