Abstract

The process of forming aluminum can be done in various ways, one of which is by using a casting or mold method. To make castings, processes must be carried out such as melting metal, making molds, pouring, and cleaning castings. Aluminum was chosen because it has light properties and its strength can be formed by combining it with other elements. The purpose of this study was to investigate the hardness of the test material and to analyze the microstructure of the test material. The method used in this study was the Vickers test method. The purpose of the Vickers hardness test was toidentify the level of hardness on the specimen from the results of variations in the stirring of the specimen. The conclusion of this study was the experimental results of hardness testing obtained an average value of hardness in each specimen of 858.27 N/mm and the microstructure of the test material referred to the aluminum. The micro structure of each code had a different form.
