Product Description

Brinell, Vickers and Rockwell Hardness Testing Unit

Description:-

The Brinell, Vickers and Rockwell Hardness Testing Unit  consists of a hardness testing machine that determines the three main types of hardness (Brinell, Vickers and Rockwell) in metals, hard alloys, quenched steels, etc. Besides it can also be used to measure the hardness of other materials, such as rigid plastics, bakelite, etc.

The most common method used to calculate the hardness of a metal is measuring the indentation strength with the aid of a tool of specific  geometry. It consists on measuring the imprint generated when exerting a preset load on the test piece for a certain time.

A penetrating ball of specific diameter is used in the Brinell hardness test to press the surface of the test piece with a specific force. The  unit  employs balls of 2.5 mm. and 5 mm.

The Vickers method allows to measure the hardness of practically all metallic materials, regardless their state and thickness. It employs a square  base pyramid-shaped indenter. Such indenter is applied perpendicularly to the surface whose hardness is going to be measured.

The Rockwell method generates a small size imprint during the test. It employs small quenched steel balls of different diameter or cones made of  diamond for the indentation.
