Extensively used to test the hardness of materials through the scale of penetration, these testing machines are delivered to our clients without any delay. Available in wide range of specifications, our Brinell Hardness Testing Machine is highly acknowledged across the market due to its greater efficiency, accurate measurement and easy operation. Further Details: The Brinell scale characterizes the indentation of an indenter, loaded on a material test-piece. It is one of several definitions of hardness in materials science A high-accuracy deadweight Rockwell hardness tester that is designed for lab testing. Unique design eliminates frictional inconsistencies. Even tests inside diameters without fixturing. Regular, superficial and combination units available to operate in all Rockwell scales in regular and superficial Rockwell ranges available in several capacities Methods All Brinell tests use a carbide ball indenter. The test procedure is as follows: The indenter is pressed into the sample by an accurately controlled test force The force is maintained for a specific dwell time, normally 10 - 15 seconds After the dwell time is complete, the indenter is removed leaving a round indent in the sample The size of the indent is determined optically by measuring two diagonals of the round indent using either a portable microscope or one that is integrated with the load application device The Brinell hardness number is a function of the test force divided by the curved surface area of the indent. The indentation is considered to be spherical with a radius equal to half the diameter of the ball
