This page offers a detailed and practical overview of Brass C46400. In addition, it explains how MFG SOLUTION integrates this alloy into high-quality, cost-effective manufacturing solutions that meet global standards while remaining SEO-friendly and easy to read.
What Is Brass C46400?
Brass C46400 is classified under the UNS C46400 standard and is widely referred to as Naval Brass. Compared with standard yellow brasses, this alloy includes tin, which significantly improves resistance to dezincification and corrosion in saltwater environments.
Because of this unique composition, C46400 performs well in marine hardware, shipbuilding components, offshore equipment, and industrial systems exposed to moisture. Therefore, it has become a trusted material for applications where ordinary brass may fail over time.
Chemical Composition of Brass C46400
| Element | Typical Composition (%) |
|---|---|
| Copper (Cu) | 59.0 – 62.0 |
| Zinc (Zn) | Balance |
| Tin (Sn) | 0.75 – 1.25 |
| Lead (Pb) | ≤ 0.25 |
| Iron (Fe) | ≤ 0.10 |
| Others | Trace |
This carefully balanced composition improves corrosion resistance while maintaining good strength and workability. At the same time, it allows reliable machining with proper tooling and process control.
