    Application Range

    Rockwell: It is used to measure Rockwell hardness of ferrous, nonferrous metals and nonmetallic materials. It is suitable for measuring Rockwell hardness of heat treatment materials such as quenching and modulation.

    • Surface Rockwell: It is used to measure the surface Rockwell hardness of the ferrous metal, alloy steel, hard alloy and metal after surface treatment (carburizing, nitriding and electroplating).
    • Plastic Rockwell: Hard plastics, aluminum, tin, copper, mild steel, synthetic resins, and friction materials.
