Cold Drawing Treatment Copper Bar And Copper Alloys with Ni-Cr Conductor Material

Our cold drawn copper bar and NiCr alloy conductor material are a dynamic duo for manufacturers who need top-tier conductivity and heat-resistant performance. Whether you’re building electrical systems or high-temperature heating components, these materials deliver the reliability and versatility to elevate your OEM projects.

Let’s start with the cold drawn copper bar. The cold drawing process works magic, boosting tensile strength to 300-400 MPa while keeping copper’s stellar electrical conductivity (~0.017 µΩ·m, one of the best out there). This makes it perfect for busbars, electrical connectors, and wiring where efficiency is key. The process also delivers a smooth, bright surface finish and precise dimensions, which saves time in manufacturing and ensures a polished look for high-end applications. While copper isn’t great in corrosive environments like seawater, its ductility and machinability make it a breeze to shape into custom components.

On the other hand, our NiCr alloy conductor material—typically 60-80% nickel and 15-20% chromium—is built for heat and durability. With a high resistivity of 1.0-1.5 µΩ·m and a low temperature coefficient of resistance (~100 ppm/°C), it’s a go-to for precision resistors and heating elements in toasters, ovens, and industrial furnaces. It thrives at temperatures up to 1200°C, forming a protective chromium oxide layer that fights off oxidation and corrosion in harsh, oxidizing environments (just avoid sulfur-heavy settings). Its tensile strength (600-800 MPa) and hardness (180-220 HV) ensure it holds up under stress, while its ductility allows for forming into wires, strips, or custom shapes.

The market for these materials is hot, with a growth rate of about 5-6% annually, driven by demand in electrical, aerospace, and industrial sectors. Cold drawn copper bars are essential for energy-efficient electrical systems, while NiCr alloys dominate in heating and aerospace applications like turbine components. Compared to CuNi44, copper offers unmatched conductivity for low-resistance needs, while NiCr excels in high-temperature stability.

We produce these materials with strict quality controls to ensure consistent performance—whether it’s the conductivity of our copper bars or the resistivity and heat resistance of our NiCr alloys. We’re also exploring sustainable practices, like recycling, to keep our process eco-friendly. While raw material prices can fluctuate, the durability and efficiency of these materials make them a cost-effective choice for long-term performance.

In short, our cold drawn copper bar and NiCr alloy conductor material are your ticket to high-performance manufacturing. From electrical systems to high-temperature heating, they deliver the conductivity, strength, and reliability you need to get the job done. Ready to power up your next project?
