Material Hardness Tester

Material hardness testers are instruments used to measure the hardness of various materials. They are commonly used in industries such as manufacturing, engineering, and quality control to determine the resistance of a material to indentation or scratching.

These testers typically work by applying a specific force or load onto the surface of the material and measuring the depth or size of the resulting indentation. The hardness value is then determined based on the applied load and the size of the indentation.

There are different types of material hardness testers available, including:

1. Rockwell Hardness Tester: This tester uses a diamond cone or a hardened steel ball to apply the load onto the material surface. The depth of the indentation is measured, and the hardness value is determined based on the Rockwell scale.

2. Brinell Hardness Tester: This tester uses a hardened steel ball to apply a specific load onto the material surface. The diameter of the resulting indentation is measured, and the hardness value is determined based on the Brinell scale.

3. Vickers Hardness Tester: This tester uses a diamond pyramid indenter to apply the load onto the material surface. The size of the resulting indentation is measured, and the hardness value is determined based on the Vickers scale.

4. Knoop Hardness Tester: This tester also uses a diamond pyramid indenter, but it measures the length of the indentation diagonals instead of the size of the indentation. The hardness value is determined based on the Knoop scale.

Material hardness testers are essential tools for quality control and material selection processes. They help ensure that materials meet specific hardness requirements and provide valuable information about a material's mechanical properties.

In the supply class Physical Properties Testing And Inspection, material hardness testers are categorized as instruments used for testing and inspecting the physical properties of materials. They fall under the supply group Instruments And Laboratory Equipment, which includes various instruments and equipment used in laboratory settings for testing, measuring, and analyzing different properties of materials.
