Product Description
CuZn39Pb2Sn Naval Brass Rod
We fabricate a finest range of Naval Brass, which are renowned for their high strength, rust proof and durability features. Naval brass is a copper alloy containing 60% copper, 75% tin and around 39.25% zinc. These are made up of high-grade raw material and can be availed in the form of sheet, plate, rods and circle. Our range of naval brass is broadly used in marine and construction industry.

Marine-Grade DurabilityNaval Brass Rods (CuZn39Pb2Sn) are engineered to withstand the harshest saline and seawater environments. Their corrosion resistance makes them exceptionally suited for marine hardware, shipbuilding, and parts exposed to aggressive conditions, such as propeller shafts and condenser tubes.
Precision and FlexibilityOffered in standard and custom lengths (1 or 2 meters) and diameters (10100 mm), these rods provide versatility for diverse industrial and marine applications. Manufactured to strict tolerances and with various tempers, they ensure accuracy and reliability in critical installations.
Superior MachinabilityEnhanced by a lead content of 1.02.0%, these naval brass rods are designed for efficient machining and finishing processes. Their smooth, polished surface and excellent workability make them a preferred choice for manufacturers, suppliers, and service providers across India.
FAQs of CuZn39Pb2Sn Naval Brass Rod:
Q: How is CuZn39Pb2Sn Naval Brass Rod typically used in marine applications?
A: Naval Brass Rods made from CuZn39Pb2Sn are widely used for marine hardware, shipbuilding, shafting, propeller shafts, condenser tubes, and pump parts due to their high resistance to corrosion in seawater and robust mechanical strength.
Q: What benefits does the addition of lead and tin provide to this naval brass alloy?
A: Adding 1.02.0% lead improves the alloys machinability, enabling cleaner and more precise cuts during fabrication. The tin content (0.51.5%) enhances corrosion resistance, particularly in saline and seawater settings, making the brass suitable for long-term marine exposure.
Q: When should I choose this brass rod over other types of marine alloys?
A: Choose CuZn39Pb2Sn Naval Brass Rod when your project demands strong corrosion resistance, good machinability, and high mechanical properties in marine and saline environments. Its ideal for critical parts requiring durability and a polished finish, like shafting and condenser tubes.
Q: Where are these naval brass rods commonly supplied from in India?
A: These rods are distributed, exported, and supplied by manufacturers, traders, and service providers across India, catering to both domestic shipbuilding sectors and international marine hardware markets.
Q: What is the standard packaging process for CuZn39Pb2Sn Naval Brass Rods?
A: Naval brass rods are typically packaged in standard export packaging, designed to protect the rods polished finish and maintain their precision tolerances during domestic and international transport.
Q: How does the manufacturing process ensure product quality and consistency?
A: Manufacturers adhere to ASTM B21 and IS 2912 standards, using strict alloying processes, controlled tempering (usually Half Hard or Hard), and precision finishing to achieve consistent quality, mechanical properties, and dimensional accuracy for each batch of rods.
