Brinell Hardness Test

The Brinell Hardness Test is a mechanical test used to determine the hardness of metals and alloys by measuring their resistance to indentation. A hard steel or tungsten carbide ball is pressed into the material under a specific load, and the resulting indentation diameter is used to calculate the Brinell Hardness Number (BHN). This method is suitable for testing materials with coarse or heterogeneous structures, such as castings and forgings.

Applications

• Metals & Alloys:Measure hardness of steels, cast iron, aluminum, and non-ferrous alloys.
• Quality Control:Ensure material consistency and compliance with specifications.
• Heat Treatment Evaluation:Assess the effect of annealing, quenching, and tempering on hardness.
• Casting & Forging Inspection:Evaluate surface and bulk hardness in large components.
• Failure Analysis:Correlate hardness with wear, deformation, or mechanical failure.
• Research & Development:Support materials development, process optimization, and comparative studies.
• Industrial Applications:Applicable in automotive, aerospace, construction, and manufacturing industries.
