Abstract


The purpose of this research is to know the effect of fly ash addition to the hardness and toughness of
material produced. In this research, it is known that aluminum cans waste as a matrix and ash waste coal fly
as reinforcement. The tools and materials used in the research are furnace, ladle, stircoast, blower, sand,
pattern, waste cans and coal fly ash waste. This research procedure starts from the process of making
specimens with alloy (%) aluminum-fly ash. Fariation of aluminum-fly ash alloy is 80%: 20%, 70%: 30%,
60%: 40%. In Vickers hardness testing seen at the lowest Al-FA hardness level was on specimens with
variation Al 60%: FA 40% ie 49.78528 kg / mm² and highest Al-FA hardness was in specimens with
variation Al 80%: FA 20 % alloy that is equal to 60,25068 kg / mm². Meanwhile, on the toughness impact
test, the highest impact strength value is in Specimens with Al 60% variation: FA 40% alloy is 0.162 J / mm²
and the lowest impact strength is in specimen from 100% Aluminum variation of 0.056J / mm².
