What is C46400 Naval Brass?
C46400 is a special brass alloy made mainly of copper and zinc, with a small addition of tin. This combination gives it excellent strength and resistance to corrosion, especially in saltwater and marine environments.
It is also known as Brass – Copper Alloy UNS C46400. The addition of tin improves resistance to dezincification and stress corrosion cracking, making it ideal for marine hardware and fittings.
In simple words, Naval Brass is “marine-grade brass” designed to handle harsh water conditions without losing strength.
What Are Forged Naval Brass Fittings C46400?
Forged Naval Brass Fittings C46400 are pipe fittings made by a forging process. Forging means shaping metal under high pressure. This process improves the internal grain structure of the metal, making it stronger and more reliable compared to cast fittings. These fittings are used to connect, redirect, or control the flow of fluids in piping systems.
Common Types We Supply:- Elbows (90° and 45°)
- Tees
- Couplings
