Naval Brass is a high-strength alloy composed of copper, zinc, and a small percentage of tin, typically around 60% copper, 39% zinc, and 1% tin. This composition enhances its corrosion resistance, especially in marine environments, making it ideal for shipbuilding, propellers, and other marine applications. The tin content also improves its resistance to dezincification. Naval Brass is known for its excellent wear resistance, good machinability, and ability to withstand high-stress conditions. It maintains mechanical properties over a wide temperature range, making it a preferred material in demanding maritime and industrial applications.
