What are the different usage methods for different hardness testers?

Taiwan Nakazawa Co., Ltd. answers this question for you:
1. Brinell hardness testers are mainly used for testing castings, such as aluminum alloys, copper alloys, etc.
2. Vickers hardness testers are used for measuring the Vickers hardness value of thinner workpieces; Vickers hardness testers are primarily for testing relatively thin small products or products after heat treatment.
3. Rockwell hardness testers: This type of hardness tester is mainly used for products after heat treatment and high-hardness products; for example, steel materials and metal material products can all be tested with it.
4. Leeb hardness testers are portable hardness testers used for measuring the hardness value of products that are not suitable for disassembly or are relatively large. They are primarily for testing the hardness of large products, where the weight of a single product must be greater than or equal to 3kg, such as molds, etc. The advantage of Leeb hardness testers is that they are convenient to carry, as most are portable. They can be used on the production line or in the laboratory, unlike desktop models that cannot be moved.
