Abstract:

The objective of this study was to determine the dezincification rate of commercially available valve stems containing varying amounts of zinc. Potentiostatic anodic polarization tests were conducted on copper electrolytic tough pitch and four copper alloys - copper alloy 377 forging brass, ASTM b140 Alloy A leaded red brass, ASTM B62 85-5-5-5, and copper alloy 624 aluminum bronze - in laboratory tap water at 25C 77F and 50C 122F and in 0.5 molar aqueous sodium chloride 0.5M NaCl at 25C.
