Bright Resistance Alloy Copper Nickel Cuni2 Rod Manufacturer

CuNi Series

DLX alloy offer CuNi2 Copper Alloys, and it consists of Copper (Bal) as primary components. Additionally, CuNi2 alloy may have Nickel (0.7% - 2.2%), Nickel (0.7% - 2.2%) in trace amounts.

CuNi2 (2.0802) is a copper-nickel alloy (CuNi alloy) with low resistivity for use at temperatures up to 300℃. CuNi2 is used for heating resistance alloy products Copper nickel alloy CuNi 1 have low resistance, and working temperature upto 200 degree. CuNi2 Copper nickel alloy also has good corrosion-resistant, It is easy to be processed and lead welded. CuNi2 is used to make the key components in the thermal overload relay, low resistance thermal circuit breaker, and the electrical appliances. It is also an important material for electrical heating cable.

We’re proud to be a leading manufacturer of CuNi2 rods, a copper-nickel alloy that’s got a solid rep in the industry. This stuff is a workhorse—low resistivity, great corrosion resistance, and super easy to work with. Let’s break it down and tell you why CuNi2 is a big deal for us and our customers.

CuNi2, with its 2% nickel content, is our go-to for low-temperature applications. Think heating cables in electric blankets, resistors in car seats, or even low-voltage circuit breakers. It’s got this sweet spot of electrical performance that makes it perfect for these kinds of jobs. Plus, it’s tough against corrosion, especially in salty, marine environments. That’s why you’ll find it in everything from ship components to offshore platforms. It’s like the alloy equivalent of a reliable pickup truck—affordable, durable, and gets the job done.

What makes CuNi2 stand out is its versatility. We produce it in rods, wires, and strips, with sizes ranging from super fine (0.02mm wires) to chunky (30mm rods). It’s bright, annealed, and soft, so it’s a breeze to shape or weld. And let’s talk cost—it’s one of the most budget-friendly copper-nickel alloys out there. Compared to something like CuNi44, which has way more nickel, CuNi2 gives you solid performance without breaking the bank. Our customers in automotive and electronics love it for that reason.

The industry’s moving fast, and we’re keeping up. Demand for CuNi2 is growing, especially with the push for electric vehicles and renewable energy. Think battery pack connectors or components in wind turbines—CuNi2’s corrosion resistance and conductivity make it a natural fit. We’re also seeing more automation in manufacturing, like resistance welding systems, where CuNi2 rods shine as electrodes. Sustainability’s a big deal too. Our production processes are dialed in to meet strict environmental regs like RoHS, and the alloy itself is fully recyclable, which keeps our eco-conscious clients happy.

We’re not just churning out rods; we’re innovating. Our team’s constantly tweaking alloy compositions to boost performance, like improving conductivity for next-gen electronics or refining surface finishes for precision applications. The market’s hot—reports say copper-nickel alloys are growing at a 5-6% CAGR, driven by marine, automotive, and energy sectors. We’re right in the thick of it, supplying to over 50 countries and working with industries that need reliable, high-quality materials.

Sure, CuNi2 isn’t perfect for every job. If you need something for super high temperatures or extreme strength, we’d point you to CuNi44 or even a nickel-chromium alloy. But for low-to-medium temp applications, CuNi2’s hard to beat. It’s non-magnetic, stable, and doesn’t flinch in harsh environments. We’ve got the production know-how to deliver it in whatever form you need, backed by ISO:9001 certification and a supply chain that’s as solid as our rods.

So, whether you’re building heating systems, automotive parts, or marine gear, our CuNi2 rods are ready to roll. It’s not just metal—it’s a solution that’s helping power the future, and we’re stoked to be part of it.
