Naval Brass Rods
Kanak Pipe Industries, situated in Mumbai, India, stands as a prominent manufacturer specializing in Naval Brass Rods. The lead-free naval brass they produce is crafted from a composition of 60% copper, 39.2% zinc, and 0.8% tin. The incorporation of tin, alongside zinc, enhances the alloy’s corrosion resistance in seawater. Consequently, this alloy exhibits remarkable resistance to dezincification, preventing the adverse effects of seawater impingement at elevated temperatures. Moreover, the alloy is lauded for its durability, resilience against wear, fatigue, galling, and resistance to stress corrosion cracking.
Key aspects and properties of Naval Brass Rods :
- Composition: The rods are made from a lead-free naval brass composition consisting of 60% copper, 39.2% zinc, and 0.8% tin.
- Corrosion Resistance: The addition of tin enhances corrosion resistance, especially in seawater. This makes the alloy resistant to dezincification even at higher temperatures.
- Seawater Performance: The alloy is specifically designed to resist impingement by seawater, making it suitable for marine applications.
- Durability: Naval Brass rods are known for their durability, exhibiting resistance to wear, fatigue, galling, and stress corrosion cracking.
- Manufacturer: Kanak Pipe Industries, based in Mumbai, India, is a leading manufacturer of these Naval Brass rods.
