The hardness is not the fundamental physical property. It is the characteristics of a material. It is the indentation resistance measured by the permanent indentation depth. In simple terms, when a load or force is applied to cause indentation, the smaller indentation means a harder material and bigger indentation means a less hard material. Different types of hardness tester Australia equipment are available for checking the hardness characteristics of different materials. The purpose of this type of testing is to know the tensile strength and hardenability of a material. It helps find the material’s toughness, wear resistance, functional capability and impact resistance levels. The testing equipment and method are selected based on the type, scale, thickness, sample size, shape and gauge of the material. A microhardness tester is needed to measure the hardness of very small parts and sections. The expected hardness should be guessed before the testing. It helps select the right testing equipment.
