Hardness is one of the most important properties of engineering materials. It provides indication for material selection and also quality assurance tests for wear resistance. A Hardness Testing Machine was Designed, Fabricated and Tested. Four samples used for the machine evaluation were, mild steel, brass, Aluminum and copper. Standard Test procedure for Brinell Hardness Test was followed in testing for the fabricated Hardness Testing machine. Eight varying loads were applied at intervals of 30secs. The results recorded were represented graphically; results show that mild steel is the hardest of the samples followed by brass, Aluminum and copper in order of decreasing Hardness.
