Hardness testing of copper

Hardness testing of copper

Hardness testing of copper

(OP)
I am looking for a chart that shows correlation between vickers, or rockwell B numbers to tensile strength. I can find the charts for iron and stainless steels but all I can find for copper just show tensile strength. I want to take hardness readings and convert to ksi-psi. Thank you all.

RE: Hardness testing of copper

dentnbent... Might also find following useful...

ASTM E140 Standard Hardness Conversion Tables for Metals Relationship Among Brinell Hardness, Vickers Hardness, Rockwell Hardness, Superficial Hardness, Knoop Hardness, Scleroscope Hardness, and Leeb Hardness [typical hardness value-correlations for MANY ferrous/non-ferrous alloys]

NAS531 CHARTS, ROCKWELL HARDNESS [typical hardness values for MANY ferrous/non-ferrous alloys]

RE: Hardness testing of copper

To be legal, ASTM E140 only applies to 70-30 cartridge brass (Table 4) or CDA 102 through 142 (Table 7). The main problem, though, is that these conversions are only between hardness scales - they do not include tensile or yield strength. I am not aware of a rule of thumb conversion either...
