Brinell hardness testing method is a tried and trusted regime of industrial metal testing that works well with coarse-surfaced and very rough metals that can’t be assessed by other methods, examples include forged or cast metals. It is a method often used with larger materials. The Brinell Method tests the metals for resistance to denting, thus indicating hardness. The Brinell makes indents in metal using a specific pre-set weight, usually a steel ball or other hard ball. The hardness is gauged by the size of the denting, the smaller the size of the dent, the harder the metal is. The process includes a number of steps and statistics which add up to the conclusion on the hardness level.
There are a number of designs of Brinell Hardness Testing machines on the market. So it depends on budget, needs and space of the buyer. Some machines have more advanced computer systems. It is important to have the right machine for your industry and your type, size and quality of metal. It is possible to get hybrid machines which can also carry out other forms of metal testing, for example, Rockwell Hardness Testing.
The Brinell Hardness Testing machine is in the form of a work station, at the work station, you place the metal to be tested in position on the machine place, set the computer, and the test metal is pressed with the required weight, the result is then measured and provides the hardness reading to specific Brinell Standards.
In the hands of a knowledgeable operator, the machines are safe, simple and generally accurate.
