HARDNESS OF BRASS

While Brinell Hardness is not a common­ly required property of brass and bronze casting alloys, it is ap­parent that in materials witll such a range of tensile strength there will be considerable hardness variation. roo.
The nighest hardness values found are in some of the alu­minum bronzes; up to 350 BHN or higher. Other commonly used copper alloys offer bardne$s values from 50 BHN to 250 BHN.
