Our CuNi30 bar is a heavy-duty workhorse for chemical processing equipment, built to handle the nastiest environments without breaking a sweat. This copper-nickel alloy, with 30% nickel and a dose of manganese, is our top pick for applications where corrosion resistance and durability are critical.

Let’s dive into why CuNi30 bar rocks. Its standout feature is its ability to resist corrosion from harsh chemicals—acids, alkalis, you name it. Whether it’s piping, valves, or heat exchangers in a chemical plant, this bar keeps performing where other materials would corrode away. It’s a go-to for industries like petrochemicals, pharmaceuticals, and fertilizer production, where equipment needs to stay reliable under brutal conditions.

Beyond corrosion resistance, CuNi30 bar is tough and versatile. It’s stable up to 500°C, making it perfect for high-temperature heat exchangers and processing systems. Its electrical conductivity—around 10% IACS—is solid for applications like resistors or electrical components in chemical setups. Plus, its mechanical strength ensures it can handle the stresses of industrial environments without cracking.

This bar is super easy to work with. Its excellent formability lets you machine, weld, or shape it into whatever your project demands—bars, rods, or custom plates. Need a specific size for a unique valve or pipe? We can customize it to fit your specs, making fabrication a breeze and saving you time on the production line.

The industry’s trending toward materials that are durable, efficient, and sustainable, and CuNi30 bar checks all the boxes. It’s recyclable, which is awesome for eco-friendly projects, and its long lifespan means fewer replacements and less waste. With chemical processing plants pushing for greener operations and tougher equipment—think advanced reactors and carbon capture systems—CuNi30’s reliability is in high demand.

Compared to other materials, CuNi30 stands tall. Pure copper’s great for conductivity but falls apart in chemical environments. CuNi10 is more conductive but less resistant to corrosion and heat, making CuNi30 the better choice for chemical processing. Stainless steel’s strong but doesn’t always match CuNi30’s chemical resistance or formability in harsh settings. This bar hits the sweet spot for heavy-duty applications.

We craft our CuNi30 bar to meet strict standards like ISO 9001, so you’re getting quality you can trust every time. Whether you’re building chemical plant piping or heat exchangers, this bar’s ready to deliver. Got a custom need? Let us know, and we’ll make it happen.
