Based in the industrious city of Hamilton, Neesham Flanges has built a reputation for precision and reliability in the manufacturing sector. We specialize in producing high-performance flanges, with our Copper Nickel 7030 range standing as a testament to our commitment to quality. Understanding the demanding nature of marine and industrial applications, we supply components that are engineered to endure, ensuring your projects benefit from both local craftsmanship and materials designed for long-term resilience in the most challenging environments.
The exceptional durability of Copper Nickel 7030 Flanges comes from a specific blend of approximately 70% copper and 30% nickel, enhanced with small amounts of iron and manganese. This unique composition grants the material remarkable resistance to saltwater corrosion and biofouling, while also providing impressive strength across a wide range of temperatures. It’s a material that doesn’t just hold its shape under pressure; it actively fights back against the harsh elements that would quickly degrade lesser metals, making it a fundamentally robust choice.
