Brinell Hardness Testers

About Brinell Hardness Testers

A Brinell Hardness Tester is a precision material testing instrument used to determine the hardness of metals and alloys by measuring the resistance of a material to indentation. It applies a specific load through a hardened steel or tungsten carbide ball indenter, and the resulting indentation is measured to calculate hardness value.

This tester is widely used in metallurgical laboratories, foundries, steel industries, automotive sectors, and quality control departments for material evaluation and inspection.

Key Features

• High-capacity loading system for heavy-duty testing
• Steel / tungsten carbide ball indenter
• Digital / analog measurement system (model dependent)
• Rigid and vibration-free heavy frame construction
• Hydraulic or motorized load application system
• Adjustable test load and dwell time settings
• Optical microscope for indentation measurement
• Conforms to ASTM / ISO / BIS hardness testing standards

Working Principle

The Brinell hardness test works on the principle of indentation resistance measurement. A hardened ball is pressed into the surface of a test specimen under a known load for a fixed time. After removing the load, the diameter of the indentation is measured, and the Brinell Hardness Number (BHN) is calculated.
