...aluminium, steel, and iron. Using the Rockwell scale, the measurements of hardness of each material were determined. The same process was repeated five times and an average for the measurements determined. The key objectives of this experiment are; to establish the hardness measurements of aluminium, brass, steel, and iron, and to compare and contrast the hardness of aluminium, brass, 1018 steel, and cast iron. Cast iron was found to have a higher harness value than the other metals. Introduction. Rockwell scale involves a scale... Hardness test. Hardness refers to a measure of the extent of resistance for a solid matter towards different types of permanent shapes whenever some amount of force is...
