Superior Corrosion Resistance for Marine Applications

IS 291 GRADE 1 Naval Brass Rods are engineered for enduring harsh marine environments, thanks to their excellent corrosion resistance in seawater. The combination of copper, zinc, and a small percentage of tin enhances their ability to withstand salt water exposure, making them a reliable choice for shipbuilding, marine hardware, and condenser plates.


Versatile Uses Across Industries

Possessing good machinability and a smooth, polished finish, these naval brass rods are well-suited for a range of industrial and decorative applications. They are commonly used in marine engineering, decorative hardware, and equipment subject to harsh conditions. Their versatility makes them a preferred material for both functional and aesthetic purposes.


Precision Manufacturing for Consistent Quality

Each rod is produced either by extrusion or drawing, ensuring consistent dimensions and mechanical properties. With a tolerance of 0.3 mm and available in various tempers from hard to annealed, these rods are tailored to meet diverse project requirements. Multiple shapes and sizes allow customization for specific engineering solutions.
