Data Sheet F3 - Cu Zn38 Sn1
(1970 Edition)
Wrought Materials - Special Copper-Zinc Alloys - Special Brasses
Common names: Naval Brass
A copper-zinc alloy with a duplex alpha-plus-beta phase structure, and containing tin; a small amount of lead may also be added to improve machinability. The alloy has good hot-working properties and the presence of tin improves corrosion resistance in marine and other mildly aggressive environments. The wrought material is generally supplied as plate, sheet or rod.
| COMPOSITION (weight %) * | |
| Cu | 59.5 - 63.5 |
| Sn | 0.5 - 1.5 |
| Zn | rem. |
* Leaded alloys containing up to about 2% Pb are also covered by this data sheet. In American practice, Cu Zn38 Sn1 may be inhibited with arsenic, antimony or phosphorus (0.02-0.10%).
