What materials are Vickers hardness testers suitable for measuring?

The Vickers hardness tester is suitable for the qualitative measurement of high-hardness material properties. If repeated testing is required, the repeated trials usually begin with cemented carbide inserts, and then gradually move to higher-hardness and more expensive inserts.
Modern insert geometry, high-rigidity tool holders, and precise machining routines enable lower-priced cemented carbide inserts to handle demanding cutting tasks. If cemented carbide inserts are not used, other inserts must be selected based on specific circumstances, but the vast variety of materials can still pose significant processing difficulties.
