Magnesium alloys have been widely applied in the automotive world cars or motorcycles and aircraft engines. This is because the weight of the magnesium itself is very lightweight and have high strength. Magnesium alloys have good thermal conductivity, high elastic modulus and good mechanical properties. Magnesium in engineering applications is usually alloyed with elements such as Al, Ag, Mn, Zn, Si, Zr and RE (rare element). Magnesium alloys with zinc are mostly found and used. This research has been carried out precipitation hardening treatment-Mg alloy-0.5Y 6Zn using variable temperature 150oC, 175oC and 200oC with a holding time of 12 hours, 24 hours and 36 hours. The results show microstructure formed is αMg, MgZn, and Mg3Zn6Y (i-Phase). The formation of precipitates during the process of aging raise hardness values up to 75.8 BHN. Aging treatment reduces the thermal resistance of the alloy Mg-6Zn-0.5%Y.
