Vickers
Vickers hardness testing is a popular choice of test method for all metals, and has the broadest range of hardness scale measurements out of all the hardness testing procedures.
The Vickers Hardness test uses a pyramid-shaped diamond indenter to carry out hardness testing. Like the other tests, the indenter is placed under a load and the permanent indentation is measured. However, this test often uses much lighter loads and can be used on softer materials.
The size, shape and the precise required location of the hardness test determines the use of the Vickers Hardness test method.
The versatility of the Vickers Hardness test is that is covers a wide range of materials and properties.
