For manufacturers and engineers in Manila and beyond who demand resilience against the sea, Corazon Pipes and Tubes stands as a trusted partner. Based right here in the Philippines, we specialize in supplying robust materials built for challenging environments, with our Copper Nickel 7030 tubing being a prime example. This particular alloy is engineered to offer superior performance where it matters most, providing a reliable solution for projects that cannot afford compromise, especially in our coastal setting. We take pride in delivering quality that withstands the test of time and the elements.
The strength of Copper Nickel 7030, or CuNi 70/30, lies in its thoughtful composition, primarily a blend of 70% copper and 30% nickel. This combination is enhanced with small but crucial additions of iron and manganese, which work together to significantly boost its resistance to corrosion and erosion. The result is a tubing material that is not only exceptionally durable but also maintains excellent mechanical properties, including high tensile strength and good ductility, allowing it to perform reliably under pressure and in demanding service conditions.
