Effects of the ratio of the cooling behavior of aluminum alloy anti-freeze-Silicon-copper grades 319 through recycling. Reinforcement steel is commonly 0.8 is useful for mechanical strength aluminum used in forming with mechanical (wrought). The appropriate amount of steel, s/s (0.3) will increase the strength of the work pieces. The aluminum used in the casting section is useful for forming grades used by MOL (permanent mold), but there will be deterioration for the use in aluminium casting. When the steel is not suitable due to the form of the Beta phase. Lamella in pieces of casting characteristics
