Description

Technical Field

[0001] The utility model belongs to the technical field of alloy workpiece production, and specifically relates to an alloy hardness testing device. Background Art

[0002] Alloy refers to a solid product with metallic properties obtained by mixing and melting one metal with another or several metals or non-metals, cooling and solidifying. There are many steps in the alloy production and processing, and various tests are required in the alloy production process to ensure that the product quality of the alloy workpiece meets the required standards. One of the tests is the hardness test of the alloy workpiece, and a hardness tester is required for the hardness test.

[0003] Metal hardness testing is the fastest, most economical and simplest test method for evaluating the mechanical properties of metals. The main purpose of hardness testing is to determine the suitability of materials, or the effect of special hardening or softening treatments performed on the materials for their intended use.
