We’re stoked about our copper-nickel alloy rods, tailor-made for heating cables and thermal overload relays. These rods, ranging from CuNi2 to CuNi44, are high-performance champs that deliver reliability and efficiency for all kinds of industrial needs. Let’s dive into why they’re a top pick for our customers.

Our CuNi rods are perfect for applications where consistent heating and durability are key. CuNi2, with its low nickel content, is a budget-friendly star for heating cables in things like electric blankets or car seat warmers. CuNi10 steps it up for more demanding setups, like underfloor heating or marine-grade relays, thanks to its solid corrosion resistance. And CuNi44? It’s the heavy hitter for high-precision, high-temp jobs, like thermal relays in industrial systems, handling up to 600°C. All our rods are super ductile, easy to weld, and non-magnetic, making them a breeze to work with.

The industry’s humming, and we’re right in the thick of it. Copper-nickel alloys are seeing 5-7% growth yearly, fueled by demand in automotive, electronics, and HVAC sectors. Our rods are popping up in everything from EV thermal management systems to marine relays that shrug off salty corrosion. We’re shipping to over 50 countries, with ISO:9001 certification ensuring every rod’s top-notch. Plus, they’re 100% recyclable, meeting RoHS standards, which our eco-conscious clients totally dig.

What makes our rods shine is how we customize them for you. From 0.1mm wires to 50mm bars, we can tweak sizes or forms to fit your heating cables or relays perfectly. The bright, annealed finish means easy machining, and our R&D team’s always tinkering to boost performance for next-gen applications, like smart HVAC systems or advanced automotive electronics.

Each alloy’s got its niche. CuNi2 keeps costs low but isn’t built for extreme heat. CuNi10’s a great all-rounder for strength and affordability. CuNi44’s your go-to for high-temp precision but comes with a bigger price tag. Whatever your project, we’ve got the expertise to deliver the right rod for the job.

Our copper-nickel alloy rods aren’t just materials—they’re the backbone of efficient heating cables and reliable thermal overload relays. We’re pumped to craft these versatile solutions and help our clients keep their systems running smoothly, from cozy homes to high-tech factories.
