The brinell test, another common hardness test type, comprises of applying a constant load or force, typically between 500 and 3000 kgf, for a specified time (from 10 to 30 seconds) with the help of a 5 or 10 mm diameter tungsten carbide ball. The load time period is needed to make sure that plastic flow of the metal has stopped.

Hardness testing of metals is routinely performed to assess the value of treatments and coatings. Near philadelphia, pa in the united states, performs hardness testing on metallic materials. The test methods include a variety of micro hardness and macro hardness testing services, such as rockwell, superficial rockwell, brinell, vickers and knoop testing.
Hardness – determined through brinell hardness test; this is the measure of the metals resistance to corrosion, wear, or erosion. Impact resistance - determined through impact test; this is the measure of resistance to impact of the metals after machining, heat treatment, or casting procedures.
