Bosega Pipes and Tubes, based in Cape Town, South Africa, specializes in providing top-notch **Copper Nickel Tubing**, celebrated for its remarkable resistance to corrosion, particularly in marine and saltwater settings. Crafted from copper-nickel alloys like 90/10 (C70600) and 70/30 (C71500), this tubing is designed for applications that demand both strength and protection against biofouling, erosion, and stress corrosion cracking. Bosega guarantees that each tube is produced with meticulous precision and adheres to international standards such as ASTM B466 and B111.
Copper nickel tubing boasts a distinctive blend of strength, flexibility, and resistance to seawater corrosion, making it an excellent choice for heat exchanger tubes, condensers, offshore platforms, and shipbuilding systems. The 90/10 alloy is known for its great weldability and moderate strength, while the 70/30 alloy offers enhanced strength and superior resistance in more challenging conditions. These tubes also retain their mechanical properties across a broad temperature range, making them suitable for transporting both cold and hot fluids.

Copper Nickel Tubing, typically composed of 90% copper and 10% nickel, is widely used in marine, chemical, and industrial applications due to its excellent corrosion resistance, especially in seawater and brackish environments. Its biofouling, pitting, and crevice corrosion resistance makes it ideal for heat exchangers, desalination plants, shipbuilding, and offshore oil platforms. Additionally, copper-nickel tubing is valued for its good thermal conductivity, strength, and durability in high-pressure applications, which makes it suitable for applications where both corrosion resistance and mechanical performance are critical.
