1.abstract

the most used test with tensile test for metals and materials hardness, generally hardness represents resistance to deformation
this test have used copper alloys and mild steel. Rockwell hardness tester, vickers hardness tester as hardness tester was used
Rockwell hardness tester represents test results of copper alloy, 88 test results of mild steel, 94
Vickers hardness test of 0.1892 formula is used
Average d = 0.435mm of copper alloy by applying pressure to force 10 values ​​were obtained.
The case of mild steel with a force of 20 average d = 0.453 were obtained.
Results of this experiment, copper alloy, mild steel had a hardness of the order of a century.
And low hardness of the century, there was a lot more experimental DATA deviation.

2. For experimental purposes

1. The main purpose of the test to evaluate the mechanical properties of the material, representing the case of the resistance to deformation or rupture of certain conditions by measuring the hardness.
