The Brinell Hardness Tester is a precision instrument used to measure the hardness of metals and alloys, especially materials with coarse structures such as castings and forgings. Based on the Brinell hardness testing method, this device applies a fixed load through a hardened steel or tungsten carbide ball indenter and measures the diameter of the indentation left on the material surface.

Product Introduction

The Brinell Hardness Tester is a precision instrument used tomeasurethe hardness of metals and alloys, especially materials with coarse structures such as castings and forgings. Based on the Brinell hardness testing method, this device applies a fixed load through a hardened steel or tungsten carbide ball indenter and measures the diameter of the indentation left on the material surface.

Widely used in metallurgical, foundry, engineering, and quality control laboratories, the Brinell tester provides accurate and repeatable measurements of materials such as cast iron, steel, aluminum, copper, and brass. Available in both manual and digital models, it ensures reliable testing with robust mechanical structure and easy operation.
