Hardness tests, principally to Brinell Method HBW2,5 and/or Rockwell tests (e.g. HRB) are carried out on steel and aluminium rims for production control purposes and also to confirm strength characteristic values. 

With the Zwick/ZHU250 universal hardness tester, tests with loads up to 250 kg can be performed, using controlled closed loop technology, for all classical hardness testing methods (Brinell, Rockwell, Vickers, Knoop and ball indentation hardness) for metals and plastics applications. Large components are accommodated without difficulty in the 250 x 300 mm (D x H) test area.
