Question regarding Brinell/Vickers Hardness Test
Vickers Hardness Test
Question : For Vickers Hardness Test to test the material hardness we uses different force [kfg], Why do we need to use different force like 1kgf and 5kgf?
Brinell Hardness Test
Question : Pure Copper : Require force is 62.5
Steel : Require force is 187.5
Why is there a change in the force require?

We use different loading forces depending on the softness of the materials. Softer materials require less force to achieve a certain deformation, while harder materials resist deformation and require a higher load/force to achieve a certain deformation. Each test is based on a certain geometry of the indentation within some limited range.
Note there are several hardness tests, and they can be correlated.
