A key distinction between Rockwell testers and the Brinell, Vickers and Knoop testers is that the latter three use optical technology, while Rockwell does not—which generally makes it less costly, makes testing quick and easy, and the surface finish of the specimen is not critical. 

Component manufacturers across the manufacturing spectrum—such as in automotive, aerospace, electronics, medical, energy and other fields—must ensure that their parts meet engineers’ specifications.

Understanding the different hardness testing types and systems can be useful to determine an optimal solution. Hardness testing functionality has evolved and now users can dial into world-class instrumentation which more closely aligns with their applications at hand.

Many new products entering the market today are based on new materials and are manufactured using novel processes. These new materials are playing increasingly important roles—supporting innovation and boosting competitiveness in technology-driven industries.

Mitutoyo America Corporation announced the release of the latest Rockwell Hardness Testers in its HR-530 Series, including the HR-530 (maximum specimen size height:  250 mm; depth: 150 mm) and the HR-530L (maximum specimen size height: 395 mm; depth 150 mm). 

Buehler is introducing a Quick Ship program for the popular Wilson certified Rockwell hardness test blocks.  For ultimate accuracy and performance in tester verification, Buehler has calibration sets available for most Rockwell scales.  

The Indentron Series of Rockwell hardness testing systems from Ametek Test & Calibration Instruments features a unique cantilevered load arm configuration that provides an exceptional view of the indenter and test location.

By their nature, microhardness testers are delicate instruments. Extremely light forces must be accurately applied, and the resultant impressions must be precisely measured under high magnification.

Many new products entering the market today are based on new materials and processes. These new materials are playing increasingly important roles—supporting innovation and boosting competitiveness in technology driven industries.

574 Rockwell hardness testers are designed to meet a range of Rockwell testing applications within the automotive and aerospace industries.
