Product feature:
Hardness is one of the important indexes of mechanical properties of materials, and hardness test is an important means to judge the quality of metal materials or parts. Since the hardness of metals corresponds to other mechanical properties, most metal materials can be approximated by measuring hardness to calculate other mechanical properties, such as strength, fatigue, creep and wear.
The electric Rockwell hardness tester adopts the automatic loading and unloading test force mechanism, the test force transformation is obtained by the rotation of the variable load hand wheel, the operation is simple and rapid, in addition to the dial to zero, there is no artificial operating error, with high sensitivity and stability, suitable for the hardness determination of carbide, carburized copper, hardened copper, hard cast iron and aluminum alloy, copper alloy and malleable cast iron.
Application：
Suitable for quenching, quenching and tempering, annealing, chilled castings, malleable castings, hard alloy steel, aluminum alloy, copper alloy, bearing steel and other hardness determination.
