NOTES

(1)Lbs.per cubic inch @ 60°F (annealed)
(2)Elastic modulus in tension x 106 P.S.I.
(3)% IACS at 68°F
(4)BTU per sq. ft. per hour per °F at 68°F
(5)Inches per inch x 10-6 from 68°F to 572°F
(6)Approximate relative cost based on ETP copper as 1.00; .025" x 1.00" strip in 10 m lbs. quantity
(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.
