Effect Of Alloying

Recently, demand of aluminum alloys for manufacturing in components with high thermal conductivity application increases. However, the most aluminum die casting alloys exhibit very lower thermal properties, about only a half of pure aluminum. In die casting alloys, alloying elements are essential to obtain sufficient fluidity and mechanical strength, therefore, in this study, the effect of alloying elements, Si, Cu, Mg, Fe and Mn, on thermal conductivity, die casting characteristics and mechanical properties were analyzed and the appropriate amount of each alloying element were investigated. The results showed that Mn had the most deleterious effect in thermal conductivity and Si and Fe contents were important to improve fluidity and strength. The alloy with 1.5~2.0wt.%Si and 0.6wt.%Fe showed very good combination of high thermal conductivity and sufficient casting characteristics.

The Impact

Abstract Recent research in the process of aluminum alloy die castings production, which is nowadays deeply implemented into the rapidly growing automobile, shipping and aircraft industries, is aimed at increasing the useful qualitative properties of the die casting in order to obtain its high mechanical properties at acceptable economic cost. Problem of technological factors of high pressure die casting has been a subject of worldwide research (EU, US, Japan, etc.). The final performance properties of die castings are subjected to a large number of technological factors. The main technological factors of high pressure die casting are as follows: plunger pressing speed, specific (increase) pressure, mold temperature as well as alloy temperature. The contribution discusses the impact of the plunger pressing speed and specific (increase) pressure on the mechanical properties of the casting aluminum alloy.
