The effect of the casting temperature on the hardness, wear resistance and flowability or coliability of the ASM 356 aluminum alloy has been studied. Casting temperatures of 680, 700, 750 and 800 ° C were considered. The hardness test was performed according to ASTM E-140, the wear resistance test was performed according to ASTM G-77, and for the flowability or coliability test the specimen was spiral according to the Chneider method, cast in sand mold. According to the results obtained show that the hardness decreases with the increase of the casting temperature from 95.30 HB to 680 ° C to 81.50 HB for 800 ° C and the wear resistance also decreases as the casting temperature increases because with the Increase in temperature, the grain size grows in the structure, making it less compact. And in terms of fluidity or coliability measured in centimeters, this increases with the increase...
