| (7) | Ultimate tensile strength x1000 P.S.I. |
| (8) | 0.2% offset yield strength x 1000 P.S.I. Yield strengths are not used or accepted as specifications by brass mills; but, because of their usefulness, values are given here for design purposes |
| (9) | % elongation in 2". Elongation values vary considerably with thickness. The rolled temper data given are based on thicknesses ranging from .010" to .035" strip. |
| (10) | Approximate Vickers hardness - Hv unless otherwise specified. |
