Introduction
A Hardness Tester is a testing instrument used to determine the hardness of a material, while a hardness test is a means to judge the quality of a metal material or product part. The so-called hardness is the ability of a material to resist the press-in of another object that does not have residual deformation itself under certain conditions. The greater the resistance, the higher the hardness, and vice versa, the lower the hardness.
In the mechanical property test, measuring hardness is the easiest, most economical, and fastest method, and it is also one of the measures to check the quality of products in the process of machinery manufacturing. Since the hardness of metals corresponds to other mechanical properties, most metal materials can be approximated by determining hardness to deduce other mechanical properties, such as strength, fatigue, creep, wear, and internal damage.
Scope of application
It is suitable for surface quenched steel, material surface heat treatment and chemical treatment layer, copper, aluminum alloy, thin plate, galvanized, chrome-plated, tin-plated materials, bearing steel, cold hard castings, etc.
