The Brinell Hardness Test is suitable for measuring the overall hardness of copper bushings, especially the softer copper alloys. The test is performed using a steel or carbide ball of a certain diameter, which is pressed into the surface of the copper sleeve with a constant force, and the hardness value is calculated from the diameter of the indentation.
Rockwell Hardness Test is faster and suitable for measuring copper bushings with higher hardness. The hardness value is obtained by measuring the depth of the indentation after it is pressed into the metal surface. Commonly used scales are HRB (for softer materials) and HRC (for harder materials).
The Vickers Hardness Test can be used to measure very small areas of copper bushings and is suitable for a wide range of copper alloys. The hardness value is calculated by pressing a diamond four-pronged conical indenter into the surface of the copper sleeve and measuring the diagonal length of the indentation. The advantage of Vickers hardness is that it has a wide range of applications and is suitable for measuring thin or small copper parts.
The Shore Hardness Test is mainly used for softer copper alloy materials and is commonly used for rubber and plastic parts. When measuring copper bushings, a suitable indentation tool is used to assess the hardness of the material.
