Choosing Copper Nickel 70/30 Pipes from Wissa Pipes and Tubes ensures outstanding corrosion resistance, high strength, and durability. Our Pipe is designed for diverse industrial applications, delivering reliability and performance in challenging environments while maintaining competitive pricing.
The strength of these pipes comes from a specific blend of approximately 70% copper and 30% nickel, often with small additions of iron and manganese. This precise composition grants them remarkable mechanical properties, including excellent tensile strength and a natural resistance to corrosion and erosion. They are particularly known for their ability to maintain integrity under stress, offering superb performance in both high-pressure systems and situations involving fast-moving fluids, making them a robust choice for challenging applications.
