Brinell Hardness Testing Machine - High-accuracy Deadweight Design | Accurate Measurement, Timely Delivery, 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
