Calcium metal as a scavenger for antimony from aluminum alloys
The aluminum-silicon alloys were prepared in a high-frequency induction furnace from primary A356.2 ingot of commercial purity. Each melt was grain-refined with aluminum-titanium rod, modified with aluminum-strontium-silicon rod, and degassed with dry nitrogen. Five heats were prepared at each target level of Sb: 0.00, 0.05, 0.10, 0.15 and 0.20
