PACE Technologies B1500 10 mm Ball Brinell Test Block for All Hardness Ranges, 1500 kg Load

The Brinell hardness test measures the diameter of an indentation produced by a hardened steel or tungsten carbide ball pressed into the test surface under a known load. Standard testing uses a 10 mm diameter ball with loads ranging from 500 to 3000 kgf. The load is typically applied for 10-15 seconds for ferrous metals and up to 30 seconds for softer non-ferrous metals to allow for creep.

The Brinell Hardness Number (HBW for tungsten carbide ball, HBS for steel ball) is calculated by dividing the applied load by the spherical surface area of the indentation. Tungsten carbide balls are required for materials harder than approximately 450 HBW to prevent ball deformation. The large indentation size makes Brinell testing ideal for coarse-grained materials, castings, and forgings where microstructural inhomogeneity might affect smaller indentation tests.

All Brinell Test Blocks come certified to applicable standards. PACE Technologies adhere to a strict procedure for calibration process, and the accuracy of PACE Technologies tester is maintained using a proving ring and load cell both traceable to N.I.S.T. The readings are done using a stage micrometer, which is also calibrated and traceable to N.I.S.T.

Applications:

• Testing large castings, forgings, and unmachined components with coarse grain structures
• Evaluating cast iron, aluminum alloys, copper alloys, and soft steels
• Correlating hardness with tensile strength using empirical relationships
• Field testing where portable Brinell testers can be used on-site
• Materials too soft or too coarse-grained for Rockwell testing
