HBE-3000A Electronic Brinell Hardness Tester For Ferrous And Non Ferrous Metals
HBE-3000A Electronic Brinell Hardness Tester For Ferrous And Non-Ferrous Metals
HBE-3000A electronic Brinell hardness tester is suitable for measuring the Brinell hardness of ferrous and non-ferrous metals. This machine adopts closed-loop sensor loading and electronic control system, and has 10-level test force. This machine has the characteristics of high precision, high repeatability and stability, and easy operation.
Scope of application:
Brinell hardness uses a large test force and a large indentation diameter. It is suitable for hardness testing of metal materials with large grains, such as cast iron, non-ferrous metals and alloys, various annealed, quenched and tempered steels, especially for Softer metals such as pure aluminum, lead, tin, etc.

The Brinell hardness tester uses the oldest method of hardness testing commonly used today. It was invented in Sweden by Dr. Johan August Brinell in 1900. This test is often used to determine the hardness of castings and forgings whose grain structure is too course for accurate Rockwell or Vickers testing.
In this test method, a predetermined force (F) is applied to a tungsten carbide ball of fixed diameter (D) and held for a predetermined time period, and then removed. The spherical indenter creates an impression (permanent deformation) on the test metal piece.
