What is UNS C46400 Naval Brass?
UNS C46400 is a naval brass and is predominantly copper with a controlled amount of zinc with an addition of tin. It is due to the tin that it offers such great corrosion resistance against saltwater in which normal brass would be unable to cope.
Chemical Composition of UNS C46400
| Element | Content (%) |
| Copper (Cu) | 59.0 – 62.0 |
| Zinc (Zn) | Balance |
| Tin (Sn) | 0.50 – 1.00 |
| Lead (Pb) | Max 0.20 |
| Iron (Fe) | Max 0.10 |
The addition of tin helps protect the alloy against dezincification and erosion caused by seawater exposure.
