Abstract
Research has been conducted which aims to determine the results of thecalculation of thermal expansion coefficient on aluminum material from used pistonmaterial which will be applied to nuts and bolts using variations at temperaturesaging 100 ° C, 125 ° C, 150 ° C and 5 minutes aging time , 35 minutes 65 minutes inhe T6 heat treatment process against the thermal and microstructure properties ofaluminum composites with reinforcement of coal base ash. From the results of themicrostructure test it can be seen that the aging temperature variations and agingimes have little effect on the size of the crystals produced. It can be seen from thecrystal size results that the aging temperature increases and the longer the agingsize the crystalline size increases and also the decrease TMA with a variation ofaging temperature of 100 ° C and a time of 35 minutes aging has a low coefficient ofvalue. the lower the rate of 19.26 ppm ° C-1. the lower the value of thermalexpansion coefficient will be better because it can be applied to components thatwork at high temperatures
