The Impact G tester is engineered for testing rough and heavy metals, which makes it particularly suitable for materials with coarse microstructures. With an impact energy approximately nine times greater than that of the Impact D device, it is capable of testing materials up to 646 HB. This increased energy, combined with the larger diameter of its spherical tip, allows for accurate hardness measurements even on surfaces with minimal finishing.

The Impact G tester is ideal for use on cast aluminum, castings and forgings, cast iron, steel, and cast steel, where traditional devices may require finer surface preparation. Its ability to deliver precise results on rough surfaces provides a valuable tool for industries dealing with heavy-duty and structural materials, assuring reliable hardness testing in challenging conditions.
