TYPES OF HARDNESS TESTING MACHINES FOR MATERIALS

We mostly use 7 types of hardness machines in industries to check the hardness of materials. like..

• Rockwell Hardens Machines : -

This Rockwell hardness machine is used to determine the hardness of materials like ferrous, non-ferrous, copper, aluminum, alloys. It shows the direct hardness value.

• Brinell Hardness Machines : -

This Brinell hardness machine is used to know the hardness of materials like ferrous, non-ferrous, copper, aluminum, alloys. It shows a circle impression through which we need to know the hardness value.

• Vickers Hardness Machines : -

This Vickers hardness machine is used to know the hardness of materials like ferrous, non-ferrous, copper, aluminum, alloys. It shows an impression like a rhombus through which we     need to know the hardness value.

• Shore Hardness Machines : -

This machine is used to determine hardness value of materials like rubber, plastic, polythene. This machine directly shows the hardness value.

• Leeb Hardness Machines (Portable or Dynamic) :-

This portable hardness machine is used to determine the hardness of materials like ferrous, non-ferrous, copper, aluminum, alloys. It shows the hardness value, but it is only the conversion value of the dynamic hardness value. This machine does not show accurate value.

• Micro Hardness Machines (Micro Vickers) : -

This Vickers hardness machine is used to know the hardness of materials like ferrous, non-ferrous, copper, aluminum, alloys. It shows an impression like a rhombus through which we need to know the hardness value. This machine gives the most accurate value.

• Webster Hardness Machines : -

This machine is used to determine hardness and strength of aluminum and aluminum alloys. This machine shows the Webster Hardens value and through its conversion the strength can be known.
