Our CuNi30 bar is a tough, reliable choice for industrial heating systems that need to go the distance. This copper-nickel alloy, with 30% nickel and a bit of manganese, is built to handle high heat and harsh conditions while keeping your systems running smoothly.

What makes CuNi30 bar stand out is its durability in demanding environments. It’s got excellent corrosion resistance, thanks to the nickel and manganese, so it holds up in chemical plants, industrial furnaces, and even humid settings where other materials would rust out. This makes it a top pick for heating elements, resistors, and thermocouples in industries like energy, manufacturing, and petrochemicals.

When it comes to heating, CuNi30 is a beast. It’s stable up to 500°C, delivering consistent performance for industrial furnaces, HVAC systems, and heating cables. Its electrical conductivity—around 10% IACS—is solid for applications needing stable resistivity, like precision resistors or thermocouple components. You get reliable heat transfer and accurate temperature control without worrying about breakdowns.

This bar is a dream to work with. Its high formability means you can machine, weld, or shape it into whatever your project needs—bars, rods, or custom profiles. Need something specific for your heating system? We can customize the dimensions or alloy specs to fit your setup, making manufacturing a breeze.

The industry’s pushing for materials that are durable, efficient, and sustainable, and CuNi30 bar checks all those boxes. It’s recyclable, which is great for eco-conscious projects, and its long lifespan means fewer replacements and less waste. With industrial heating systems getting smarter and more energy-efficient—think automated furnaces and renewable energy setups—CuNi30’s reliability and performance are in high demand.

Compared to other materials, CuNi30 holds its own. Pure copper’s a conductivity champ but can’t handle corrosion or high heat. CuNi44 has a slight edge in corrosion resistance but lower conductivity and higher cost, making CuNi30 a great middle ground. Nichrome’s awesome for extreme heat but lacks CuNi30’s corrosion resistance and versatility for electrical applications. This bar strikes the perfect balance for industrial needs.
