Hardness is the property of a material enabling it to resist plastic deformation, usually by penetration of another object.
Rockwell, Vickers, Micro Vickers, Brinell or Universal, semi-automated through to fully automated, Tinius Olsen has many types of hardness testers available that can rapidly and accurately determine the hardness value of a wide variety of materials including metals, plastics, large parts, small precision parts. Whether you need bench-mounted testers, large-scale floor-mounted testers, or dedicated testers that are integrated into your production lines, we can help you with your application.
Tester configuration options include manual or motorized X/Y tables, Z-axis, multiple indenter positions, multiple objectives with anti-collision system and overview cameras in support of test piece positioning.
Types of Hardness test methods:
Rockwell (HR) : Indenting the test material with a diamond cone (HRC) or hardened (tungsten) steel ball indenter (HRB etc.)
Applying a preload of 10kgf firsthand the main test force of 60, 100 or 150kgf.
Brinell (HB) : Indenting the tested material with a 1, 2.5, 5 or 10mm diameter hardened steel or carbide ball subjected to a load/force ranging from 1 to 3000kg.
Vickers (HV) : Indenting the test material with a diamond indenter, in the form of an upside-down perfect pyramid with a square base and an angle of 136° between opposite faces, subjected to test forces of 1 to 120kgf.
Knoop (HK) : Indenting the test material with an ‘elongated’ diamond pyramid, subjected to test forces usually not exceeding 1kgf.
