In automotive world, light and strong material is needed to increase energy efficiency. Beside light and strong, the material must have good erosion resistance because there is a lot of abrasive particle that can wear the component surface. By mixing aluminum and nickel metal element, the properties of the metal is becoming stronger, and more wear resistance so that this material can be the alternatives for some automotive component. The specimen that used in this research is Al-Ni alloy. The aim of this work is to study the effect of nickel addition to pure aluminum to its properties and its erosion resistance. Al, Al-Ni alloy, and Al-Ni rolled 4% were employed as air jet erosion test subject. The result of this test is wear loss of metal and it will converted into wear rate of metal. The result of this research is Al-Ni Alloy has the lowest wear rate and Al-Ni rolled 4% has the highest wear rate. Al-Ni has the lowest wear rate because the existence of Al3Ni phase that make the metal become harder so it will difficult for alumina particle to erode the metal surface. At the same time Al-Ni rolled 4% has the highest wear rate in this test. It caused by the existence of crack in Al3Ni phase that make the metal is easier to erode.
